TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
800 PM EDT WED OCT 20 2010

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

1. SHOWERS AND THUNDERSTORMS ASSOCIATED WITH THE LOW PRESSURE SYSTEM
CENTERED ABOUT 140 MILES SOUTH OF GRAND CAYMAN HAVE CHANGED LITTLE
IN ORGANIZATION DURING THE LAST SEVERAL HOURS.  UPPER-LEVEL WINDS
ARE FORECAST TO BECOME MORE CONDUCIVE FOR DEVELOPMENT OVER THE NEXT
DAY OR TWO...AND A TROPICAL DEPRESSION COULD FORM AT ANY TIME
TONIGHT OR THURSDAY.  THERE IS A HIGH CHANCE...80 PERCENT...OF THIS
SYSTEM BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT
MEANDERS SLOWLY.  INTERESTS IN THE NORTHWESTERN CARIBBEAN SEA
SHOULD CONTINUE TO MONITOR THE PROGRESS OF THIS DISTURBANCE. 
REGARDLESS OF DEVELOPMENT...HEAVY RAINFALL IS POSSIBLE OVER THE
CAYMAN ISLANDS AND JAMAICA DURING THE NEXT COUPLE OF DAYS.

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