NWS National Hurricane Center Miami FL
1005 UTC Sat Nov 28 2020

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 0600 UTC surface analysis and satellite imagery through
0900 UTC.

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

The monsoon trough axis extends from 09N83W to 07N99W to 11N118W
to 09N123W. The ITCZ continues from 09N123W to 08N130W to beyond
08N140W. Scattered moderate convection is noted from 06N to 09N 
between 87W and 99W, and from 06N to 10N between 111W and 119W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A broad ridge prevails west of Baja California. Fresh to strong 
NW winds in the Gulf of California are expected to continue 
into tonight, with seas expected to build to 6-7 ft from these 
winds. Gentle to moderate northerly winds will prevail west of 
the Baja California peninsula, with stronger NE winds shooting 
through gaps between the higher elevations of Baja California, 
and extending up to 90 nm offshore.

Large NW swell west of Baja California, with seas to near 10 ft,
will gradually subside through tonight, and fall below 8 ft by 
early Sun. 

A strong cold front expected to move across the Gulf of Mexico 
this weekend will induce gale force winds across Tehuantepec 
beginning Mon afternoon. Winds are then expected to diminish 
below gale force on Tue.

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

Fresh NE to E winds will pulse each night in the Papagayo region.
Moderate S to SW winds are expected elsewhere south of 10N. 
Moderate cross-equatorial swell in the waters west of Central 
America will subside Sun through Tue. 

REMAINDER OF THE AREA...

A ridge extends across the waters west of Baja California to 
near the Revillagigedo Islands. The gradient between the ridge 
and lower pressures associated with the convergence zone is 
supporting moderate to fresh trade winds north of 10N and west 
of 120W. Seas are generally 6-8 ft across this area. The NW 
swell will continue to spread southeastward and slowly decay 
through the weekend. Looking ahead, another pulse of NW swell is 
forecast to reach 30N140W tonight through Sun night, with larger
NW swell moving southeast into the area next week.
