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

Based on 0000 UTC surface analysis and satellite imagery through
0300 UTC. 

...TROPICAL WAVES...

The axis of a tropical wave is near 95W N of 08N. Convection
associated to this wave is S of 10N and discussed in the
ITCZ/monsoon trough section below. 

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

The monsoon trough extends from 07.5N78W to 09N86W to 09N114W. 
The ITCZ extends from 09N114W to 07N130W to beyond 06N140W. 
Scattered moderate convection is noted from 08N to 10N between
90W and 107W, and from 07N to 09N between 113W and 117W. 

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 

A ridge extends from 1033 mb high pressure west of California 
southeastward to near 18N105W. The ridge will prevail over this 
area the next few days. Mainly light to gentle anticyclonic flow
around this ridge will prevail west of the Baja California 
Peninsula, with seas of 4-6 ft in NW swell. 

Gulf of California: High pressure is building over the Great 
Basin region will help induce strong to near gale force 
northerly winds over the northern Gulf early Fri through Sat 
morning, with seas building to 10 ft. Winds will then diminish to
20 kt or less Sat.

Gulf of Tehuantepec: A cold front will shift across the Gulf of 
Mexico and reach the Bay of Campeche by Sat morning. This will 
help usher in the next gap wind event across Tehuantepec. Winds 
are forecast to increase briefly to near gale force late Sat
then diminish on Sun. A more significant gap wind event is 
expected by Tue of next week. 

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

Fresh to occasionally strong winds will pulse over the Gulf of 
Papagayo beginning Sat night. Otherwise, light to gentle winds 
are forecast north of the monsoon trough. Gentle to moderate 
southwest monsoon flow is expected south of the monsoon trough. 
   
REMAINDER OF THE AREA...  

Moderate to locally fresh NE to E winds prevail N of the ITCZ 
and west of 120W, while gentle to moderate E to SE flow is noted 
south of the ITCZ.
