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

A BROAD AREA OF LOW PRESSURE LOCATED OVER THE CENTRAL TROPICAL
ATLANTIC ABOUT MIDWAY BETWEEN THE LESSER ANTILLES AND AFRICA IS
PRODUCING A LARGE AREA OF CLOUDINESS AND THUNDERSTORMS.
ENVIRONMENTAL CONDITIONS ARE FAVORABLE FOR GRADUAL DEVELOPMENT OF
THIS LARGE DISTURBANCE OVER THE NEXT FEW DAYS AS IT MOVES
WESTWARD AT 5 TO 10 MPH. THIS SYSTEM HAS A LOW CHANCE...20
PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.

AN ELONGATED AREA OF LOW PRESSURE IS LOCATED ABOUT 300 MILES SOUTH
OF THE CAPE VERDE ISLANDS. THIS SYSTEM HAS CHANGED LITTLE AND
DEVELOPMENT...IF ANY...SHOULD BE SLOW TO OCCUR AS IT INTERACTS WITH
A LARGER DISTURBANCE TO ITS SOUTHWEST.  THIS SYSTEM HAS A LOW
CHANCE...10 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS AS MOVES WEST-NORTHWESTWARD AT 10 TO 15 MPH.

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