100 AM EST MON NOV 21 2011

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

1. A BROAD LOW PRESSURE SYSTEM LOCATED ABOUT 850 MILES NORTHEAST OF THE
LEEWARD ISLANDS CONTINUES TO PRODUCE A LARGE AREA OF CLOUDINESS...
SHOWERS AND A FEW THUNDERSTORMS MAINLY TO THE NORTH AND EAST OF ITS
CENTER. THIS SYSTEM IS FORECAST TO STRENGTHEN AND PRODUCE
GALE-FORCE WINDS OVER THE NEXT COUPLE OF DAYS...AND IT IS POSSIBLE

BEFORE IT MOVES OVER COOLER WATER. THIS SYSTEM HAS A MEDIUM
CHANCE...40 PERCENT...OF BECOMING A SUBTROPICAL CYCLONE DURING THE
NEXT 48 HOURS AS IT MOVES NORTH-NORTHEASTWARD AT 10 TO 15 MPH. 
ADDITIONAL INFORMATION ON THIS LARGE WEATHER SYSTEM CAN BE FOUND IN
HIGH SEAS FORECASTS ISSUED BY THE NATIONAL WEATHER SERVICE...UNDER
AWIPS HEADER NFDHSFAT1 AND WMO HEADER FZNT01 KWBC.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
