Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Wed Mar 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 1200 UTC surface analysis and satellite imagery through
1515 UTC.

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

A surface trough extends from the coast of Panama near 07N78W to
08N90W to 06N102W. The ITCZ stretches from 06N102W to 05N120W to
beyond 05N140W. Scattered moderate to isolated strong convection
is observed from the 00N to 08N and between the coasts of Panama
and Colombia and 105W. Similar convection is occurring from 
03N to 10N and between 109W and 137W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A 1029 mb high pressure system near 32N138W dominates the
tropical Pacific. Primarily fresh NNW-N winds are found across 
the offshore waters of Baja California. Large NW swell continues
to move across the regional waters and it is producing seas of 8
to 12 ft from Cabo San Lazaro northward, and 7 to 10 ft 
southward to offshore of Los Cabos. Gentle to moderate northerly 
winds are present in the Gulf of California from Tiburon island 
northward, while moderate to locally fresh N-NW winds are noted 
southward to the entrance of the gulf. Seas in the gulf are 2 to 
4 ft. Moderate to occasionally fresh NW-W winds are observed 
across the remainder of the Mexican offshore waters, including 
the Gulf of Tehuantepec. Seas in this region are 4 to 7 ft.

For the forecast, high pressure NW of the area will continue to 
build modestly across the regional waters through tonight.
Primarily moderate to fresh NNW winds will persist across the 
Baja offshore waters through early Fri, then diminish through the
weekend as high pressure dominates. Large NW swell associated 
with the dissipated cold front will continue to spread SE across
the offshore waters through tonight. Seas will begin to subside 
today and diminish to near 8 ft on Thu before a new surge of NW 
swell moves into the Baja Norte waters. 

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

Moderate Caribbean trade winds result in fresh easterly winds
across the Papagayo region to 90W, extending northward into the
Nicaragian offshore waters. Seas in this area are 4 to 6 ft.
Moderate to locally fresh N-NE winds are present in the Gulf of
Panama and south of the Peninsula de Azuero to 04N, with seas of
3 to 5 ft. Elsewhere N of 02N, moderate or weaker winds and seas
of 3 to 6 ft prevail. S of 02N, moderate S to SE winds and seas 
of 4 to 7 ft are prevalent.

For the forecast, winds across the Papagayo region are forecast
to remain moderate to locally fresh for the next few days. 
Moderate to occasionally fresh N to NE winds in the Gulf of 
Panama will continue through tonight, then become variable and 
less than 15 kt through Fri. Elsewhere, winds are forecast to be 
moderate or weaker the rest of this week. 

REMAINDER OF THE AREA

The aforementioned subtropical ridge dominates the tropical
Pacific, allowing for fairly tranquil weather conditions outside
of the deep tropics. The pressure gradient between the high
pressure and lower pressures in the deep tropics results in fresh
trades from 07N to 21N and W of 122W. NW-N swell is producing 8
to 11 ft seas in the area described. Moderate or weaker winds and
seas of 7 to 10 ft are found elsewhere in the basin.

For the forecast, large NW to N swell will continue to propagate
southward across the area, with the leading edge of 8 ft seas 
reaching 04N this afternoon. Seas across the waters N of 20N are
not expected to begin to diminish until Thu. The subtropical 
ridge will dominate most of the basin through the weekend, 
allowing for a large region of fresh trades W of 130W.
