TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
530 PM EDT SAT SEP 22 2007

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

THE TROPICS HAVE BECOME A LITTLE MORE ACTIVE THIS AFTERNOON WITH
SEVERAL AREAS OF DISTURBED WEATHER. SATELLITE IMAGES AND SURFACE
OBSERVATIONS INDICATE THAT A BROAD AREA OF LOW PRESSURE HAS FORMED
IN THE NORTHWESTERN CARIBBEAN SEA...AND IS ACCOMPANIED BY A LARGE
AREA OF CLOUDINESS AND THUNDERSTORMS. THE LOW IS EXPECTED TO MOVE
NORTHWESTWARD OVER THE YUCATAN PENINSULA TONIGHT. UPPER-LEVEL WINDS
ARE FAVORABLE FOR SLOW DEVELOPMENT OF THIS SYSTEM AFTER IT EMERGES
OVER THE GULF OF MEXICO ON SUNDAY.

SATELLITE IMAGES INDICATE THAT THE NON-TROPICAL LOW LOCATED ABOUT
825 MILES WEST-SOUTHWEST OF THE AZORES HAS BECOME A LITTLE BETTER
ORGANIZED. THIS SYSTEM COULD BECOME A TROPICAL OR A SUBTROPICAL
CYCLONE BEFORE IT MOVES NORTHEASTWARD OVER THE OPEN ATLANTIC IN A
COUPLE OF DAYS. 

THE AREA OF DISTURBED WEATHER CENTERED ABOUT 900 MILES EAST OF THE
WINDWARD ISLANDS IS ASSOCIATED WITH A WESTWARD MOVING TROPICAL
WAVE. THERE ARE SOME INDICATIONS THAT THE SYSTEM HAS BECOME A
LITTLE BETTER ORGANIZED THIS AFTERNOON BUT ADDITIONAL
DEVELOPMENT...IF ANY...SHOULD BE SLOW TO OCCUR.

THE BROAD AREA OF LOW PRESSURE LOCATED ABOUT 550 MILES SOUTH OF THE
CAPE VERDE ISLANDS REMAINS WELL-ORGANIZED.  THIS SYSTEM HAS THE
POTENTIAL TO BECOME A TROPICAL DEPRESSION AS IT MOVES WESTWARD AT
15 MPH DURING THE NEXT FEW DAYS.

AND YET ANOTHER AREA OF CLOUDINESS AND THUNDERSTORMS EXTENDS FROM 
NORTHEAST OF THE LEEWARD ISLANDS NORTHEASTWARD ACROSS THE ATLANTIC
FOR SEVERAL HUNDRED MILES. UPPER-LEVEL WINDS ARE HIGHLY UNFAVORABLE
FOR DEVELOPMENT.

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