Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Sun Jan 30 2022

Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 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
0230 UTC.

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

A surface trough extends from 07N78W to 05N83W to 05N95W. The 
ITCZ extends from 05N95W to 08N130W. Scattered moderate isolated
strong convection is noted from 10N to 20N between 125W and 140W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Fresh to strong winds prevail across the Gulf of Tehuantepec with
seas in the 8 to 9 ft range. Peak seas in the area of strong 
winds are 10 ft. Gentle to moderate N to NW winds prevail over 
the Gulf of California as well as west of the Baja California 
peninsula. Light to gentle winds prevail elsewhere over the open
waters off Mexico. Seas are in the 1-3 ft range over the Gulf of
California and 4-6 ft elsewhere.

For the forecast, fresh to strong winds will prevail in the Gulf
of Tehuantepec through Mon morning. Building high pressure west 
of California will produce fresh to strong NW winds and building 
seas over the waters west of Baja California Norte and the 
northern Gulf of California Tue night through Fri. The next gale-
force gap wind event in the Gulf of Tehuantepec is forecast to 
begin Fri.

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

Fresh to strong NE gap winds prevail across the Papagayo region 
with seas in the 6-8 ft range. Fresh to strong winds and seas to
6 ft are over the Gulf of Panama reaching as far as 03N. Light 
to gentle winds and seas of 4-5 ft are elsewhere.

For the forecast, fresh to strong NE winds will prevail in the
Papagayo region through Tue morning. Moderate NE winds will then
continue through Thu. Moderate to fresh N winds in the Gulf of
Panama will continue through Tue evening, increasing to locally
strong speeds tonight. Moderate N to NE winds will then continue
in the Gulf of Panama through Thu. Large NW swell from an 
ongoing Gulf of Tehuantepec gap wind event will continue to 
affect the Guatemala and El Salvador offshore waters through 
early this evening. 

REMAINDER OF THE AREA

High pressure is centered near 34N127W. A surface trough extends
from 17N132W to 11N133W. The pressure gradient between this area
of high pressure and the surface trough is supporting fresh to 
strong winds and seas in the 8 to 10 ft range in the vicinity of
the trough. Gentle to moderate winds and seas in the 5 to 7 ft 
range prevail elsewhere. 

For the forecast, the surface trough over the NW open waters is 
forecast to continue moving NW tonight. Fresh to locally strong 
winds will continue in the vicinity of the trough with seas to 10
ft. 

On Mon and Tue, strong high pressure building west of California
is expected to produce increasing N to NE winds and building 
seas north of 27N. The seas will be a product of both the N to NE
wind waves and large long-period NW swell.
