based on satellite imagery, weather observations, radar, and
meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through

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

A surface trough extends from 07N77W to 05N87W to 05N100W. The 
ITCZ extends from 05N100W to 07N120W to 06N135W. The ITCZ resumes
W of a surface trough near 06N138W to beyond 06N140W. Scattered 
moderate convection is from 05N to 14N between 116W and 138W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Locally fresh NW winds are over the central and southern Gulf of
California. Elsewhere, gentle to moderate NW to N winds prevail 
across most of the offshore waters with 1024 mb high near 
29N132W.

Offshore high pressure will prevail west of the region through
the weekend and into early next week. Moderate NW winds off Baja
California and over the N Gulf of California will diminish today.
Long period NW swell over the Baja California offshore waters 
will gradually decay through today. Fresh to strong N winds will
be over the Gulf of Tehuantepec today and Sat. Another round of 
fresh to strong winds will start over the Gulf of Tehuantepec 
Thu.

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

High pressure building north of the area will support fresh to 
strong NE to E winds over the Papagayo region from Fri night through
Sun evening. Moderate N winds over the Gulf of Panama region 
will strengthen to fresh to strong Fri night through Sun 
evening.

REMAINDER OF THE AREA...

A persistent surface trough from 05N137W to 14N136W has
fresh winds within 240 nm of the axis. Scattered moderate 
convection is also over the area. Seas are running 8-10 ft. The 
trough is likely to weaken and drift slowly westward, passing 
west of 140W by Fri night. 

Elsewhere, seas 12-15 ft in NW swell continue over the NW corner
near 30N140W. A large area W of 105W has moderate to fresh winds
with 8-12 ft NW swell. This swell will persist though the
weekend. A weakening cold front will move into the far NW waters
Sat, then stall and dissipate Sat night into Sun.
