NWS National Hurricane Center Miami FL
1005 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 0600 UTC surface analysis and satellite imagery through
0830 UTC.

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

The monsoon trough extends from 08N78W to 07N83W to 11N93W to 
14N108W to 11N114W. The ITCZ extends from 05N130W to 03N140W. A 
surface trough is analyzed from 13N115W to 09N121W to 03N123W. 
Scattered moderate isolated strong convection is noted from 05N 
to 09N between 93W and 106W, and from 03N to 08N between 116W 
and 128W. Scattered moderate convection is noted from 11N to 14N
between 103W and 116W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A broad ridge associated with high pressure centered near 35N130W
is west of the Baja California peninsula. The gradient between 
the ridge and low pressures over Mexico is supporting moderate to
locally fresh winds near the Baja California peninsula. Gentle to
moderate winds prevail elsewhere over the 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 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 35N130W
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 13N115W
to 09N121W to 03N123W. 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.
