NWS National Hurricane Center Miami FL
120 UTC Thu Jan 2 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
0100 UTC.

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

The monsoon trough extends from 07N77W to low pressure near 
07N92W to 08N115W to 07N125W. The ITCZ continues from 07N125W to 
beyond 08N140W. Scattered moderate convection is noted from 06N
to 09N between 92W and 96W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Low pressure located this evening over the southern Gulf of
California will weaken and move inland tonight. A cold front
located from Cabo Corrientes to about 600 km S of the
Revillagigedo Islands will move SE and dissipate Thu. Fresh N
winds behind the front in the waters offshore Baja California and
portions of the Gulf of California will gradually diminish as 
the front dissipates.

Large, long period NW swell continues to propagate SE in offshore
Baja California waters this evening, and will reach the
Revillagigedo Islands overnight, then continue to off much of the
waters along the Pacific coast of Mexico through the week. Seas
of 9 to 12 ft will only slowly subside through Fri and dangerous
surf conditions are expected. A strong cold front moving into 
the SW Gulf of Mexico Thu and Fri will induce gale force winds 
over and downstream of Gulf of Tehuantepec this weekend.

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

Fresh Gulf of Papagayo region will diminish Thu. Long period NW 
swell will move SE across the offshore waters Fri through Sat 
night, with fresh to strong winds gap winds resuming across the 
Gulf of Papagayo region Sat night. Elsewhere, gentle to moderate 
S to SW flow will continue across the offshore waters of Costa 
Rica, Panama, Colombia, and Ecuador through Sun.

REMAINDER OF THE AREA...

High pressure of 1033 mb is centered near 33N137W, with ridge 
ridge axis extending SE into the northern waters, supporting 
fresh to strong trade winds N of 09N and W of 115W. Seas of up to
12 feet are also continuing in this region. Gentle to moderate 
winds will persist elsewhere across the region into Thu. Large, 
very long period NW swell over NW waters will sweep SE the next 
few days, resulting in seas greater than 12 ft north of 10N and 
west of 130W persisting into Thu night. Wave heights will 
gradually subside there by this weekend.
