GULF OF MEXICO...THE BIGGEST CONCERN OVER THE AREA IS T.S. 
ALBERTO THAT IS CENTERED OVER THE EXTREME NE GULF. ALBERTO IS 
FORECAST TO MOVE INLAND OVER THE FLORIDA BIG BEND AREA LATER 
TODAY. STRONGEST WINDS ARE FORECAST OVER THE EASTERN GULF WITH 
WINDS DECREASING OVER THE MIDDLE GULF TODAY. SEAS PEAKED AT 21 
FT AT BUOY 42036 AROUND 0100 UTC WITH THE CENTER PASSING JUST 
NORTH OF THIS BUOY AFTER MIDNIGHT. SEAS AT BUOY 42003 NEAR 
26N86W ARE CURRENTLY 11 FT. THIS IS MUCH HIGHER THAN THE NWW3
IS PREDICTING. 
 
WINDS AND SEAS FORECAST TO SLOWLY SUBSIDE OVER THE E GULF 
TONIGHT. WEAK TROUGH EXTENDING SW FROM THE TS WILL EXTEND 
SOUTH TO THE YUCATAN PENINSULA. THIS TROUGH WILL WEAKEN WED

CONDITIONS OFF THE NE FLORIDA AND GEORGIA COASTS. SWLY WINDS 
TO REMAIN STRONG WED...THEN DECREASE WED NIGHT. WEAK FRONT OR

PORTION OF THE OFFSHORE WATERS. RIDGE WEAKENS AND SINKS SOUTH
TO ALONG 26N.  WILL HAVE TO INCREASE SEAS A FEW FEET OVER THE
NW PART AS NWW3 NOT DOING WELL WITH THE TROPICAL SYSTEM.
