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

THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON HURRICANE
IRENE LOCATED ABOUT 50 MILES WEST-SOUTHWEST OF GRAND TURK ISLAND.

SHOWERS AND THUNDERSTORMS ARE LIMITED IN ASSOCIATION WITH A
LARGE LOW PRESSURE SYSTEM LOCATED ABOUT 1000 MILES WEST-NORTHWEST
OF THE NORTHERN CAPE VERDE ISLANDS.  ALTHOUGH THE LOW IS MOVING
WEST-NORTHWESTWARD AT ABOUT 15 MPH TOWARD WARMER WATERS...
UPPER-LEVEL WINDS ARE BECOMING LESS FAVORABLE FOR DEVELOPMENT. THIS
SYSTEM HAS A LOW CHANCE...10 PERCENT...OF BECOMING A TROPICAL
CYCLONE DURING THE NEXT 48 HOURS.

A BROAD LOW PRESSURE AREA CENTERED A COUPLE HUNDRED MILES SOUTH OF
THE CAPE VERDE ISLANDS IS PRODUCING SCATTERED SHOWERS AND
THUNDERSTORMS.  ENVIRONMENTAL CONDITIONS APPEAR FAVORABLE FOR SOME
DEVELOPMENT OF THIS LOW DURING THE NEXT SEVERAL DAYS.  THIS SYSTEM
HAS A MEDIUM CHANCE...30 PERCENT...OF BECOMING A TROPICAL CYCLONE
DURING THE NEXT 48 HOURS AS IT MOVES WESTWARD AT 10 TO 15 MPH.

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