NWS National Hurricane Center Miami FL
0405 UTC Thu Apr 29 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 0000 UTC surface analysis and satellite imagery through
0240 UTC.

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

The monsoon trough extends from 09N84W to 09N114W to 07N122W. 
The ITCZ continues from 07N122W to 05N140W. Scattered moderate 
and isolated strong convection is noted from 03N to 10N between 
83W and 95W to 130W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Moderate to fresh winds prevail off the Baja California 
peninsula as well as over much of the Gulf of California. Gentle
to moderate winds prevail elsewhere over the open waters off 
Mexico. Seas are in the 4-6 ft range in a mix of northwest and 
south swell over the open waters off Mexico.

For the forecast, high pressure west of the region will support 
moderate to fresh winds off Baja California, locally strong in
the central and southern Gulf of California through the end of
the week. A set of northwest swell will build west of Baja
California late in the upcoming weekend into early next week. 
Farther south, seas will build through tonight as a set of 
southerly swell propagates across the area. Additional southerly
swell will further build seas slightly late Fri and Sat over the
waters south of the Gulf of Tehuantepec region, then subsiding 
Sun. 

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

Moderate winds are noted in the Papagayo region. Light to gentle
winds persist elsewhere. Seas are in the 4-6 ft range in 
lingering southerly swell, except 5-8 ft offshore of Ecuador.

For the forecast, gentle to moderate winds will persist across 
the region, with subsiding southerly swell.

REMAINDER OF THE AREA...

High pressure is centered north of the area near 34N129W with a 
ridge axis extending SE to near the Revillagigedo Islands. The 
pressure gradient between the area of high pressure and lower 
pressure in the vicinity of the ITCZ is supporting mainly 
moderate winds north of the ITCZ, with seas in the 4-7 ft range. 
Light to gentle winds and seas in the 5-7 ft range prevail 
elsewhere.

High pressure will continue north of the area with these general
conditions prevailing into the upcoming weekend. A set of 
northwest swell with building seas will propagate south of 30N 
between 120W and 130W late in the weekend into early next week.
