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

THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON HURRICANE
IRENE LOCATED ABOUT 55 MILES SOUTH OF GRAND TURK ISLAND.

SHOWERS AND THUNDERSTORMS NEAR A LARGE LOW PRESSURE SYSTEM LOCATED
ABOUT 925 MILES WEST-NORTHWEST OF THE CAPE VERDE ISLANDS HAVE
CHANGED LITTLE IN ORGANIZATION. WHILE 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 SOUTHEAST
OF THE CAPE VERDE ISLANDS IS PRODUCING A LIMITED AREA OF SHOWER
ACTIVITY.  HOWEVER...ENVIRONMENTAL CONDITIONS FAVOR SOME
DEVELOPMENT OF THIS LOW DURING THE NEXT SEVERAL DAYS.  THIS SYSTEM
HAS A LOW CHANCE...20 PERCENT...OF BECOMING A TROPICAL CYCLONE
DURING THE NEXT 48 HOURS AS IT MOVES TO THE WEST AT ABOUT 10 MPH.

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