NWS National Hurricane Center Miami FL
0405 UTC Wed Apr 7 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
0300 UTC.

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

A surface trough is from 08N78W to 06N94W. The ITCZ continues 
from 06N94W to 07N110W to 03N129W to 05N140W. Scattered moderate 
isolated strong convection is noted from 05N to 08N between 88W 
and 92W, and within 120 nm north of the ITCZ west of 133W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Scatterometer data shows fresh NW winds north of Punta Eugenia,
and gentle to moderate winds elsewhere. Seas are 5-7 ft west of
the Baja California peninsula, and 4 to 5 ft elsewhere. Little
change is expected the next couple of days across the forecast
area. Fresh NW winds will prevail west of Baja California Norte 
through Sat. NW swell will increase seas in the waters off Baja 
California Norte Fri and Sat. Light to gentle winds are expected
elsewhere through Sun.

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

Scatterometer data shows moderate to fresh winds downstream from
the Gulf of Papagayo region, and light to gentle winds elsewhere. ,
Seas are 5-6 ft near the Gulf of Papagayo, 4 to 5 ft elsewhere. 
Little change is expected the next couple of days across the 
forecast area. Gentle to moderate winds and 3 to 5 ft seas will 
prevail across most of the forecast area through Sun.

REMAINDER OF THE AREA...

A weak ridge prevails over the waters east of 130W. A surface 
trough extends from 30N132W to 23N140W. A weakening, stationary 
low pressure area centered near 31N142W is acting to amplify the 
weak pressure gradient that currently exists across the forecast 
waters. Little change is expected the next couple of days. A weak
pressure gradient will continue through Fri with mostly gentle 
to moderate trade winds expected. High pressure will start to 
build over the northern waters later this week, strengthening 
trade winds north of the ITCZ near 15N and west of 130W Fri and 
Sat. Northerly swell will enter the northern forecast waters east
of 125W on Fri. Seas over this area will build to around 10-11 
ft Sat night and Sun.
