Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 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 0600 UTC surface analysis and satellite imagery through
0900 UTC.

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

A surface trough is from 08N78W to 06N94W. The ITCZ continues 
from 06N94W to 05N120W to 06N140W. Scattered moderate isolated 
strong convection is noted from 03N to 08N west of 126W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Scatterometer data shows an area of moderate to fresh NW winds 
north of Punta Eugenia, and light to gentle 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 the sea
heights west of Baja California Norte Fri and Sat. Light to 
gentle winds are expected to continue 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 of
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 significant change is expected the next several days 
across the region. 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 32N133W to 23N140W. A weak 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 few days. The low will drift westward 
through tonight, but a surface trough is expected to persist just
west of 140W through Sat. A weak pressure gradient will continue
through Sat with mostly gentle to moderate trade winds expected.
High pressure will build modestly over the northern waters later
this week, and slightly strengthen trade winds north of the ITCZ
near 15N and west of 130W. Northerly swell will sweep south of 
30N east of 125W by late Fri. Seas over this area will build to 
around 10-11 ft Sat night and Sun.
