NWS National Hurricane Center Miami FL
2205 UTC Wed Apr 28 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 1800 UTC surface analysis and satellite imagery through
1910 UTC.

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

The monsoon trough extends from northern Colombia near 07N73W to
10N88W to 06N99W to 10N107W to 08N115W to 06N128W. The ITCZ
continues from 06N128W To 04N140W. Scattered moderate and
isolated strong convection is noted from 04N to 12N between 82W
and 95W, from 01N to 11N between 95W and 106W, from 03N to 07N
between 105W and 118W, from 11N to 14N between 101W and 114W, and
from 03N to 11N between 118W and 127W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Moderate to fresh winds prevail off the Baja California 
peninsula. 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 to fresh winds are noted in the Papagayo region and
south of the Azuero Peninsula. Gentle to moderate 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 with a ridge axis
from 32N128W to 16N103W. 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.
