NWS National Hurricane Center Miami FL
1605 UTC Sat Apr 23 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
1500 UTC.

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

A surface trough extends from the Costa Rica coast at 09N84W
across 08N100W to 08N115W. Scattered moderate convection is seen
from 04N to 09N between the Panama/Costa Rica coast to 94W, and
from 04N to 13N between 101W and 115W. An ITCZ continues from 
08N100W through 06N125W to beyond 05N140W. Scattered moderate to
isolated strong convection is noted up to 90 nm from either side
of the ITCZ.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A ridge maintains control of the weather regime of the offshore 
forecast waters of Baja California. The pressure gradient between
the ridge and relatively lower pressures over Mexico is 
supporting moderate to fresh NW-N winds over the waters west of 
the Baja California peninsula. Light and variable winds are over 
the remainder of the offshore waters. Gentle to moderate winds 
are over the Gulf of California. NW swell over the waters off 
Baja California Norte is bringing seas to 12 ft north of 29N. 
Areas of haze are offshore the coast of Mexico south of Cabo 
Corrientes due to nearby persistent agricultural fires.

For the forecast, fresh to locally strong NW to N winds will 
continue over most of the offshore waters of Baja California
through tonight. Long-period NW swell over the waters west of 
Baja California Norte will bring seas greater than 8 ft to the 
Revillagigedo Islands by early this evening. Strong north winds 
are expected in the Gulf of Tehuantepec region Tue night through 
Wed night. 

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

Gentle to moderate SE to S winds prevail over the waters between
Ecuador and the Galapagos Islands, with light to gentle winds 
elsewhere. Seas are 5-7 ft in a S to SW swell, reaching 7 ft 
between Ecuador and the Galapagos Islands. Haze is possible over 
the offshore waters of Guatemala and El Salvador due to nearby 
persistent agricultural fires.

For the forecast, the long-period S to SW swell will continue 
across the region. A new set of southerly swell will build seas 
slightly over the Central American offshore through tonight. then 
subside a little beginning on Sun.

REMAINDER OF THE AREA

High pressure ridging, anchored by a strong high center of 1031 
N of the area near 34N136W, continues over the waters N of 20N. 
The pressure gradient between the area of high pressure and lower
pressure in the vicinity of the ITCZ is supporting mainly fresh 
NE trade winds N of the ITCZ to near 25N and west of about 121W.
Gentle to moderate winds remain elsewhere. NW swell is propagating
across the discussion waters, with seas greater than 8 ft 
covering the waters northwest of a line from 30N116W to 24N114W 
to 05N140W. Seas are peaking to 13 ft N of 27N between 121W- 
126W. Seas are 5-7 ft elsewhere.

For the forecast, the long-period NW swell will continue to 
propagate southeastward across the forecast waters through the
weekend. Seas greater than 8 ft will cover much of the forecast 
waters west of 105W by Sun night, then begin to decay on Mon.
