Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Tue Mar 22 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 1200 UTC surface analysis and satellite imagery through
1530 UTC.

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

A surface trough extends from 07N78W near the border of Panama
and Colombia to 03N106W. From there, the ITCZ extends to beyond
06N140W. Isolated moderate convection exists from 00N-05N east of
92W. Scattered moderate and isolated strong convection is noted
from 05N-08N west of 115W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A 1030 mb high at 36N131W extends a surface ridge to 16N107W. NW
moderate to fresh winds prevail west of the Baja California
peninsula to Cabo Corrientes. Elsewhere winds gentle or weaker
are occurring. Seas are 7-9 ft primarily in NW swell west of the
Baja California peninsula, 1-3 ft in the Gulf of California, 4-6
ft elsewhere.

For the forecast, deepening low pressure over the Great Basin 
will force fresh to strong NW winds over the Gulf of California 
from Wed night through Thu afternoon. A strong cold front 
reaching SW Gulf of Mexico should cause gale-force N gap winds 
over the Gulf of Tehuantepec beginning Thu. These N winds may 
remain at gale-force through Sat. Seas may reach 12 ft Thu night
and Fri morning in the Gulf of Tehuantepec. Large NW swell west 
of the Baja California peninsula will gradually diminish over the
next day or two.

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

Fresh E winds are occurring over the Papagayo region this
morning. Elsewhere, gentle SE to S winds prevail south of the 
surface trough along 07N with gentle to moderate E winds north 
of the trough. Seas are 4-7 ft.

For the forecast, moderate Caribbean trades are forcing fresh to
strong E winds in the Papagayo region through at least Sat 
night. Elsewhere, winds should remain moderate or weaker over the
Central American and equatorial offshore zones for the next 
several days. Large W to NW swell of up to 9 ft from a 
Tehuantepecer gap wind event should begin impacting the Guatemala
and El Salvador offshore zones beginning Thu night.

REMAINDER OF THE AREA

The pressure gradient between a 1030 mb high at 36N131W and low
pressure along the ITCZ is contributing toward generally moderate
to fresh NE trades mainly between 08N-20N west of 130W. Seas in
this area are 8-10 ft. Additionally, fresh N winds are occurring
north of 27N between 120W-125W. Seas here are also 8-10 ft. Elsewhere
winds are moderate or weaker with seas 5-7 ft.

For the forecast, a cold front approaches our waters from the
northwest, but goes stationary and weakens before reaching 30N140W.
However, the high north of the area does diminish, allowing the 
trades to decrease substantially down to moderate or gentle over
most of the High Seas. NW swell associated with the cold front 
will reach our NW corner tonight and cause 8-9 ft combined seas 
north of 10N west of 130W through Fri before diminishing.
