Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Fri Apr 9 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
0120 UTC.

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

A surface trough extends from 08N77W to 07N95W. The ITCZ 
continues from 07N95W to 03N140W. Scattered moderate to strong 
convection is noted from 05N to 08N between 86W and 94W, and from
03N to 11N between 83W and 86W. Scattered moderate isolated
strong convection is noted elsewhere N of 05N east of 83W, and 
from 05.5N to 07.5N between 101W and 124W. Scattered light to
moderate convection noted from 26N to 30N between 138W and 141W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A ridge of high pressure prevails west of the Baja California,
and extends southeast to well offshore of Cabo Corrientes. The 
pressure gradient between the ridge and a trough over Mexico is 
supporting fresh to locally strong northerly winds off Baja 
California Norte and moderate to locally fresh winds off Baja 
California Sur. Light to gentle winds prevail elsewhere. Seas are
in the 5-6 ft range west of Baja California, 3-5 ft over the 
remainder of the open waters off Mexico, and 1-3 ft over the Gulf
of California. 

Fresh to strong NW winds will prevail west of Baja California 
Norte through Sun. NW swell will increase seas off Baja 
California Norte Fri through Tue. Gentle to moderate winds are 
expected elsewhere through Tue. 

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

Light to gentle winds prevail across the forecast area. Seas are
in the 3-5 ft range. Little change in wind and wave conditions 
are expected through Tue. However, very active weather described
above is expected to continue across the offshore waters N of 04N
and east of 95W through Fri night.

REMAINDER OF THE AREA...

Deep layered low pressure west of the area is accompanied by a 
1015 mb surface low near 29N146W. A surface trough east of this 
feature extends along about 138W and north of 123W. Scattered light
to moderate convection is seen along and west of this trough from
26N to 30N and extends to 141W. High pressure prevails across 
the northern waters east of this trough. There is a modest  
pressure gradient over the forecast waters. Moderate to locally 
fresh winds prevail north of the ITCZ to near 15N and west of 
115W. Seas over this area are in the 6-8 ft range. Gentle to 
moderate winds and seas in the 4-5 ft range prevail north of 20N.
Light to gentle winds and seas of 4-6 ft prevail elsewhere. 
Little significant change is expected the next couple of days. A 
weak pressure gradient will continue through Sat with gentle to 
moderate trade winds expected. High pressure will build modestly 
over the northern waters Sat through Mon, and slightly strengthen
trade winds north of the ITCZ. Northerly swell will propagate 
south of 30N east of 125W by late Fri. Seas over this area will 
build to around 10-11 ft Sat night and Sun.
