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

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

SATELLITE IMAGERY AND DATA FROM AN AIR FORCE RESERVE RECONNAISSANCE
AIRCRAFT INDICATE THE LOW PRESSURE SYSTEM CENTERED ABOUT 160 MILES
SOUTHWEST OF GRAND CAYMAN HAS CHANGED LITTLE THIS AFTERNOON.
ALTHOUGH ENVIRONMENTAL CONDITIONS ARE ONLY MARGINALLY CONDUCIVE FOR
DEVELOPMENT...CONDITIONS ARE EXPECTED TO BECOME SOMEWHAT MORE
FAVORABLE FOR A TROPICAL DEPRESSION TO FORM DURING THE NEXT DAY OR
SO. THERE IS A HIGH CHANCE...70 PERCENT...OF THIS SYSTEM BECOMING A
TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT DRIFTS TO THE SOUTH
OR SOUTHEAST.  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.
