TROPICAL STORM MATTHEW DISCUSSION NUMBER 5
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL152010
1100 AM EDT FRI SEP 24 2010

AN AIR FORCE PLANE INVESTIGATING MATTHEW THIS MORNING FOUND THAT THE
TROPICAL CYCLONE HAS NOT BECOME ANY STRONGER. EASTERLY SHEAR HAS
KEPT THE LOW-LEVEL CENTER NEAR THE NORTHEAST EDGE OF A ROUND BLOB
OF VERY DEEP CONVECTION AS INDICATED BY THE AIR FORCE PLANE AND
MICROWAVE DATA. SATELLITE INTENSITY ESTIMATES SUPPORT AN INITIAL
INTENSITY OF 45 KNOTS...BUT DATA FROM THE RECONNAISSANCE PLANE SO
FAR SUGGEST THAT THIS ESTIMATE COULD BE GENEROUS. MATTHEW ONLY HAS
12 HOURS OR LESS TO STRENGTHEN BEFORE LANDFALL...AND GIVEN THAT THE
ENVIRONMENT IS ONLY MARGINALLY FAVORABLE FOR INTENSIFICATION DUE TO
SHEAR...THE OFFICIAL FORECAST NO LONGER FORECAST MATTHEW TO BECOME
A HURRICANE.

THE CYCLONE HAS INCREASED ITS FORWARD SPEED AND THE BEST ESTIMATE OF
THE INITIAL MOTION IS TOWARD THE WEST OR 275 DEGREES AT 17 KNOTS.
MATTHEW IS EMBEDDED WITHIN A STRONG DEEP EASTERLY FLOW AND THERE IS
HIGH CONFIDENCE IN THE FORECAST THAT THE CYCLONE WILL CONTINUE
WESTWARD OVER CENTRAL AMERICA FOR THE NEXT DAY OR TWO. BEYOND TWO
DAYS...MODELS SHOW DIFFERENT SCENARIOS AND THE FORECAST BECOMES
HIGHLY UNCERTAIN. THE MOST LIKELY SCENARIO IS THAT THE MID-LEVEL
CENTER CONTINUES WESTWARD AND DISSIPATES...WHILE THE LOW-LEVEL
CIRCULATION WEAKENS AND BECOMES PART OF A NEARLY STATIONARY BROAD
AREA OF LOW PRESSURE OVER CENTRAL AMERICA. SUCH A WEATHER PATTERN
WOULD LIKELY PRODUCE DANGEROUS TORRENTIAL RAINS IN CENTRAL AMERICA
OVER THE NEXT FEW DAYS.

Matthew Racing Towards Central America...


Newly named T.S. Matthew is racing westward at 17 mph and shows no signs of slowing down or turning to the north. NHC has shifted their earlier track slightly to the south and west meaning Matthew will impact land sooner and stay over land longer...bad news for Honduras and Belize and the Yucatan, but good news for us. We finally have a real cold front coming that will drop the Southshore into the 60s for next week with 50s on the Northshore ! That should protect us from whatever is left of Matthew or any new system that might develop south of Cuba. Florida could see an extended period of heavy rains thru the weekend into next week...

Authorities on Colombia's Caribbean coast and the island of San Andres are preparing for the arrival of heavy weather due to tropical storm Matthew.
Even though the eye of the storm is staying north of the Caribbean islands of San Andres and Providencia, authorities expect heavy rains and squals to hit the islands and Colombia's northern coast on Friday and Saturday.
Authorities recommend tourists, fishermen and boat owners to consult the different port authorities before going to sea.
U.S. hurricane authorities are expecting Matthew to turn into a hurricane on Friday before hitting Honduras and continuing towards Belize and Mexico's Yucatan peninsula.

Matthew May Near Hurricane Strength by Nightfall

September 24, 2010, 8:22 AM EDT<cite>By Alex Morales and Brian K. Sullivan</cite>


Sept. 24 (Bloomberg) -- Tropical Storm Matthew may near hurricane strength later today before hitting the Nicaragua- Honduras border along its Caribbean coast and continuing on a course toward Belize and Mexico?s Yucatan peninsula.

Matthew?s winds increased to 50 miles (85 kilometers) an hour from 45 mph earlier today, the National Hurricane Center said in a website advisory at 6 a.m. Honduras time. A hurricane warning was in place from Puerto Cabezas in Nicaragua to Limon, Honduras, including offshore islands such as Roatan, indicating winds of at least 74 mph are expected within 36 hours.
?Matthew could be near hurricane strength before it moves close to Central America late today,? the Miami-based center said. ?The center of Matthew is expected to be near or over northeastern Nicaragua and eastern Honduras later today.?
Matthew helped push natural gas futures higher over concerns that the system may develop into a hurricane and threaten energy interests in the Gulf of Mexico, home to 31 percent of U.S. oil production and 10 percent of gas. The southern gulf also contains the Petroleos Mexicanos?s Cantarell oil field, Mexico?s largest.

....
The center?s track shows Matthew grazing Honduras?s east coast before striking Belize early Sunday, Sept. 26, then turning northwest into the tip of Guatemala and to Mexico?s Yucatan early Tuesday, Sept. 28, on a course toward the Gulf. The center has said repeatedly its long-range tracks can be off by several hundred miles. The center warned of heavy rainfall over portions of Nicaragua and Honduras of six to 15 inches in isolated areas, including life-threatening flash floods and possible landslides.

Tropical Storm Matthew Headed To Western Caribbean

Excerpt:

...CBS4 Meteorologist Lissette Gonzalez says this is a storm to closely monitor over the next few days because a few of the models take this system towards the Western Caribbean this weekend and then possibly on a northerly track towards the Florida Straits by the middle of next week. Other models take the system towards Central America where it's already dumping rain. Regardless of development, this system will produce heavy rainfall over portions of Central America...

Tropical Storm Matthew could be threat to Florida

BY CURTIS MORGAN

cmorgan@MiamiHerald.com

Excerpt:

...``There are a lot of variables involved that make this a complicated forecast,'' said Michael Lowry, a meteorologist at the center in West Miami-Dade County.
...

Some computer models, Lowry said, suggest the storm might split, with Matthew moving inland but a remnant left behind reforming into a new system. Lowry said the storm is too far off to get a solid handle on it, but the path should become more clear in coming days. For Florida, he said, it was a ``concern'' that many computer models predicted the system moving somewhere across the state...

Re: An area of low pressure over the south-central Caribbean sea has the potential to become a tropical depression

THUNDERSTORM ACTIVITY HAS CONTINUED TO INCREASE AND BECOME BETTER
ORGANIZED THIS MORNING IN ASSOCIATION WITH A VIGOROUS LOW PRESSURE
SYSTEM LOCATED OVER THE SOUTH-CENTRAL CARIBBEAN SEA. ENVIRONMENTAL
CONDITIONS ARE GRADUALLY BECOMING MORE FAVORABLE FOR DEVELOPMENT...
AND THIS DISTURBANCE COULD BECOME A TROPICAL DEPRESSION LATER TODAY
AS IT MOVES WESTWARD AT AROUND 15 MPH. AN AIR FORCE RESERVE
RECONNAISSANCE UNIT AIRCRAFT IS SCHEDULED TO INVESTIGATE THE SYSTEM
LATER THIS MORNING. THERE IS A HIGH CHANCE...80 PERCENT...OF THIS
SYSTEM BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.
REGARDLESS OF DEVELOPMENT...THIS DISTURBANCE HAS THE POTENTIAL TO
