NWS National Hurricane Center Miami FL
0405 UTC Fri Apr 30 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
0230 UTC.

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

The monsoon trough extends from 07N78W to 08N87W to 11N101W to 
10N111W. The ITCZ extends from 05N129W to 04N140W. A surface
trough is analyzed from 13N112W to 04N118W. Scattered moderate 
isolated strong convection is noted from 05N to 10N between 91W 
and 107W, from 10N to 13N between 106W and 112W, and from 03N to
09N between 116W and 126W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A broad ridge associated with high pressure centered near 34N129W 
is west of the Baja California peninsula. The gradient between 
the ridge and low pressures over Mexico is supporting moderate 
to locally fresh winds off the Baja California peninsula as well 
as in the central 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, moderate to fresh winds in the central Gulf of
California will diminish overnight. Moderate to fresh NW to N 
winds will prevail west of Baja California through Sat night, 
becoming fresh to occasionally strong on Sun. Large NW swell will
build west of Baja California Sun and Mon. 

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

Light to gentle winds prevail across the region. Seas are in the
6-7 ft range in lingering southerly swell.

For the forecast, light to gentle winds will continue across the
region through Sun night, with southerly winds increasing south 
of the monsoon trough axis early next week. Moderate southerly 
swell will gradually decay through Tue.

REMAINDER OF THE AREA...

A broad ridge associated with high pressure centered near 34N129W
dominates the forecast waters. The gradient between the high and
lower pressure in the vicinity of the ITCZ is supporting moderate
winds north of the ITCZ, and seas in the 5-7 ft range. An area of
deep convection is persisting near a surface trough from 13N112W
to 04N118W. Light to gentle winds and seas in the 5-6 ft range 
prevail elsewhere.

High pressure will continue north of the area through the  
weekend. Large northwest swell will propagate south of 30N 
between 120W and 130W Sun and Mon. Marine conditions will 
improve on Tue.
