NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
800 PM EDT FRI SEP 10 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 620 MILES WEST OF THE CAPE VERDE
ISLANDS.

SHOWER AND THUNDERSTORM ACTIVITY IN ASSOCIATION WITH A LOW PRESSURE
SYSTEM NEAR THE WINDWARD ISLANDS REMAINS DISORGANIZED.  HOWEVER...
DATA FROM ANOTHER NATIONAL SCIENCE FOUNDATION RECONNAISSANCE
MISSION INTO AND AROUND THIS SYSTEM CONTINUE TO INDICATE A
WELL-DEFINED CIRCULATION. ENVIRONMENTAL CONDITIONS REMAIN CONDUCIVE
FOR A TROPICAL DEPRESSION TO FORM DURING THE NEXT COUPLE OF DAYS AS
THE SYSTEM MOVES SLOWLY WEST-NORTHWESTWARD. THERE IS A MEDIUM
CHANCE...50 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.
