TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
800 AM EDT MON SEP 13 2010

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

THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON HURRICANE
IGOR...LOCATED ABOUT 940 MILES EAST OF THE NORTHERN LEEWARD ISLANDS
...AND ON TROPICAL STORM JULIA...LOCATED ABOUT 85 MILES
WEST-SOUTHWEST OF THE SOUTHERNMOST CAPE VERDE ISLANDS.  

A TROUGH OF LOW PRESSURE OVER THE CENTRAL CARIBBEAN SEA CONTINUES TO
PRODUCE DISORGANIZED CLOUDINESS AND SHOWERS.  ENVIRONMENTAL
CONDITIONS APPEAR TO BE CONDUCIVE FOR SOME DEVELOPMENT DURING THE
NEXT COUPLE OF DAYS AS THE TROUGH MOVES WEST-NORTHWESTWARD AT
AROUND 15 MPH.  THERE IS A MEDIUM CHANCE...40 PERCENT...OF THIS
SYSTEM BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS. 
REGARDLESS OF DEVELOPMENT...LOCALLY HEAVY RAINFALL IS POSSIBLE OVER
PORTIONS OF HISPANIOLA...JAMAICA...CUBA...AND THE CAYMAN ISLANDS
DURING THE NEXT DAY OR TWO. THESE RAINS COULD CAUSE
LIFE-THREATENING FLASH FLOODS AND MUD SLIDES...ESPECIALLY IN
MOUNTAINOUS TERRAIN.  

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

PUBLIC ADVISORIES ON JULIA ARE ISSUED UNDER WMO HEADER WTNT32 KNHC
AND UNDER AWIPS HEADER MIATCPAT2. FORECAST/ADVISORIES ARE ISSUED
UNDER WMO HEADER WTNT22 KNHC AND UNDER AWIPS HEADER MIATCMAT2.
