Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 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 1800 UTC surface analysis and satellite imagery through
2030 UTC.

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

A surface trough extends from low pressure of 1008 mb that is 
over the far southwestern Caribbean near 10N81W to 07N101W to
1010 mb low near 08N122W. The ITCZ continues from that point to 
beyond 04N140W. Scattered moderate convection is noted from 04N- 
09N and E of 93W, from 06N-12N between 118W-129W, and along the 
ITCZ mainly W of 134W. 

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 relatively lower pressures over Mexico is supporting fresh NW
to N winds along with 8-10 ft seas in long-period NW 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. 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 
waters, 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 northern Baja 
California will diminish to mainly moderate speeds this evening, 
then diminish slightly to gentle and moderate speeds early on Mon
with little change through Thu night. Strong to near-gale N 
winds are expected in the Gulf of Tehuantepec region late Tue 
night and continue through early on Thu. The long-period NW 
swell over the waters W of Baja California will prevail through 
mid week.

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

Gentle to moderate 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.

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 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 32N139W southeastward to 24N120W to 16N108W. 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 130W. 
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 begin to
to gradually decay through early week allowing for seas to 
subside. The southerly swell should sustain 5-7 ft seas across 
the remainder of the basin through the forecast period.
