TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
800 PM EDT WED SEP 22 2010

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

THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON TROPICAL
STORM LISA...LOCATED ABOUT 425 MILES WEST-NORTHWEST OF THE CAPE
VERDE ISLANDS.

AIRCRAFT DATA FROM NATIONAL SCIENCE FOUNDATION AND NASA RESEARCH
MISSIONS INDICATE THAT THE AREA OF LOW PRESSURE IN THE
SOUTH-CENTRAL CARIBBEAN SEA HAS BECOME A LITTLE BETTER DEFINED THIS
EVENING.  ENVIRONMENTAL CONDITIONS APPEAR FAVORABLE FOR DEVELOPMENT
AND THIS SYSTEM COULD BECOME A TROPICAL DEPRESSION DURING THE NEXT
DAY OR TWO AS IT MOVES WESTWARD AT 15 MPH TOWARD THE WESTERN
CARIBBEAN.  THERE IS A HIGH CHANCE...60 PERCENT...OF THIS SYSTEM
BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.  REGARDLESS
OF DEVELOPMENT...THIS SYSTEM HAS THE POTENTIAL TO PRODUCE HEAVY
RAINFALL OVER NORTHERN VENEZUELA AND COLOMBIA DURING THE NEXT DAY
OR SO...AND OVER PORTIONS OF CENTRAL AMERICA IN A COUPLE OF DAYS.

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