0405 UTC Mon Apr 11 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 0000 UTC surface analysis and satellite imagery through
0230 UTC.

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

A surface trough extends from 08N78W to 05N90W to 05N100W. The 
ITCZ continues from 05N100W to 08N115W. It resumes west of a
couple of perturbations from 05N131W TO 04N140W. Scattered 
strong isolated strong convection is noted from 02N to 08N east
of 95W, from 05N to 12N between 100W and 113W, and from 04N to
12N between 113W and 130W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Fresh SE to S winds prevail across the central and northern Gulf
of California, with locally strong winds in the northern Gulf. 
Moderate NW winds prevail west of Baja California Norte. Light 
to gentle winds prevail elsewhere across the open waters off 
Mexico. Seas are 3-5 ft across the Gulf of California, 8-12 ft 
west of Baja California Norte, 6-9 ft off Baja California Sur in
NW swell, and 4-7 ft elsewhere offshore Mexico.

For the forecast, fresh to strong S to SW winds will persist 
across the northern Gulf of California through Tue morning. 
Northerly swell will prevail west of the Baja California 
peninsula through Mon. A cold front will move into the northern 
portion of the area by early Tue morning. Fresh to strong NW 
winds are expected behind the front to the west of Baja 
California Norte, with fresh winds off Baja California Sur. A 
reinforcing set of northerly swell will enter the area behind the
front. This will maintain wave heights in excess of 8 ft west of
the Baja California peninsula through Wed night or early Thu. 

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

Fresh to strong NE winds are noted across the Gulf of Papagayo 
region. Moderate to fresh N to NE winds are over the Gulf of 
Panama. Light to gentle winds prevail elsewhere, except for 
gentle to moderate southerlies offshore of Ecuador. Seas are in 
the 4-6 ft range, except 6-8 ft over the Papagayo region.

For the forecast, fresh to strong winds will pulse in the 
Papagayo region through the week. Fresh winds will pulse in the 
Gulf of Panama through Mon night, gradually diminishing to gentle
through midweek. Gentle to moderate S winds will prevail between
Ecuador and the Galapagos Islands through the next few days. 
Mainly light to gentle winds are expected elsewhere. S to SW 
swell will increase seas Mon through early Tue to the south of 
the Galapagos Islands and well to the west of Ecuador. 

REMAINDER OF THE AREA

High pressure of 1034 mb is centered north of the area near 
37N143W. This area of high pressure is supporting a tight 
pressure gradient that is producing fresh to strong NE winds over
the northwest portion of the area north of 25N and west of 120W.
Seas in this area are in the 10-14 ft range. Moderate to locally
fresh trade winds are elsewhere north of the ITCZ and west of 
130W, with gentle to moderate winds prevailing elsewhere. Seas 
are in the 6-8 ft range. Southern Hemisphere swell is affecting 
the area south of 04N between 100W and 125W, with seas in the 8-9
ft range.

For the forecast, the area of fresh to strong winds over the
northwest part of the area will start to diminish early Mon. 
Swell generated from these winds will spread southward, with seas
greater than 8 ft covering much of the waters north of 10N and 
west of 115W by Mon night. A cold front will enter the northern 
waters by early Tue morning, then extend from 31N113W to 26N121W 
to 30N134W by midday Tue. The front will continue southward 
before dissipating Tue night. The front will bring a reinforcing 
northerly swell to the area east of 125W and north of 22N Tue 
through Wed. Southerly swell from the Southern Hemisphere will 
continue to affect areas south of 05N between the Galapagos 
Islands and 125W through the early part of next week.
