Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 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 0600 UTC surface analysis and satellite imagery through
0820 UTC.

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

A surface trough extends from low pressure 1009 mb near 08N77W 
to 06N80W to 08N87W to 08N90W to 06.5N102W. The ITCZ extends 
from 06N105W to 04N131W to beyond 05N140W. Scattered moderate to
strong convection is noted from the 00N to 07.5N between 79W and
105W. Scattered moderate isolated strong convection is found 
from 02.5N to 09.5N and between 108W and 128W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

The remnants of the frontal boundary that has moved through the 
area in the past 24 hours can be seen in satellite imagery 
extending from offshore of Baja California Sur near 20N112W to 
beyond 18N120W. 0400 to 0500 UTC satellite derived winds showed 
fresh NNW to N winds across the offshore waters of Baja, with 
small areas of strong winds across a few sections of the
coastline, and a broader area of strong N winds offshore of Los
Cabos. Large NW swell continues to move across the regional 
waters and 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 prevail across central and 
south portions of the Gulf of California. Seas inside the Gulf 
are generally 2-4 ft. Gentle to moderate NW to W winds prevail 
across most of the remaining offshore waters from Cabo Corrientes
to Puerto Angel, then become S to SW across Tehuantepec, with 
highest winds along the coast. Seas there are 4 to 5 ft. 

High pressure NW of the area will continue to build modestly 
across the regional waters tonight through late Wed as the 
frontal remnants shift further SSE and dissipate. Large NW swell 
associated with the cold front have peaked tonight across the
waters north of Los Cabos, and will continue to spread SE across
the offshore waters through late Wed. Seas will begin to subside
Wed and fade to 7 to 8 ft on Thu before new surge of NW swell
moves into the Baja Norte waters. 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.

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

Satellite derived winds from 0330 UTC showed fresh easterly  
winds across the Papagayo region, and extend offshore to 88W and
northward across the NW Nicaragua waters. Seas are 4-6 ft in the
region. Moderate N to NE winds are found across much of the Gulf
of Panama, with seas of 3-5 ft. Elsewhere N of 02N, moderate or 
weaker winds and seas of 3-5 ft prevail. S of 02N, moderate to 
locally fresh S to SE winds and seas of 4-7 ft are present.

Winds across the Papagayo region are expected to pulse to 
between fresh and locally strong late tonight through Wed 
morning, then remain moderate to locally fresh for the next few 
days. Moderate to fresh N to NE winds in the Gulf of Panama will 
continue through tonight, then become variable 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 ill defined remnants of the cold front extend from near 18N120W
W-SW to near 130W. No significant convection is seen near the
frontal remnants. Recent satellite-derived wind data showed
moderate to fresh N to NE winds from 06N to 28N between 120W and
130W. The NW to N swell behind the old front is resulting in 8 
to 11 ft seas. The rest of the basin is dominated by a building 
high pressure ridge anchored on a 1031 mb high near 32N138W. The 
pressure gradient between the subtropical ridge and lower 
pressures in the deep tropics is allowing for NE to E fresh 
trades W of 130W to the S of 27N. Elsewhere, moderate or weaker 
winds prevail.

Large NW to N swell will continue to propagate southward across 
the area, with the leading edge of 8 ft seas reaching 06N Wed 
morning. 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.
