TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
200 AM 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 505 MILES WEST-NORTHWEST OF THE CAPE
VERDE ISLANDS.

SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A TROPICAL WAVE OVER THE
SOUTHEASTERN CARIBBEAN SEA HAVE CHANGED LITTLE IN ORGANIZATION
DURING THE PAST SEVERAL HOURS.  HOWEVER...ENVIRONMENTAL CONDITIONS
APPEAR CONDUCIVE FOR A TROPICAL DEPRESSION TO FORM DURING THE NEXT
COUPLE OF DAYS AS THE SYSTEM MOVES WESTWARD NEAR 15 MPH.  THERE IS
A MEDIUM CHANCE...50 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL
CYCLONE DURING THE NEXT 48 HOURS.  REGARDLESS OF DEVELOPMENT...
LOCALLY HEAVY RAINFALL AND GUSTY WINDS ARE LIKELY OVER THE WINDWARD
ISLANDS...THE NETHERLANDS ANTILLES...AND THE NORTHERN COASTS OF
VENEZUELA AND COLOMBIA DURING THE NEXT DAY OR TWO.  THESE RAINS
COULD CAUSE LIFE-THREATENING FLASH FLOODS AND MUD SLIDES.

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