NWS National Hurricane Center Miami FL
0405 UTC Mon Feb 26 2024

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
0315 UTC.

...SPECIAL FEATURES...

Significant Swell in NW waters: A broad 1007 mb low pressure 
system located near 27N132W is producing a large area of 12 to 17
ft seas north of 19N and west of 130W, along with fresh to strong
winds. The 12 ft seas will spread as far south as 18N and as far
east as 128W tonight. As the low weakens and moves NE, the winds
will diminish to fresh to strong speeds, and the seas will 
subside to 9 to 11 ft by Mon evening in that area.

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

The equatorial trough extends from 06N77W to 01N96W. The ITCZ 
stretches from 01N96W to 04N111W to 05N129W. A north-south 
oriented surface trough is analyzed along 130W, south of 16N. 
The ITCZ continues from 05N133W to 02N140W. Scattered moderate 
convection is observed from 02N to 08N and between 106W and 
128W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A 1018 mb high pressure system remains positioned to the west of
the Baja California peninsula and extends southeastward to the
Revillagigedo Islands. Fresh to strong northerly winds and seas 
of 6-8 ft are present in the Gulf of Tehuantepec. Elsewhere, the
weak pressure gradient result in light to gentle winds and 
slight to moderate seas in the rest of the Mexican offshore 
waters.

For the forecast, fresh to strong N winds and seas to 8 ft will 
continue across the Gulf of Tehuantepec through tonight. Elsewhere
over the Mexican offshore waters, winds should generally remain 
moderate or weaker through Mon. Winds in the northern Gulf of 
California are forecast to increase to fresh to strong Mon 
evening and persist through Tue. Increasing NW to N swell may 
impact the waters offshore Baja California Norte by early Wed.

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

Ridging north of the area continues to support fresh to strong 
easterly trade winds in the Gulf of Papagayo region and 
downstream to 90W. Seas in these waters are 5-7 ft but will be 
building to 7-9 ft in the next 6-12 hours. Fresh to locally 
strong northerly winds and seas of 4-6 ft are present in the Gulf
of Panama. Elsewhere, moderate or weaker winds and slight to 
moderate seas prevail.

For the forecast, the high pressure north of the area will 
sustain pulsing strong to near gale-force winds during the nights
and early mornings through at least midweek in the Gulf of 
Papagayo and downstream waters, with seas 8 to 9 ft through early
this week. Northerly winds in the Gulf of Panama will pulse to 
fresh to locally strong speeds at night through Tue night, then 
to fresh Wed night.

...REMAINDER OF THE AREA...

A broad 1007 mb low pressure system positioned near 27N132W is
producing fresh to strong winds north of 22N and west of 128W.
Seas in these waters are 12-17 ft, with the highest seas
occurring near 25N137W. Seas of 8-12 ft are found north of 17N
and west of 124W. The remainder of the basin is dominated by a 
1018 mb high pressure system centered west of Baja California. 
Moderate to locally fresh easterly winds and seas of 6-8 ft are 
found south of 17N. Elsewhere, moderate or weaker winds and 
moderate seas prevail.

For the forecast, the aforementioned low pressure system will 
gradually weaken tonight as it moves northeastward, moving north 
of the area by Mon morning. Fresh to strong winds will continue 
Mon and Tue north of 25N. The seas in the NW part of the area 
will mostly subside below 12 ft by Mon evening, but a large area 
of 8 to 11 ft seas will continue through Tue night west of 120N 
and north of 05N. The seas will gradually subside Wed into Thu. 
Fresh NE-E winds will spread downstream from the Gulfs of 
Tehuantepec and Papagayo, affecting the eastern waters through 
early this week. Seas of 8 to 9 ft will persist into Mon. Farther
west, winds will increase to fresh NE from the ITCZ to 17N and 
west of 130W early this week with seas to 11 ft in NW to N swell.
