TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
200 AM EDT SAT JUL 30 2011

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

THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON RECENTLY
DOWNGRADED TROPICAL DEPRESSION DON LOCATED ABOUT 40 MILES SOUTH OF
CORPUS CHRISTI TEXAS. 

SHOWERS AND THUNDERSTORMS HAVE BECOME MORE CONCENTRATED IN
ASSOCIATION WITH A LARGE LOW PRESSURE SYSTEM LOCATED ABOUT 1000
MILES EAST OF THE WINDWARD ISLANDS. SURFACE PRESSURES ARE VERY LOW
IN THE AREA...AND ENVIRONMENTAL CONDITIONS APPEAR FAVORABLE FOR A
TROPICAL DEPRESSION TO FORM OVER THE NEXT COUPLE OF DAYS.  THIS
SYSTEM HAS A HIGH CHANCE...70 PERCENT...OF BECOMING A TROPICAL
CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES WEST-NORTHWESTWARD AT
15 TO 20 MPH.   

A TROPICAL WAVE APPROACHING EASTERN HONDURAS AND NICARAGUA IS
PRODUCING DISORGANIZED SHOWER AND THUNDERSTORM ACTIVITY.  THIS
SYSTEM WILL LIKELY BRING LOCALLY HEAVY RAINFALL TO PORTIONS OF
CENTRAL AMERICA THROUGH THE WEEKEND AS IT MOVES WESTWARD AT 10 TO
15 MPH.  HOWEVER...NO SIGNIFICANT DEVELOPMENT IS EXPECTED DUE TO
INTERACTION WITH LAND.   THIS SYSTEM HAS A LOW CHANCE...NEAR 0
PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.  

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