Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Wed Mar 24 2021

Tropical Weather Discussion for the eastern Pacific Ocean from
the Equator to 32N, east of 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
1520 UTC.

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

A surface trough extends from 10N85W to 05N98W. The ITCZ 
continues from 05N98W to 03N130W. Widely scattered moderate 
convection is noted from 02N to 06.5N between 85W and 101W, and
from 03.5N to 10N between 114W and 128W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A broad ridge associated with strong high pressure near 42N142W 
dominates the offshore waters west of Baja California to Cabo
Corrientes, producing moderate to fresh NW winds, and fresh to 
locally strong winds near the coast of Cabo San Lucas. Seas of 8
to 12 ft in NW swell will prevail across the waters west of Baja
California today, subsiding to 6-7 ft by Thu night.

Strong westerly winds across the north and central part of the 
Gulf of California overnight have become N to NW and diminished
to moderate to locally fresh this morning, and are expected to
diminish further today and early tonight. A surface trough will 
approach the northern Gulf of California Thu afternoon, with 
strong W to SW winds ahead of the boundary Thu through Fri 
morning. Farther south, no gap wind events are expected in the 
Gulf of Tehuantepec through Sun.

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

Scatterometer data overnight showed mostly gentle to moderate 
winds in the forecast waters. Seas are estimated to be in the 3 
to 5 ft range. 

Fresh to strong winds are expected in the Gulf of Papagayo 
region Fri night through Sun night. Mainly light to gentle winds 
are expected elsewhere. Moderate long-period SW swell will 
prevail across the region the next several days. 

REMAINDER OF THE AREA...

1038 mb high pressure centered north of the forecast area near 
42N142W is supporting fresh to locally strong trade winds north 
of the ITCZ and west of around 115W. The extent of these winds 
will retract today as the high pressure shifts northward.

Long period northerly swell dominates most of the forecast 
waters west of 110W, while long period cross-equatorial SW swell
continues to propagate into the area east of 110W, reaching the 
coastal waters of Mexico, Central America, Colombia and Ecuador. 
Additional pulses of SW swell will continue across the region 
through the weekend.
