meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through

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

The monsoon trough extends from 09N85W to 07.5N96W to 10N112W to
09N118W. The ITCZ continues from 09N118W to 05N140W. Scattered 
moderate isolated strong convection is noted from 01N to 10N 
between 90W and 110W, and from 05N to 09N between 125W and 140W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Strong northwest winds over the central Gulf of California will
diminish early today. Moderate to fresh winds prevail west of the
Baja California peninsula. Gentle to moderate winds prevail 
elsewhere over the open waters off Mexico. Seas are in the 4-5 
ft range in a mix of northwest and south swell over the open 
waters off Mexico.

For the forecast, high pressure west of the region will support 
moderate to fresh winds off Baja California. Farther south, 
slight to moderate seas will build today as a set of southerly 
swell arrives. Additional southerly swell will further build seas
slightly late Fri and Sat over the waters south of the Gulf of 
Tehuantepec region. 

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL 
AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR...

Fresh to strong gap winds prevail over the Gulf of Papagayo, with
moderate to fresh winds over the Gulf of Panama. Gentle to 
moderate winds persist elsewhere. Seas are in the 4-6 ft range in
lingering southerly swell.

For the forecast, gentle to moderate winds will persist across 
the region, with subsiding southerly swell. Fresh to strong gap 
winds across the Gulf of Papagayo will diminish this morning. 
Additional southerly swell will move into the region through 
early Thu, then begin to subside. 

REMAINDER OF THE AREA...

High pressure of 1025 mb is centered near 36N128W. The pressure 
gradient between the area of high pressure and lower pressure in 
the vicinity of the ITCZ is supporting moderate winds north of 
the ITCZ, with seas in the 4-7 ft range. Light to gentle winds 
and seas in the 5-7 ft range prevail elsewhere. High pressure 
will continue north of the area with these general conditions 
prevailing.
