Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

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

The monsoon trough extends from 08N79W to 08N100W to 07N107W. 
The ITCZ AXIS begins near 07N108W and continues along 04N125W to
05N140W. Numerous moderate moderate to isolated strong convection
from 02N to 09N between 80W and 95W. Scattered moderate
convection from 03N to 11N between 95W and 120W, and from 03N to
08N between 126W and 136W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

The pressure gradient between surface high pressure anchored by a
1022 mb high near 30N129W 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 as indicated by latest altimeter
data. These conditions will prevail through Sun morning when NW
winds will diminish to gentle to moderate. Afterward, gentle to 
moderate NW winds are forecast 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...

A weak pressure gradient between a 1022 mb high near 30N129W and
lower pressures across the ITCZ/monsoon trough region supports 
gentle to moderate and locally fresh NE trade winds. Seas are 5 
to 7 ft across the region. High pressure building north of 30N 
Sun through Tue will produce fresh to strong trade winds and 7 to
9 ft seas west of 130W. An enhanced SW swell may enter the 
equatorial waters beginning on Sun evening, raising seas to 8 to
9 ft. At the same time enhanced NW swell may enter the northern 
waters west of the Baja California, boosting seas there to 8 to 9
ft.
