SPECIAL TROPICAL DISTURBANCE STATEMENT
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 RAIN BANDS 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.
