800 AM EDT SAT SEP 11 2010

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

THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON TROPICAL
STORM IGOR...LOCATED ABOUT 915 MILES WEST OF THE CAPE VERDE
ISLANDS.

SHOWERS AND THUNDERSTORMS HAVE INCREASED IN ASSOCIATION WITH A BROAD
AREA OF LOW PRESSURE LOCATED OVER THE EASTERN CARIBBEAN SEA. 
ENVIRONMENTAL CONDITIONS APPEAR TO BE CONDUCIVE FOR DEVELOPMENT...
AND A TROPICAL DEPRESSION COULD FORM AS THE SYSTEM MOVES WESTWARD
INTO THE CENTRAL AND WESTERN CARIBBEAN SEA. THERE IS A HIGH
CHANCE...60 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE
DURING THE NEXT 48 HOURS.

A VIGOROUS TROPICAL WAVE LOCATED NEAR THE WEST COAST OF AFRICA IS
SHOWING SOME SIGNS OF ORGANIZATION.  SOME DEVELOPMENT OF THIS
SYSTEM IS POSSIBLE OVER THE NEXT COUPLE OF DAYS AS IT MOVES TO THE
WEST OR WEST-NORTHWEST AT 10 TO 15 MPH.  THERE IS A MEDIUM
CHANCE...30 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE
DURING THE NEXT 48 HOURS.  

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