Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Sun Apr 25 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
0840 UTC.

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

The monsoon trough extends from 08N85W to 07N105W. The ITCZ 
continues from 07N105W to 05N121W to 04N140W. Scattered moderate
isolated strong convection is observed from 06N to 14N between 
104W and 117W, and from 04N to 10N between 117W and 140W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A ridge of high pressure prevails west of the Baja California 
peninsula. The pressure gradient between this ridge and low 
pressure over Mexico is supporting gentle to moderate winds west
of the Baja California peninsula. Light to gentle winds prevail 
elsewhere. Seas are in the 5-6 ft range over the open waters off 
Mexico, and 1-3 ft over the Gulf of California. 

For the forecast, fresh to strong SW to W gap winds will pulse 
into the northern Gulf of California tonight, ahead of a trough 
moving through the region. High pressure will build west of the 
region in the wake of the trough, supporting fresh winds off Baja
California by mid week. Farther south, southerly swell impacting
the waters south of 20N will subside through late today. Another
set of southerly swell will arrive by mid week.

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

Gentle to moderate winds prevail over the Gulf of Papagayo as
well as the Gulf of Panama. Light to gentle winds persist 
elsewhere. Seas are in the 4-6 ft range. 

For the forecast, light to gentle winds will persist today, with
subsiding southerly swell. Fresh to strong gap winds will pulse 
mainly overnight across the Gulf of Papagayo Mon and Tue. 
Additional southerly swell will move into the region by mid week.

REMAINDER OF THE AREA...

The pressure gradient between a high pressure ridge over the
northern waters and lower pressure in the vicinity of the ITCZ 
supports a large area of moderate to locally fresh trade winds 
north of the ITCZ to 20N west of 125W. Seas are 6 to 8 ft across
this region. The ridging over the northern waters will weaken
slightly into Mon. This will allow the areal coverage of 
moderate to fresh trade winds to diminish into early next week.
