BASED ON SATELLITE IMAGERY...WEATHER OBSERVATIONS...RADAR...AND 
METEOROLOGICAL ANALYSIS.

0300 UTC.                           

...SPECIAL FEATURE...

A STRONG COLD FRONT EXTENDS ACROSS THE FORECAST AREA FROM 
30N127W TO 19N140W. GALE FORCE WINDS TO 35 KT ARE CURRENTLY N OF 
26N WITHIN 120 NM E OF THE FRONT AND WINDS TO 40 KT N OF 25N W 
OF THE FRONT. SEAS ARE CURRENTLY REACHING 23 FT W OF THE FRONT. 
WINDS AHEAD OF THE FRONT WILL DIMINISH BELOW GALE FORCE BY FRI 
MORNING...AND WILL PERSIST W OF THE FRONT THROUGH SAT MORNING 
BEFORE DIMINISHING BELOW GALE FORCE. 

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...              

THE MONSOON TROUGH EXTENDS FROM 09N83W TO 07N92W TO 05N101W 
WHERE LOW LEVEL WINDS SUGGEST A TRANSITION TO ITCZ WHICH EXTENDS

AND THE TERRAIN ALONG THE COAST. THESE WILL DIMINISH OVERNIGHT 
AS THE HIGH WEAKENS IN ADVANCE OF THE APPROACHING FRONT. 
OTHERWISE...THE LOOSE PRESSURE GRADIENT BETWEEN THE WEAK HIGH 
PRESSURE AND ITCZ IS SUPPORTING GENTLE TO MODERATE WINDS OVER 
MUCH OF THE FORECAST AREA.
