DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Helene was
located near latitude 19.5 North, longitude 84.3 West. Helene is
moving toward the northwest near 12 mph (19 km/h), and this
general motion is expected to continue through early Wednesday. A
northward to north-northeastward motion at a faster forward speed
is expected on Wednesday and Thursday. On the forecast track, the
center of Helene will move across the far northwestern Caribbean
Sea through tonight, and then move across the eastern Gulf of
Mexico Wednesday and Thursday, potentially reaching the Gulf coast
of Florida late Thursday.

Data from an Air Force Reserve Hurricane Hunter aircraft indicate
that the system has acquired a well-defined center of circulation,
and maximum sustained winds have increased to near 45 mph (75 km/h)
with higher gusts. Additional strengthening is forecast, and
Helene is expected to become a hurricane on Wednesday. Continued
strengthening is anticipated after that time, and Helene could
become a major hurricane on Thursday.

Tropical-storm-force winds extend outward up to 140 miles (220 km)
to the east of the center.

Data from the Hurricane Hunter aircraft indicate that the minimum
central pressure is 1000 mb (29.53 inches).


HAZARDS AFFECTING LAND
----------------------
Key Messages for Helene can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC
and on the web at hurricanes.gov/text/MIATCDAT4.shtml

RAINFALL: Helene is expected to produce total rain accumulations of
4 to 8 inches over western Cuba and the Cayman Islands with isolated
totals around 12 inches. Over the eastern Yucatan Peninsula, 4 to 6
inches of rain are expected with isolated totals over 8 inches. This
rainfall brings a risk of considerable flooding.

Over the Southeastern U.S., Helene is expected to produce total rain
accumulations of 4 to 8 inches with isolated totals around 12
inches. This rainfall will likely result in areas of considerable
flash and urban flooding, with minor to moderate river flooding
likely, and isolated major river flooding possible.

For a complete depiction of forecast rainfall associated with
Helene, please see the National Weather Service Storm Total Rainfall
Graphic, available at hurricanes.gov/graphics_at4.shtml?rainqpf and
the Flash Flood Risk graphic at
hurricanes.gov/graphics_at4.shtml?ero.

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Ochlockonee River, FL to Chassahowitzka, FL...10-15 ft
Chassahowitzka, FL to Anclote River, FL...6-10 ft
Indian Pass, FL to Ochlockonee River, FL...5-10 ft
Anclote River, FL to Middle of Longboat Key, FL...5-8 ft
Tampa Bay...5-8 ft
Middle of Longboat Key, FL to Englewood, FL...4-7 ft
Englewood, FL to Bonita Beach, FL...3-5 ft
Charlotte Harbor...3-5 ft

For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_at4.shtml?peakSurge.

Storm surge could raise water levels by as much as 2 to 4 feet above
normal tide levels in areas of onshore winds along the southern
coast of Pinar del Rio, Cuba, including the Isle of Youth.

Storm surge could raise water levels by as much as 2 to 4 feet above
ground level in areas of onshore winds within the warning area along
the east coast of the Yucatan Peninsula.

WIND: Hurricane conditions are possible within the watch areas in
Cuba and Mexico by early Wednesday. Hurricane conditions are
possible within the U.S. watch areas Wednesday night and early
Thursday. Tropical storm conditions are expected in the warning
areas in the Cayman Islands, Cuba, and Mexico today. Tropical
storm conditions are expected in the warning area in the Lower
Florida Keys beginning on Wednesday, and are possible in the watch
area in the Middle Florida Keys beginning late Wednesday.

SURF: Swells generated by Helene will affect the southern coast
of Cuba and the Yucatan Peninsula of Mexico during the next couple
of days. Swells will spread northward toward the west coast of
Florida and the northeastern Gulf Coast on Wednesday and Thursday.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

Tropical Storm Helene, now formed, is projected to intensify.

As always, Florida will prepare for the worst and hope for the best. We already have nearly 18,000 linemen staged (and more en route), and are ready with search and rescue and roadway clearing crews.

Stay tuned to local and state emergency recommendations and alerts. Get preparations in place now for the storm and heed evacuation directives, if issued, from local officials.

These points from the @NWSNHC discussion on #Helene can't be emphasized enough. This is destined to be a BIG hurricane. Don't be fooled by recent storms. The forecast extent of tropical storm winds is nearly twice the size of Debby and Idalia, with possibly a stronger core.​

Helene's explosive forecast one of the 'most aggressive' in hurricane history

Dinah Voyles Pulver
USA TODAY
PublIshed 4:55 p.m. ET Sept. 24, 2024

The forecast for Helene to transition from a potential tropical cyclone to a Category 3 hurricane appears to be the fastest progression ever predicted for a depression by the National Hurricane Center.

“They had never forecast a major hurricane within 60 hours for a disturbance below tropical storm level,” said Sam Lillo, a meteorologist and software engineer for DTN Weather, based on a computer analysis of the center’s historical forecast data. "The entire forecast is also basically faster than has ever been seen for 36 hours and 48 hours from a tropical depression.”

The National Hurricane Center didn't have that stat at the ready Tuesday as they were focused on operational forecasting for Helene, now a tropical storm, but "it's either the highest or one of the highest," said John Cangialosi, one of the center's senior hurricane specialists.

The forecast for a "70-knot increase in 72 hours on Monday was among the most aggressive forecasts" for a potential tropical cyclone, Cangialosi said.

"It's an aggressive forecast for good reason," he said. "We're trying to get ahead of the possible rapid intensification before it gets to Florida."

Tropical Storm Helene Discussion Number 8...Corrected
NWS National Hurricane Center Miami FL AL092024
400 AM CDT Wed Sep 25 2024

Corrected Helen to Helene

Helene has strengthened some since the last advisory. Reports from
an Air Force Reserve Hurricane Hunter aircraft indicate that
the central pressure has fallen to 985 mb, and that the maximum
850 mb flight-level were 58 kt in the northeastern quadrant. A
dropsonde in the northwest quadrant reported a splash wind of 59
kt, but the boundary-layer average suggested sustained winds closer
to 45 kt. Based on these data and increasing satellite intensity
estimates, the initial intensity is increased to 55 kt. Despite
the increased intensity, the aircraft data, along with radar data
from Mexico and Cuba, show that Helene has not yet formed a
well-defined inner core.

The initial motion is 325/8 kt. Helene should turn northward
during the next 12 h or so on the western side of a mid-level
ridge, and then it should accelerate northward to
north-northeastward as it become embedded in the deep-layer flow
between the ridge and a mid-latitude trough/developing cut-off low
over the Mississippi valley. This motion should bring the center
near the northeastern coast of the Yucatan Peninsula this morning,
then across the eastern Gulf of Mexico tonight and Thursday to a
landfall along the northeast coast of the Gulf of Mexico late
Thursday or Thursday night. After landfall, Helene should curve
cyclonically around the cut-off low until it dissipates. The new
forecast track is little changed from the previous track.

Over the next couple of days, Helene will be moving through an
environment of low vertical wind shear, ample environmental
moisture, and over waters of high oceanic heat content. All
guidance forecasts steady to rapid intensification, including the
RI indices associated with the SHIPS model. The latest forecast
calls for a 105 kt intensity by 36 h, and this could be
conservative as some of the guidance is stronger. After landfall,
Helene is forecast to weaken and become post-tropical as it gets
tangled up in the baroclinic system over the southeastern United
States.

Helene's wind field is predicted to grow to a very large size in the
NHC forecast. Therefore storm surge, wind, and rainfall impacts
will likely extend well away from the center and outside the
forecast cone, particularly on the east side. In addition, the fast
forward speed while Helene crosses the coast will likely result in
farther inland penetration of strong winds over parts of the
southeastern United States after landfall.


KEY MESSAGES:

1. Helene is forecast to intensify and be near hurricane strength
when it passes near the northeastern coast of the Yucatan
Peninsula during the next several hours, where a Hurricane Warning
is in effect.

2. Helene is expected to rapidly intensify and grow in size over the
eastern Gulf of Mexico. There is a danger of life-threatening storm
surge along the entire west coast of the Florida Peninsula and
Florida Big Bend. The highest inundation levels are expected along
the coast of the Florida Big Bend. Residents in those areas should
follow advice given by local officials and evacuate if told to do
so.

3. Damaging hurricane-force winds are expected along portions of
coast of the Florida Big Bend, where a Hurricane Warning is now in
effect. Preparations to protect life and property should be
completed by early Thursday since tropical storm conditions are
expected to begin within this area on Thursday.

4. Tropical Storm Helene will bring heavy rain to portions of the
western Caribbean with potentially significant flooding across
western Cuba and the northeastern Yucatan Peninsula. Considerable
and potentially life-threatening flash and urban flooding is
expected across portions of Florida, the Southeast, the Southern
Appalachians, and the Tennessee Valley beginning today through
Friday. This includes the risk of landslides across the southern
Appalachians. Widespread minor to moderate river flooding is likely,
and isolated major river flooding is possible.

Know Your Zone, Know Your Home


Every year it's important for residents to know if they live an evacuation zone, a low-lying, flood prone area, a mobile home or an unsafe structure during hurricane season. These areas and buildings are most likely to be evacuated and knowing these zones helps Floridians prepare to evacuate and better understand orders from local officials.

This year, it is also very important for residents to know their home. If an evacuation order is not issued for your area and your house is not in an evacuation zone, you may consider sheltering in place. If you shelter in place, it’s important to know your home and its ability to withstand strong winds and heavy rain.

Instructions to Know Your Zone, Know Your Home

• Click Know Your Zone Map (Please note, the Division is continuously updating and making improvements to this website. If you are prompted to log in or are unable to access the map, please try again at a later time.)
• Type in your address
• Know Your Zone - Find if your address is in one of the colored evacuation zones (these are flood zones)
• If you are in an evacuation zone, listen to evacuation orders from local officials (Typically Zone A is the most vulnerable and the most likely to evacuate first. Zone E is most likely to evacuate last)
• If an evacuation order is not issued for your area, you may consider sheltering in place. Not all evacuations zones are always ordered.
• If you shelter in place, it’s important to Know Your Home and its ability to withstand strong winds and heavy rain

Hurricane Helene Discussion Number 9
NWS National Hurricane Center Miami FL AL092024
1000 AM CDT Wed Sep 25 2024

Air Force Reserve and NOAA Hurricane Hunter aircraft have been
investigating Helene, with each plane recently measuring peak
flight-level winds of 81 kt and 78 kt, respectively. Helene has
therefore become a hurricane with an estimated intensity of 70 kt.
Dropsonde data also indicate that the pressure has fallen to about
979 mb. Radar data from Mexico and Cuba, as well as reconnaissance
reports, indicate that Helene has formed a partial, elliptical
eyewall that is open on the east side.

Helene has turned north-northwestward (330/9 kt) and is expected to
turn northward and north-northeastward later today and tonight,
bringing the center to the coast of the Florida Big Bend Thursday
evening. After landfall, Helene is expected to interact with a
deep-layer trough over the Lower Mississippi Valley and swing back
to the northwest and stall near the Tennessee Valley late Friday
into the weekend. The track guidance remains tightly clustered,
and the NHC forecast is generally just an update of the previous
prediction. It is still too soon at this point to be overly focused
on an exact landfall location and time, since NHC track forecasts
can be off by an average of 60 nm at the 36-hour forecast time.

Helene is expected to move through/over an environment of
relatively low shear, strong upper-level divergence, and sea
surface temperatures of 29-31 degrees Celsius, all of which should
foster additional strengthening. Rapid Intensification (RI)
indices indicate a high chance of RI during the next 24 hours, and
as a result the NHC intensity forecast shows Helene becoming a
major hurricane by Thursday morning. There is still some
uncertainty on exactly how strong Helene will get, and upward
adjustments to the forecast intensity could be required in
subsequent advisories if Helene rapidly intensifies more than
forecast. Regardless, Helene is forecast to be a large major
hurricane when it reaches the Big Bend coast of Florida. As a
result, storm surge, wind, and rainfall impacts will likely extend
well away from the center and outside the forecast cone,
particularly on the east side. In addition, the fast forward speed
while Helene crosses the coast will likely result in farther inland
penetration of strong winds over parts of the southeastern United
States after landfall, including strong gusts over higher terrain
of the southern Appalachians.


KEY MESSAGES:

1. Hurricane and tropical storm conditions are expected over
northeastern portions of the Yucatan Peninsula of Mexico today where
Tropical Storm and Hurricane Warnings are in effect. Tropical storm
conditions are occurring over portions of western Cuba within the
Tropical Storm Warning area, and hurricane conditions are possible
today within the Hurricane Watch area.

2. Due to the large size of Helene, there is a danger of
life-threatening storm surge along the entire west coast of the
Florida Peninsula and Florida Big Bend. The highest inundation of
greater than 10 ft is expected along the Florida Big Bend coast.
Residents in those areas should follow advice given by local
officials and evacuate if told to do so.

3. Devastating hurricane-force winds are expected across portions
of northern Florida and southern Georgia where the core of Helene
moves inland. Preparations to protect life and property should be
completed by early Thursday since tropical storm conditions are
expected to begin within these areas on Thursday. Because of
Helene’s expected fast forward speed, damaging and life-threatening
wind gusts, are expected to penetrate well inland over portions of
the southeastern United States, including in the higher terrain of
the southern Appalachians.

4. Helene will bring heavy rain to portions of the western
Caribbean with potentially significant flooding across western Cuba
and the northeastern Yucatan Peninsula into early Thursday.
Considerable and potentially life-threatening flash and urban
flooding is expected across portions of northwestern and northern
Florida, the Southeast, southern Appalachians, and the Upper
Tennessee Valley Wednesday through Friday. This includes the risk of
landslides across the southern Appalachians. Widespread minor to
moderate river flooding is likely, and isolated major river flooding
is possible.

Governor Ron DeSantis Issues Updates on State Preparedness Efforts Ahead of Hurricane Helene

On September 25, 2024, in News Releases, by Staff


TALLAHASSEE, Fla.—Today, Governor Ron DeSantis was joined by Florida Division of Emergency Management (FDEM) Executive Director Kevin Guthrie in Tampa to meet with power and utility linemen staged and ready to respond to power outages caused by Hurricane Helene, and to provide updates on state preparedness efforts before the storm’s landfall.

Following Governor DeSantis’ request, FEMA approved the state’s pre-landfall disaster declaration request. This will provide important resources and assistance from the federal government, including personnel, equipment and supplies, as well as making available funding sources for emergency protective measures. The pre-landfall declaration request is for the 41 Florida counties included in Executive Order 24-208.

Governor DeSantis issued Executive Order 24-209 on September 24, updating EO 24-208 and declaring a state of emergency for 61 counties, which allows for state officials to make critical resources available to communities ahead of any potential storm impacts.

Voluntary and mandatory evacuation orders are in effect in multiple counties statewide. Residents need to evacuate as soon as possible if they are under a mandatory evacuation order. Counties under evacuation orders can be found at FloridaDisaster.org/EvacuationOrders.

Residents in need of assistance finding or going to a shelter in the Big Bend region for Hurricane Helene can call (800) 729-3413. FDEM team members will be conducting callbacks from messages received last night, as well as accepting new calls today, to facilitate shelter coordination. For additional resources and assistance, residents can call the State Assistance Information Line (SAIL) at (800) 342-3557. Assistance is available in English, Spanish and Haitian-Creole.

As of 11AM ET, the storm has strengthened into Hurricane Helene, with maximum sustained winds of 80 mph. Helene is expected to move across the eastern Gulf of Mexico and to the Florida Big Bend coast by Thursday evening. Additional strengthening is forecast, and Helene is expected to be a major hurricane when it reaches landfall.

Watches and warnings in effect include

Hurricane Warning: western Alachua, coastal Citrus, Columbia, Dixie, Franklin, Gadsden, Gilchrist, Gulf, Hamilton, coastal Hernando, Jefferson, Lafayette, Leon, Levy, Liberty, Madison, western Marion, coastal Pasco, Suwannee, Taylor and Wakulla counties

‘Nightmare scenario’: Hurricane Helene will make catastrophic Florida landfall; Tallahassee in direct path

By DAVID SCHUTZ | dschutz@sunsentinel.com | South Florida Sun Sentinel, ROBIN WEBB | rwebb@sunsentinel.com | South Florida Sun Sentinel, BILL KEARNEY | South Florida Sun Sentinel and ANGIE DIMICHELE | adimichele@sunsentinel.com | South Florida Sun Sentinel

UPDATED: September 26, 2024 at 8:13 a.m.
...
The state’s capital, Tallahassee, is directly in Helene’s path. The hurricane’s center is forecast to make landfall late Thursday or early Friday morning.

Helene will have one of the largest wind fields of any storm to hit the southeast U.S. in years, according to Colorado State University hurricane researcher Phil Klotzbach, who said that since 1988, only three Gulf hurricanes were bigger than Helene’s predicted size: 2017’s Irma, 2005’s Wilma and 1995’s Opal.

Forecasters said Helene will intensify further than previously forecast, forecasting 130 mph winds Thursday before landfall.

“This forecast, if realized, is a nightmare surge scenario for Apalachee Bay,” the National Weather Service office said. “Please, please, please take any evacuation orders seriously!”

DISCUSSION AND OUTLOOK
----------------------
At 700 AM CDT (1200 UTC), the center of Hurricane Helene was located
near latitude 24.5 North, longitude 85.9 West. Helene is moving
toward the north-northeast near 12 mph (19 km/h). This general
motion is expected to continued with a significant increase in
forward speed during the next 24 hours. On the forecast track,
Helene will move across the eastern Gulf of Mexico today and cross
the Florida Big Bend coast this evening or early Friday morning.
After landfall, Helene is expected to turn northwestward and slow
down over the Tennessee Valley on Friday and Saturday.

Maximum sustained winds have increased to near 100 mph (155 km/h)
with higher gusts. Additional strengthening is forecast, and Helene
is expected to be a major hurricane when it reaches the Florida Big
Bend coast this evening. Weakening is expected after landfall, but
Helene's fast forward speed will allow strong, damaging winds,
especially in gusts, to penetrate well inland across the
southeastern United States, including over the higher terrain of the
southern Appalachians.

Hurricane-force winds extend outward up to 60 miles (95 km) from
the center and tropical-storm-force winds extend outward up to 345
miles (555 km). The Key West Naval Air Station recently reported
sustained winds of 41 mph (66 km/h) and a wind gust of 55 mph (89
km/h). An observation in Sand Key recently reported sustained
winds of 45 mph (72 km/h) and a gust to 58 mph (93 km/h).

The estimated minimum central pressure based on data from the
NOAA and Air Force Reserve Hurricane Hunter aircraft is 960 mb
(28.35 inches).


HAZARDS AFFECTING LAND
----------------------
Key Messages for Helene can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC
and on the web at hurricanes.gov/text/MIATCDAT4.shtml

STORM SURGE: The combination of a life-threatening storm surge and
the tide will cause normally dry areas near the coast to be flooded
by rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Carrabelle, FL to Suwannee River, FL...15-20 ft
Apalachicola, FL to Carrabelle, FL...10-15 ft
Suwannee River, FL to Chassahowitzka, FL...10-15 ft
Chassahowitzka, FL to Anclote River, FL...8-12 ft
Indian Pass, FL to Apalachicola, FL...6-10 ft
Anclote River, FL to Middle of Longboat Key, FL...5-8 ft
Tampa Bay...5-8 ft
Middle of Longboat Key, FL to Englewood, FL...4-7 ft
East of Mexico Beach, FL to Indian Pass, FL...3-5 ft
Englewood, FL to Flamingo, FL...3-5 ft
Charlotte Harbor...3-5 ft

For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_at4.shtml?peakSurge.

Storm surge could raise water levels by as much as 2 to 4 feet above
normal tide levels in areas of onshore winds along the southern
coast of Pinar del Rio, Cuba, including the Isle of Youth.

WIND: Hurricane conditions are expected within the U.S. hurricane
warning area late today. Tropical storm conditions have
already begun in the Florida Keys and portions of south
Florida, and these conditions are expected to spread northward
across the state and into Georgia and South Carolina through
tonight.

Tropical storm conditions are expected over portions of the warning
area in western Cuba during the next few hours.

RAINFALL: Hurricane Helene is expected to produce total rain
accumulations of 4 to 8 inches over western Cuba, the Cayman Islands
and the northeast Yucatan Peninsula, with isolated totals around 12
inches. This rainfall brings a risk of considerable flooding.

Over portions of the Southeastern U.S. into the Southern
Appalachians, Helene is expected to produce total rain accumulations
of 6 to 12 inches with isolated totals around 18 inches. This
rainfall will likely result in catastrophic and potentially
life-threatening flash and urban flooding, along with significant
river flooding. Numerous landslides are expected in steep terrain
across the southern Appalachians.

For a complete depiction of forecast rainfall associated with
Hurricane Helene, please see the National Weather Service Storm
Total Rainfall Graphic, available at
hurricanes.gov/graphics_at4.shtml?rainqpf and the Flash Flood Risk
graphic at hurricanes.gov/graphics_at4.shtml?ero.

TORNADOES: The risk for several tornadoes will gradually increase
today through tonight. The greatest threat is expected from parts of
northern Florida into southeast Georgia, the Midlands and Low
Country of South Carolina, and southern North Carolina.

SURF: Swells generated by Helene will affect much of Florida and
the coasts of Georgia and the Carolinas during the next couple of
days. Swells will also continue across portions of Cuba and the
Yucatan Peninsula through tonight. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.

Hurricane Helene Discussion Number 13
NWS National Hurricane Center Miami FL AL092024
1000 AM CDT Thu Sep 26 2024

Helene is gaining strength as it approaches the Florida Big Bend. A
large eye has become apparent in satellite images, and that feature
has been gradually clearing out over the past few hours. Convective
banding is wrapping around the eye, and recent microwave images and
reports from the NOAA and Air Force Hurricane Hunter aircraft
indicate than an eyewall is almost completely closed. The minimum
pressure has been dropping steadily to near 960 mb, and based on the
aircraft flight-level wind data, the initial intensity is estimated
to have increased to 90 kt. There have been several reports of
tropical-storm-force winds occurring in portions of South Florida
and the Florida Keys during the past few hours.

The large hurricane is picking up speed and has turned slightly to
the north-northeast. The latest initial motion is 025/12 kt. A
notably faster north-northeastward motion is expected through
landfall, which is expected to occur in the Florida Big Bend region
this evening. After Helene moves inland, it is forecast to track
over Georgia and then slow down or stall over the Tennessee Valley
when it merges with a mid- to upper-level low pressure system. Only
minor changes were made to the previous NHC track forecast.

Significant intensification is expected until Helene reaches the
coast since the overall atmospheric and oceanic conditions will
remain conducive. The amount of strengthening will likely depend on
how much the inner core can contract and consolidate. The HWRF and
HMON models show significant strengthening to category 4 status,
while most of the other models are a little lower. The main message
is that Helene will likely make landfall as a large major hurricane
in the Florida Big Bend this evening, and all preparations in the
hurricane warning area should be rushed to completion.

It should also be re-emphasized that Helene is a very large
hurricane. In fact, comparing the system with previous hurricanes
in the Gulf of Mexico over the past couple of decades, Helene is at
the upper bound in terms of size. As a result, storm surge, wind,
and rainfall impacts will extend far away from the center and well
outside the forecast cone, particularly on the east side. In
addition, the fast forward speed when Helene moves inland will
result in a far inland penetration of strong winds over parts of the
southeastern United States, including strong gusts over higher
terrain of the southern Appalachians. Accordingly, a
higher-than-normal gust factor is indicated in the official forecast
while Helene is inland.


KEY MESSAGES:

1. A catastrophic and deadly storm surge is likely along portions
of the Florida Big Bend coast, where inundation could reach as high
as 20 feet above ground level, along with destructive waves. There
is also a danger of life-threatening storm surge along the remainder
of the west coast of the Florida Peninsula. Residents in those
areas should follow advice given by local officials and evacuate if
told to do so.

2. Potentially catastrophic hurricane-force winds are expected
within the eyewall of Helene when it makes landfall in the Florida
Big Bend region this evening. Preparations to protect life and
property should be rushed to completion. Damaging and
life-threatening hurricane-force winds, especially in gusts, will
penetrate well inland over portions of northern Florida and southern
Georgia later today and tonight where Hurricane Warnings are in
effect. Strong wind gusts are also likely farther north across
portions of northern Georgia and the Carolinas, particularly over
the higher terrain of the southern Appalachians.

3. Catastrophic and life-threatening flash and urban flooding,
including numerous significant landslides, is expected across
portions of the southern Appalachians through Friday. Considerable
to locally catastrophic flash and urban flooding is likely for
northwestern and northern Florida and the Southeast through Friday.
Widespread significant river flooding and isolated major river
flooding are likely.

DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the eye of Hurricane Helene was located
near latitude 27.9 North, longitude 84.6 West. Helene is moving
toward the north-northeast near 23 mph (37 km/h). A continued fast
motion to the north-northeast is expected through landfall in the
Florida Big Bend this evening. After landfall, Helene is expected to
turn northwestward and slow down over the Tennessee Valley on
Friday and Saturday.

Maximum sustained winds have increased to near 125 mph (205 km/h)
with higher gusts. Helene is a category 3 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Additional strengthening is
expected, and Helene will likely be an extremely dangerous category
4 hurricane at landfall. Weakening is expected after Helene moves
inland, but the fast forward speed will allow strong, damaging
winds, especially in gusts, to penetrate well inland across the
southeastern United States, including over the higher terrain of the
southern Appalachians.

Hurricane-force winds extend outward up to 60 miles (95 km) from the
center and tropical-storm-force winds extend outward up to 310 miles
(500 km). A weather station at Venice Municipal Airport recently
reported a sustained wind of 46 mph (74 km/h) with a gust of 69 mph
(111 km/h). Another observation near Venice Beach reported a
sustained wind of 51 mph (82 km/h) with a gust to 66 mph (106
km/h).

The estimated minimum central pressure based on data from the Air
Force Hurricane Hunters is 951 mb (28.09 inches).


HAZARDS AFFECTING LAND
----------------------
Key Messages for Helene can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC
and on the web at hurricanes.gov/text/MIATCDAT4.shtml

STORM SURGE: The combination of a life-threatening storm surge and
the tide will cause normally dry areas near the coast to be flooded
by rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Carrabelle, FL to Suwannee River, FL...15-20 ft
Apalachicola, FL to Carrabelle, FL...10-15 ft
Suwannee River, FL to Chassahowitzka, FL...10-15 ft
Chassahowitzka, FL to Anclote River, FL...8-12 ft
Indian Pass, FL to Apalachicola, FL...6-10 ft
Anclote River, FL to Middle of Longboat Key, FL...5-8 ft
Tampa Bay...5-8 ft
Middle of Longboat Key, FL to Englewood, FL...4-7 ft
East of Mexico Beach, FL to Indian Pass, FL...3-5 ft
Englewood, FL to Flamingo, FL...3-5 ft
Charlotte Harbor...3-5 ft

The deepest water will occur along the immediate coast near and to
the east of the landfall location, where the surge will be
accompanied by large and dangerous waves. Surge-related flooding
depends on the relative timing of the surge and the tidal cycle,
and can vary greatly over short distances. For information
specific to your area, please see products issued by your local
National Weather Service forecast office.

For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_at4.shtml?peakSurge.

WIND: Hurricane conditions are expected within the hurricane warning
area this evening. Tropical storm conditions are occurring in the
southern and central Florida, and these conditions are expected to
spread northward across the tropical storm warning areas in the
Southeastern U.S. through early Friday. Strong, damaging winds,
especially in gusts, will likely penetrate as far inland as the
higher terrain of the southern Appalachians.

RAINFALL: Over portions of the Southeastern U.S. into the Southern
Appalachians, Helene is expected to produce total rain accumulations
of 6 to 12 inches, with isolated totals around 20 inches. This
rainfall will likely result in catastrophic and potentially
life-threatening flash and urban flooding, along with significant
river flooding. Numerous significant landslides are expected in
steep terrain across the southern Appalachians.

For a complete depiction of forecast rainfall associated with
Hurricane Helene, please see the National Weather Service Storm
Total Rainfall Graphic, available at
hurricanes.gov/graphics_at4.shtml?rainqpf and the Flash Flood Risk
graphic at hurricanes.gov/graphics_at4.shtml?ero.

this storm, see the companion storm summary at WBCSCCNS4 with the
WMO header ACUS44 KWBC or at the following link:
www.wpc.ncep.noaa.gov/discussions/nfdscc4.html.

TORNADOES: The risk for several tornadoes continues through
tonight over much of Florida, southeast Georgia, central and
southern South Carolina, and southern North Carolina. The tornado
risk will continue Friday across the Carolinas and southern
Virginia.

SURF: Swells generated by Helene will affect much of Florida and
the coasts of Georgia and the Carolinas during the next couple of
days. These swells are likely to cause life-threatening surf and
rip current conditions. Please consult products from your local
weather office.

Hurricane Helene Discussion Number 14
NWS National Hurricane Center Miami FL AL092024
500 PM EDT Thu Sep 26 2024

Helene has rapidly intensified today while nearing landfall in the
Florida Big Bend. Doppler radar and aircraft data indicate that the
eyewall is now completely closed and the eye has become more
circular and is clearing out. The aircraft data also indicated
that the inner core has contracted significantly today while the
tropical-storm-force winds have expanded. Based on all of the data,
the initial intensity is set at 110 kt. The latest minimum pressure
based on the aircraft data is around 951 mb. Tropical-storm-force
winds are occurring across portions of west-central and southwestern
Florida, and conditions are expected to deteriorate rapidly in the
hurricane warning area during the next several hours. It should be
emphasized that Helene is at the upper bound of hurricanes in
terms of storm size and impacts are and will occur well away
from the center.

The large hurricane is now accelerating north-northeastward, with
the latest initial motion estimated to be 025/20 kt. This general
motion is expected to continue, taking the core of the major
hurricane to the Florida Big Bend later this evening. After
landfall, a turn to the north over Georgia is expected late tonight
and early Friday, followed by a slowdown or a complete stall over
the Tennessee Valley late Friday and Saturday when Helene merges
with a mid- to upper-level low.

The hurricane has intensified by 30 kt since sunrise and given the
conducive environmental conditions and contracting inner core, it
seems likely that Helene will be at or very near category 4 strength
when it makes landfall in the Florida Big Bend this evening.
The fast forward speed when Helene moves inland will result in a
far inland penetration of strong winds over parts of the
southeastern United States, including strong gusts over the higher
terrain of the southern Appalachians. Accordingly, a
higher-than-normal gust factor is indicated in the official forecast
while Helene is inland.

KEY MESSAGES:

1. A catastrophic and deadly storm surge will occur along portions
of the Florida Big Bend coast, where inundation could reach as high
as 20 feet above ground level, along with destructive waves. If
you live in this area and were told to evacuate by local officials,
your opportunity to do so is almost over. There is also a danger
of life-threatening storm surge along the remainder of the west
coast of the Florida Peninsula.

2. Potentially catastrophic hurricane-force winds are expected
within the eyewall of Helene and will spread inland over portions
of northern Florida and southern Georgia when Helene makes landfall
in the Florida Big Bend region this evening. Persons in these
areas should be prepared to take shelter in the interior portion of
a well-built structure and remain sheltered until after hazardous
conditions pass. You may need to remain sheltered after the storm
due to downed trees and power lines, as well as flooding, in the
area.

3. Damaging wind gusts will penetrate well inland over portions of
Georgia and the Carolinas tonight, particularly over the higher
terrain of the southern Appalachians. Residents in these areas
should be prepared for the possibility of long-duration power
outages. If you use a generator after the storm, be sure it is
placed outside at least 20 feet away from doors, windows, and
garages to avoid deadly carbon monoxide poisoning.

4. Catastrophic and life-threatening flash and urban flooding,
including numerous significant landslides, is expected across
portions of the southern Appalachians through Friday. Considerable
to locally catastrophic flash and urban flooding is likely for
northwestern and northern Florida and the Southeast through Friday.
Widespread significant river flooding and isolated major river
flooding are likely.

Radar data continues to suggest that the eyewall is increasingly dominating the secondary band that had been preventing consolidation of the inner core wind field. Simultaneously, subsidence warming in the eye is strengthening leading to a clearer eye on IR imagery. This probably means max winds in #Helene's eyewall are increasing further, unfortunately.
