Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Sat Apr 17 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
2030 UTC.

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

The monsoon trough extends from 08N81W to 06N90W to 07N108W. 
The ITCZ axis begins near 07N108W and continues along to 07N120W
to 05N140W. Numerous moderate to isolated strong convection is from
02N to 10N E of 100W. Scattered moderate convection is from 06N 
to 11N between 100W AND 121W, and from 02N to 07N between 125W 
and 137W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

The pressure gradient between surface high pressure anchored by a
1025 mb high near 31N130W and lower pressure along western 
Mexico and the Gulf of California continue to support moderate to
locally fresh NW winds across the Baja California offshore 
waters with seas in the 5 to 6 ft range. These conditions will 
prevail through Sun morning when NW winds will diminish to gentle
to moderate. Gentle to moderate NW winds will then continue through
the middle of the week with seas increasing to 8 ft N of Punta 
Eugenia by Thu. 

Light to gentle variable winds are forecast in the Gulf of
California through mid-week, except for moderate to locally fresh
NW winds N of 27N expected Sun morning through early Mon. Seas
will be in the 1 to 3 ft range. Winds are gentle to moderate 
over the remainder of the area with seas in the 5 to 6 ft range. 

A moderate gap wind event over the Gulf of Tehuantepec may occur
on Wed. Seas over the Gulf of Tehuantepec should remain 5 to 6 
ft through Tue night, then increase to 6 to 8 ft Wed. 

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

Light to gentle winds and 4 to 6 ft seas will prevail across the
forecast waters through mid-week. Enhanced long-period SW swell 
is forecast to enter the equatorial waters on Sun evening and 
reach the Central America offshores Mon, continuing to affect the
region through the middle of the week. Seas to 8 ft are forecast
over the Equatorial offshores during that period. Otherwise,
widespread heavy showers and thunderstorms are affecting the
Central America and Colombia offshores associated with the
monsoon trough. This precipitation activity is forecast to
continue through Sun evening.

REMAINDER OF THE AREA...

The pressure gradient between a 1025 mb high near 31N130W and 
lower pressures across the ITCZ supports moderate to fresh NE to
E winds between the ITCZ and 20N W of 125W with seas to 8 ft. 
Gentle to moderate NE to E trade winds with seas to 7 ft are
elsewhere between the ITCZ/monsoon trough to 20N between 110W and
125W. The high pressure will continue to build Sun through early
next week, supporting fresh to locally strong winds through Tue
mainly W of 130W. Seas are expected to build up to 10 ft,
enhanced by mixed SW and NW swell.
