TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
200 AM EDT SAT OCT 20 2012

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

1. A TROPICAL WAVE LOCATED SOUTH OF HISPANIOLA IS INTERACTING WITH AN
ELONGATED TROUGH OF LOW PRESSURE THAT EXTENDS FROM NICARAGUA
EASTWARD TO THE SOUTHERN WINDWARD ISLANDS. THIS BROAD DISTURBANCE
IS PRODUCING DISORGANIZED SHOWERS AND THUNDERSTORMS OVER MUCH OF
THE SOUTHWESTERN...CENTRAL...AND EASTERN CARIBBEAN SEA. HOWEVER...
ENVIRONMENTAL CONDITIONS ARE EXPECTED TO GRADUALLY BECOME MORE
CONDUCIVE OVER THE NEXT FEW DAYS FOR SOME DEVELOPMENT TO OCCUR
ACROSS THE CENTRAL OR SOUTHWESTERN CARIBBEAN SEA. THIS SYSTEM HAS 
A LOW CHANCE...20 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING
THE NEXT 48 HOURS AS IT MOVES SLOWLY WESTWARD.

2. A TROPICAL WAVE INTERACTING WITH AN UPPER-LEVEL LOW IS PRODUCING
WIDESPREAD CLOUDINESS AND SCATTERED THUNDERSTORMS OVER THE CENTRAL
TROPICAL ATLANTIC ABOUT 950 MILES EAST-NORTHEAST OF THE LEEWARD
ISLANDS. DEVELOPMENT...IF ANY...OF THIS DISTURBANCE SHOULD BE SLOW
TO OCCUR DUE TO UNFAVORABLE UPPER-LEVEL WINDS. THIS SYSTEM HAS A
LOW CHANCE...10 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS AS IT MOVES WEST-NORTHWESTWARD AT ABOUT 10 MPH.

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