Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Fri Apr 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
1430 UTC.

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

A surface trough extends from 09N83W to 09N98W to 07N119W. The
ITCZ continues from 07N119W to 02N140W. Scattered moderate
isolated strong convection is noted from 03N to 08N between 94W
and 120W. Scattered moderate convection is from 02N to 05N
between 125W and 132W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A ridge dominates the offshore forecast waters of Baja 
California. The pressure gradient between the ridge and 
relatively lower pressures over Mexico is supporting fresh to 
locally strong NW winds over the waters mainly N of Cabo San 
Lazaro. Seas associated to these winds are in the 5-7 ft range. 
Gentle to moderate NW-N winds remain elsewhere over the waters 
west of the Baja California peninsula. Light and variable winds
are over the remainder of the offshore waters. Fresh to locally
strong winds are over the northern Gulf of California, with light
to gentle winds over the remainder of the Gulf waters. NW swell
has propagated into the waters off Baja California Norte, with
seas building to near 9 ft NW of Guadalupe Island. 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 prevail 
across most of the offshore waters of Baja California tonight 
into Sat night. Long-period NW swell will reach the offshore 
waters of Baja California N of Punta Eugenia today, building seas
to 12 ft by this evening. This swell will propagate SE, with 
seas greater than 8 ft reaching the Revillagigedo Islands by Sat 
evening. Strong north winds are expected in the Gulf of 
Tehuantepec region late Tue. 

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

Gentle to moderate winds prevail over the waters south of 05N, 
with light to gentle winds north of 05N. Seas are 4-6 ft in S to 
SW swell. Haze is possible over the offshore waters of Guatemala 
and El Salvador due to nearby persistent agricultural fires.

For the forecast, long-period S to SW swell will continue to 
propagate across the region, with a new set of southerly swell 
reaching the waters between Ecuador and the Galapagos Islands 
today. This swell will raise seas slightly over the Central 
American offshore waters tonight and Sat, before subsiding Sat 
night and into early next week.

REMAINDER OF THE AREA

High pressure continues over the waters N of 20N, while a
dissipating cold front is over the northern waters extending 
from near 30N120W to 26N140W. The pressure gradient between the 
area of high pressure and lower pressure in the vicinity of the 
ITCZ is supporting moderate to fresh NE trade winds N of the ITCZ
to near 22N and west of 120W. Winds behind the front are NW to N
moderate to fresh east of 134W and N gentle to moderate west of 
134W. Gentle to moderate winds prevail elsewhere. NW swell is 
propagating across the NW waters, with seas greater than 8 ft
covering the waters northwest of a line from 30N118W to 08N140W,
peaking around 15 ft near 29N130W. Seas are 5-7 ft elsewhere.

For the forecast, the long-period NW swell will continue to 
propagate southeastward across the forecast waters. Seas greater 
than 8 ft will cover much of the forecast waters west of 105W by 
Sun night before starting to subside. The cold front will weaken 
as it reaches the NE waters by early this evening.
