TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
530 PM EDT MON SEP 10 2007

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

THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON TROPICAL
DEPRESSION GABRIELLE...LOCATED ABOUT 260 MILES SOUTH OF NANTUCKET
MASSACHUSETTS.

A BROAD AREA OF LOW PRESSURE...ASSOCIATED WITH A TROPICAL WAVE...IS
LOCATED ABOUT MIDWAY BETWEEN THE CAPE VERDE ISLANDS AND THE LESSER
ANTILLES AND IS ACCOMPANIED BY A LARGE AREA OF SHOWERS AND
THUNDERSTORMS.  THIS SYSTEM IS SLOWLY BECOMING BETTER ORGANIZED AND
COULD DEVELOP INTO A TROPICAL DEPRESSION WITHIN A DAY OR TWO AS IT
MOVES WESTWARD TO WEST-NORTHWESTWARD AT 10 TO 15 MPH.

SHOWER AND THUNDERSTORM ACTIVITY OVER THE LESSER ANTILLES AND THE
EXTREME EASTERN CARIBBEAN SEA IS ASSOCIATED WITH A TROPICAL WAVE.  
SURFACE PRESSURES ARE NOT FALLING IN THE AREA...AND SIGNIFICANT
DEVELOPMENT OF THIS SYSTEM IS NOT ANTICIPATED AS IT MOVES
WEST-NORTHWESTWARD AT ABOUT 15 MPH.  

SURFACE OBSERVATIONS INDICATE THAT A BROAD AREA OF LOW PRESSURE IS
LOCATED OVER THE WESTERN GULF OF MEXICO.  ALTHOUGH THE ASSOCIATED
CLOUDINESS AND THUNDERSTORMS ARE DISORGANIZED AT THIS TIME...
UPPER-LEVEL WINDS COULD BECOME A LITTLE MORE FAVORABLE FOR
DEVELOPMENT AS THE SYSTEM MOVES SLOWLY WESTWARD.

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