Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Mon Jan 31 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 07N77W to 05N84W to 05N97W. The 
ITCZ extends from 05N97W to 08N132W. Scattered moderate 
convection is noted from 10N to 20N between 125W and 135W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Gentle to moderate winds prevail across the discussion waters,
except the northern Gulf of California where light to gentle
winds prevail. Seas are in the 1-3 ft range over the Gulf of 
California and 4 to 6 ft elsewhere.

For the forecast, building high pressure west of California 
combined with low pressure developing over the SW United States 
will produce fresh to strong NW winds and building seas over the 
waters west of Baja California Norte Tue night and Wed. This will
also help for fresh to strong winds over the Gulf of California 
from the middle to end of the week. 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 5-7 ft range. Moderate to fresh winds and seas 
to 5 ft are over the Gulf of Panama. 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, with moderate winds the
remainder of the week. Moderate to fresh N winds in the Gulf of 
Panama will continue through Tue evening, with moderate winds 
then continuing through the remainder of the week. 

REMAINDER OF THE AREA

A surface trough extends from 30N133W to 22N137W. High pressure 
is centered north of the area near 43W137W. The pressure gradient
between this area of high pressure and the surface trough is 
supporting fresh to strong winds over the northern part of the 
trough, N of 28N. Moderate to fresh winds are elsewhere north of
20N and west of 130W. Seas over this area are in the 8-9 ft 
range. Elsewhere, gentle to moderate winds and seas in the 4-7 ft
range prevail. 

For the forecast, the area of high pressure will remain fairly 
stationary while further building over the next 24 hours. This 
will bring an increase in winds with building seas N of 20N by 
Tue. The area of high pressure will weaken slightly midweek 
while the high center drifts southward. This will shift the fresh
to strong winds southward to cover the waters between 10N and 
20N and W of 120W from the middle to end of the week.
