Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 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 0000 UTC surface analysis and satellite imagery through
0300 UTC.

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

The monsoon trough axis extends from 09N79W to 07N98W to
09N108W. The ITCZ continues from 09N108W to 11N125W to beyond
10N140W. Scattered moderate isolated strong convection is noted
from 05N to 09N between 78W and 97W, and from 07N to 11N between
108W and 118W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A broad ridge prevails west of Baja California. Fresh to strong
NW winds are north of 25N in the Gulf of California. Fresh to
strong NW winds will prevail in the central Gulf of California
through Sat, 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 locally strong NE winds
shooting through the gaps between the higher elevations of Baja
and extending 90 nm offshore.

Large NW swell is impacting the waters west of Baja California,
with seas 8 ft or greater over these waters. Seas are peaking
near 10 ft west of Baja California Norte. Seas will gradually
subside through Sat evening, 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. 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 sone is
supporting moderate to fresh trade winds north of 10N and west
of 120W. Seas are generally 6-9 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 Sat night through Sun night, with
larger NW swell moving southeast into the area next week.
