NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
435 AM EDT THU SEP 25 2008
A WELL-DEFINED EXTRATROPICAL LOW PRESSURE SYSTEM CENTERED ABOUT 225
MILES SOUTHEAST OF THE SOUTH CAROLINA-NORTH CAROLINA BORDER IS
MOVING WEST-NORTHWESTWARD AT 5 TO 10 MPH. SHOWERS AND THUNDERSTORMS
ARE GRADUALLY BECOMING BETTER ORGANIZED AND THIS SYSTEM COULD
DEVELOP INTO A SUBTROPICAL OR TROPICAL CYCLONE BEFORE THE SYSTEM
MOVES INLAND ALONG THE ALONG THE SOUTHEASTERN U.S. COAST ON FRIDAY.
REGARDLESS OF WHETHER OR NOT THIS SYSTEM BECOMES A SUBTROPICAL OR
TROPICAL CYCLONE... STRONG WINDS...COASTAL FLOODING...HIGH SURF...
AND DANGEROUS RIP CURRENTS WILL CONTINUE ALONG PORTIONS OF THE
SOUTHEASTERN AND MID-ATLANTIC U.S. COASTAL REGIONS DURING THE NEXT
COUPLE OF DAYS. OUTER RAINBANDS CONTINUE TO SPREAD ONSHORE THE
NORTH CAROLINA COAST THIS MORNING...AND BUOY AND SHIP REPORTS
INDICATE WINDS IN EXCESS OF 50 MPH ARE OCCURRING MORE THAN 100
MILES FORM THE CENTER. AN AIR FORCE RESERVE UNIT RECONNAISSANCE
AIRCRAFT SCHEDULED TO INVESTIGATE THE SYSTEM LATER THIS MORNING
WILL PROVIDE BETTER INFORMATION ON ITS STRUCTURE AND INTENSITY.
INTERESTS ALONG THE U.S. EAST COAST FROM THE CAROLINAS NORTHWARD TO
MID-ATLANTIC REGION SHOULD CLOSELY MONITOR STATEMENTS FROM THEIR
LOCAL NATIONAL WEATHER SERVICE FORECAST OFFICES...AND ALSO HIGH
SEAS FORECASTS ISSUED BY THE OCEAN PREDICTION CENTER IN WASHINGTON
D.C. FOR ADDITIONAL INFORMATION AND WARNINGS.
ANOTHER LOW PRESSURE SYSTEM OF TROPICAL ORIGIN CENTERED ABOUT 180
MILES EAST-NORTHEAST OF THE TURKS AND CAICOS ISLANDS IS MOVING
NORTHWARD AT AROUND 10 MPH. SATELLITE IMAGERY INDICATES
THUNDERSTORM ACTIVITY HAS CONTINUED TO INCREASE AND BECOME A LITTLE
BETTER ORGANIZED THIS MORNING. UPPER-LEVEL WINDS ARE EXPECTED TO
GRADUALLY BECOME A LITTLE MORE CONDUCIVE FOR A TROPICAL DEPRESSION
OR A TROPICAL STORM TO DEVELOP DURING THE NEXT DAY OR SO. REPORTS
FROM NEARBY SHIPS INDICATE SUSTAINED WINDS OF 30 TO 35 MPH NORTH OF
THE CENTER. A NOAA RECONNAISSANCE AIRCRAFT IS CURRENTLY ENROUTE TO
PROVIDE A BETTER ESTIMATE OF THE LOCATION AND INTENSITY OF THE LOW.
AS THIS WEATHER SYSTEM MOVES FARTHER NORTH TODAY...THE THREAT FOR
HEAVY RAINFALL AND ASSOCIATED FLOODS AND MUD SLIDES OVER
HISPANIOLA...PUERTO RICO...AND THE VIRGIN ISLANDS WILL GRADUALLY
SUBSIDE.
