TROPICAL WEATHER OUTLOOK NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 200 PM EDT TUE SEP 1 2009

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

1. SATELLITE IMAGES INDICATE THAT A LOW PRESSURE AREA LOCATED ABOUT 260 MILES EAST OF THE LEEWARD ISLANDS COULD BE DEVELOPING A WELL-DEFINED SURFACE CENTER. AN AIR FORCE RESERVE RECONNAISSANCE AIRCRAFT IS CURRENTLY INVESTIGATING THE SYSTEM TO SEE IF A TROPICAL CYCLONE HAS FORMED. THIS SYSTEM COULD BECOME A TROPICAL DEPRESSION OR...MORE LIKELY...A TROPICAL STORM AT ANY TIME OVER THE NEXT COUPLE OF DAYS AS IT MOVES WEST-NORTHWESTWARD AT AROUND 10 MPH. THERE IS A HIGH CHANCE... GREATER THAN 50 PERCENT...OF TROPICAL CYCLONE FORMATION IN THIS AREA DURING THE NEXT 48 HOURS. INTERESTS IN THE NORTHERN LEEWARD ISLANDS...THE U.S. AND BRITISH VIRGIN ISLANDS...AND PUERTO RICO SHOULD MONITOR THE PROGRESS OF THIS SYSTEM. TROPICAL STORM WATCHES OR WARNINGS COULD BE REQUIRED FOR A PORTION OF THOSE AREAS THIS AFTERNOON.

2. A TROPICAL WAVE OVER THE FAR EASTERN ATLANTIC OCEAN JUST EAST OF THE CAPE VERDE ISLANDS CONTINUES TO SHOW SOME SIGNS OF ORGANIZATION. DEVELOPMENT...IF ANY...OF THIS SYSTEM IS EXPECTED TO BE SLOW TO OCCUR AS THE SYSTEM MOVES TO THE WEST OR WEST-NORTHWEST AT 10 TO 15 MPH. THERE IS A LOW CHANCE...LESS THAN 30 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.
