Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Sun Apr 24 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
1530 UTC.

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

A surface trough extends from low pressure of 1008 mb that is 
over the far southwestern Caribbean near 09N81W to 09N118W, 
where it transitions to the ITCZ and continues to 05N130W to  
beyond 04N140W. Scattered moderate convection is noted from
04N-08N and E of 92W, from 05N-13N between 110W-128W, and along
the ITCZ mainly W of 134W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

High remains present over the offshore waters of Baja California.
The pressure gradient between the high pressure and relatively 
lower pressures over Mexico is supporting fresh NW to N winds 
along with 8-10 ft seas in long-period NW to N swell across the 
waters W and SW of the Baja California peninsula. Light and 
variable winds, with 5-6 ft seas in a S to SW swell are over the 
S Mexico offshore waters. Gentle to moderate winds, with seas 3 
ft or less are in the Gulf of California, except for slightly 
higher seas of 3-4 ft in the southern section of the Gulf. 
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 offshore Baja 
California will diminish to mainly moderate speeds this
afternoon, then diminish slightly to gentle and moderate speeds 
early on Mon with little through Thu night. Strong to near-gale 
N winds are expected in the Gulf of Tehuantepec region late Tue 
night through late Wed night into early on Thu. The long-period 
NW swell over the waters SW and W of Baja California will begin 
to gradually today and into early next week allowing for seas to 
subside.

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

Gentle to occassionally moderate S to SW winds exist 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.

For the forecast, the long-period moderate S to SW swell will 
persist across the region through most of next week. Fresh 
easterly winds are possible near the Papagayo region and Offshore
Nicaragua during the middle and latter part of the week. 

REMAINDER OF THE AREA

A broad surface ridging extends from a 1029 high center located 
near 34N139W southeastward to 24N120W and to near 18N114W. The 
gradient between this ridge and lower pressure in the vicinity of
the ITCZ is supporting mainly fresh NE to E winds west of line 
from near the southern tip of Baja California to 09N120W and to 
04N140W. Long-period NW to N swell throughout this area is 
producing seas of 8-10 ft, except for 5-8 ft seas in the NW part 
of the area. Gentle to moderate winds along with seas of 5-7 ft 
seas due to long-period S to SW swell are elsewhere.

For the forecast, the long-period NW to N swell will begin to
to gradually decay through early this week allowing for seas to 
subside. The southerly swell should sustain 5-7 ft seas across 
the remainder of the basin through most of next week.
