Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 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 0600 UTC surface analysis and satellite imagery through
0900 UTC.

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

A surface trough extends from the coast of Costa Rica near 09N84W
to 09N100W to 07N120W. The ITCZ extends west of a trough along 
126W from 06N129W to beyond 04N140W. Scattered moderate 
convection is noted from 05N to 12N and E of 95W, from 07N to 
12N between 99W and 114W, and from 04N to 11N and W of 120W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Surface ridging continues to prevail west of the Baja 
California peninsula. The pressure gradient between the high 
pressure NW of the area and lower pressure over Mexico is 
supporting moderate to fresh NW to N winds off Baja California. Light
to gentle N winds prevail across Baja California Sur. Seas range
8-9 ft in long- period NW swell across the western offshore waters
of Baja California. Light to gentle winds and seas of 5-8 ft 
in mixed swell are noted across the S Mexico offshore waters. 
Moderate to fresh NW winds prevail across the northern Gulf of 
California and gentle to moderate NW winds prevail over the 
remainder of the Gulf. Seas range between 3-4 ft over the 
northern portions 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, gentle to moderate northerly winds will prevail
across the Baja California offshores through Thu, increasing to
fresh by the end of the week. 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 this
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

Light to gentle S to SW winds prevail across the area. Seas of 
3-5 ft are noted across the Central American offshores with 4-6
ft across the South American offshores. These seas are within a
moderate S to SW swell. Patches of haze are possible offshore of
Guatemala and El Salvador due to nearby persistent agricultural 
fires. Scattered thunderstorms are noted off the coast of
Nicaragua, Costa Rica, and Panama. Isolated thunderstorms are
also noted off the coast of Colombia.  

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 Wed through the end of the week. 

REMAINDER OF THE AREA

A broad surface ridging extends from a 1029 high center located 
near 33N140W southeastward to 17N115W. The gradient between this
ridge and lower pressure in the vicinity of the ITCZ is 
supporting fresh NE winds from 09N to 28N and W of 115W. 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 and W of 119W. 
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.
