Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Mon Apr 25 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
0300 UTC.

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

A surface trough extends from the coast of Costa Rica near 09N84W
to 09N96W to 07N119W. The ITCZ extends west of a trough along 
126W from 06N129W to beyond 05N140W. Scattered moderate 
convection is noted from 05N to 09N and E of 93W, from 04N to 13N
between 102W and 121W, and from 05N to 11N W of 124W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Surface ridging prevails over the offshore waters of Baja California.
The pressure gradient between the high pressure NW of the area 
and lower pressure over Mexico is supporting fresh NW to N winds
along Baja California. Light to gentle N winds prevail across 
Baja California Sur. Seas range 8-10 ft in long- period NW swell 
across the waters W and SW of the Baja California peninsula. 
Light and variable winds, with 5-8 ft seas in a mixed swell, are 
over the S Mexico offshore waters. Moderate to fresh NW winds 
prevail across the northern portion of the Gulf of California, 
while gentle to moderate NW winds prevail over the remainder of 
the area. Seas range between 3-4 ft over the northern Gulf and 
at the entrance of the Gulf, and 2-3 ft prevail elsewhere. 
Patches of haze are possible offshore from central and S Mexico 
due to nearby persistent agricultural fires.

For the forecast, the fresh NW to N winds over Baja California 
will diminish to mainly moderate speeds tonight. Winds will 
diminish further to gentle and moderate speeds by Mon morning with
little change through Thu. Strong to near-gale N winds are 
expected in the Gulf of Tehuantepec region late Tue night and 
continue through Thu morning. The long-period NW swell over the 
waters W of Baja California will mostly subside by Mon afternoon,
with swell prevailing NW of Punta Eugenia through Thu.

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

Gentle S to SW winds are noted over the waters between Ecuador 
and the Galapagos Islands, and offshore waters of Costa Rica and 
Panama. Seas of 4-6 ft due to a moderate S to SW swell are over 
the offshore waters. Patches of haze are possible offshore of 
Guatemala and El Salvador due to nearby persistent agricultural 
fires. Scattered thunderstorms are currently moving off the 
coast of Guatemala and El Salvador into the offshores. 

For the forecast, the long-period moderate S to SW swell will 
persist across the region through most of the week. Fresh 
easterly winds are possible near the Papagayo region and offshore
Nicaragua from Thu through the end of the week. 

REMAINDER OF THE AREA

A broad surface ridging extends from a 1028 high center located 
near 33N137W southeastward to 18N114W. The gradient between this
ridge and lower pressure in the vicinity of the ITCZ is 
supporting fresh NE winds from 09N to 25N and W of 125W. Long- 
period NW to N swell throughout this area is producing seas of 
8-10 ft. Seas of 5-8 ft seas are noted N of 25N between 128W- 
137W. Gentle to moderate winds along with seas of 5-7 ft seas due
to long-period S to SW swell are noted elsewhere.

For the forecast, the long-period NW to N swell will gradually 
decay through Tue, which will allow for seas to subside. The 
southerly swell should sustain 5-7 ft seas across the remainder 
of the basin through the forecast period.
