TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
200 PM EDT SAT AUG 20 2011

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

THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON TROPICAL
STORM HARVEY...LOCATED ABOUT 35 MILES SOUTH OF BELIZE CITY BELIZE.

1. A LARGE TROPICAL WAVE IS LOCATED ABOUT 250 MILES EAST OF THE LESSER
ANTILLES...MOVING WESTWARD TO WEST-NORTHWESTWARD AT ABOUT 20 MPH. 
THIS SYSTEM SHOWS SIGNS OF ORGANIZATION AND SURFACE OBSERVATIONS
INDICATE THAT PRESSURES ARE LOW IN THE AREA.  HOWEVER...THERE IS NO
EVIDENCE OF A SURFACE CIRCULATION AT THIS TIME.  SLOW DEVELOPMENT
OF THIS SYSTEM IS LIKELY...AND A TROPICAL DEPRESSION COULD FORM AT
ANY TIME OVER THE NEXT COUPLE OF DAYS.  THIS SYSTEM HAS A HIGH
CHANCE...90 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS.  INTERESTS IN THE LESSER ANTILLES...THE VIRGIN
ISLANDS...PUERTO RICO...AND HISPANIOLA SHOULD MONITOR THE PROGRESS
OF THIS DISTURBANCE.  LOCALLY HEAVY RAIN AND GUSTY WINDS ARE LIKELY
OVER THE LESSER ANTILLES LATER TODAY THROUGH SUNDAY...OVER THE
VIRGIN ISLANDS AND PUERTO RICO BY SUNDAY NIGHT...AND OVER HISPANIOLA
BY MONDAY.  AN AIR FORCE RESERVE HURRICANE HUNTER AIRCRAFT IS EN
ROUTE TO INVESTIGATE THIS SYSTEM.

2. A LARGE AND ELONGATED AREA OF LOW PRESSURE CENTERED JUST WEST OF THE
CAPE VERDE ISLANDS IS PRODUCING DISORGANIZED SHOWER AND
THUNDERSTORM ACTIVITY.  THE LOW IS MOVING WEST-NORTHWESTWARD AT
ABOUT 15 MPH INTO AN AREA OF UPPER-LEVEL WINDS AND SEA SURFACE
TEMPERATURES THAT ARE LESS CONDUCIVE FOR DEVELOPMENT.  THIS SYSTEM
HAS A MEDIUM CHANCE...30 PERCENT...OF BECOMING A TROPICAL CYCLONE
DURING THE NEXT 48 HOURS.  LOCALLY HEAVY RAINS AND GUSTY WINDS
SHOULD CONTINUE TO AFFECT PARTS OF THE CAPE VERDE ISLANDS THROUGH
THE REST OF TODAY.

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