Tropical Weather Discussion for the eastern Pacific Ocean from
the Equator to 32N, east of 140W. The following information is
based on satellite imagery, weather observations, radar, and
meteorological analysis.

Based on 0000 UTC surface analysis and satellite imagery through
0215 UTC.

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

The ITCZ extends from 06N89W to 03N115W to beyond 05N140W. 
Scattered moderate convection is noted from 03N to 08N between 
89W and 103W and from 03N to 08N between 133W and 140W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A cold front is approaching the west coast of Baja California
Norte this evening. Moderate NW winds are occurring to the south
and east of the front, with fresh NW winds behind it. Mainly
gentle winds are occurring off the west coast of mainland Mexico
and in the Gulf of California. Seas range from 3 to 6 ft, except
1 to 2 ft in the Gulf of California. 

The cold front will weaken tonight as it cross Baja California
and enters the northern Gulf of California, then dissipate Tue
over the central Gulf of California. Winds behind the front in
the northern Gulf of California will strengthen to strong, with 
some westerly near-gale force winds possible late tonight and
early Tue. Winds will then slowly subside into mid-week. NW swell
will impact waters offshore Baja California Tue and Wed, making
seas of 8 to 10 ft.

Looking ahead, gale force gap winds are likely to develop in the
Gulf of Tehuantepec Fri, as high pressure builds south into the
western Gulf of Mexico.

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

Moderate to fresh NE to E winds are noted within and downstream 
of the Papagayo region and Gulf of Panama. Light to gentle winds 
prevail elsewhere. Sea heights range from 4 to 6 ft. Fresh to
locally strong NE winds will pulse across the Papagayo region 
through Wed, with highest winds expected during the overnight 
hours. Seas associated with these winds will be 5 to 7 ft. Fresh 
north winds in the Gulf of Panama will pulse again Tue night. 
Light to gentle winds, with seas in the 3 to 6 ft range, will 
prevail elsewhere into late week.

REMAINDER OF THE AREA...

Moderate to fresh trades are occurring N of the ITCZ and S of
20N, with seas of 7 to 9 ft. A cold front extends from 31N115W to
25N130W to 26N140W. Fresh NE winds prevail to the N of this
front. This weakening front will continue moving east across the
waters north of 25N through Tue, then dissipate. Large NW swell
associated with this front is inducing seas of 8 to 12 ft N of
25N and W of 120W. This swell will move through the northern 
waters through Tue night while slowly subsiding. Another cold 
front will enter the NW waters early Wed. Some fresh to strong SW
winds are possible ahead of the front N of 27N and W of 130W. 
This front will usher in another set of NW swell into the NW 
waters, peaking near 13 ft on Thu.
