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

Based on 1200 UTC surface analysis and satellite imagery through

...SPECIAL FEATURE...

The remnant low of Tropical Storm Xavier remains a well defined 
low level cloud swirl near 19N108.5W at 1200 UTC , moving 
westward at 8 kt. Minimal gale force winds continue within 45 nm 
across the northern semicircle. Winds will diminish below gale 
force later this morning as the remnant low continues to move 
due west and spin down. This remnant low is expected to move 
across Las Islas Revillagigedo this evening.

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

The monsoon trough extends from 08.5N74W to low pres near 
07.5N96W to 08N113W. The ITCZ extends from 11N123W to beyond 
11N140W. Widely scattered moderate convection is noted within 
180 nm S of the trough between 80W and 89W, and also within 270 
nm across the N semicircle of low pres near 15N119.5W.

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 

Please see special features section above for more on gales
associated to the remnant low of Tropical Storm Xavier.

A ridge extending from 1026 mb high pressure near 39N140W to 
just SW of Baja California Sur will continue to dominate the 
area the next several days. A light to gentle anticyclonic flow 
around this ridge will prevail west of the Baja California 
Peninsula. Seas of 4 to 7 ft in NW swell will generally prevail. 

Gulf of California: Variable, mainly gentle southerly winds are 
expected across most of the Gulf through late Thu. High pressure 
will build over the Great Basin region later this week. This 
will support fresh to strong northerly winds over the northern 
gulf Fri through Sat morning.

Gulf of Tehuantepec: A cold front will shift across the Gulf of
Mexico later this week. The cold front is currently forecast to 
reach the Bay of Campeche by the start of the weekend. This will
help usher in the next gap wind event. Winds are forecast to 
build to near gale force late Saturday, with the possibility of 
reaching minimal gale force Saturday night. 

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

Light to gentle winds are forecast north of the monsoon trough. 
Gentle to moderate southwest monsoon flow is expected south of 
the monsoon trough through the middle of the week before
diminishing. Long period SW swell will push north of the equator
into the waters off Panama and Costa Rica tonight into Wed.
   
REMAINDER OF THE AREA...  

Moderate to locally fresh winds prevail N of the ITCZ and west 
of 130W, while moderate southeasterly flow is noted south of the 
ITCZ. Seas 8 to 9 ft, in N to NE swell, are noted over the 
waters NW of a line from 30N122W TO 29N128W TO 29N135W TO 
25N140W. Seas over this area will begin to subside tonight. A 
new pulse of northerly swell will propagate into the northern 
waters Wednesday, with seas building to 8 ft N of 28N between 
120W and 131W.
