Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Sat Apr 24 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 08N78W to 08N110W. The ITCZ 
continues from 08N110W to 04.5N123W to 05N140W. Scattered 
moderate isolated strong convection is observed from 03N to 10N 
between 93W and 120W, and from 05N to 10N between 130W and 140W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A ridge extends west of the Baja California peninsula. The 
pressure gradient between this ridge and lower pressure over 
Mexico is supporting moderate to fresh winds west of the Baja 
California peninsula. Light to gentle winds prevail elsewhere. 
Seas are in the 5 to 7 ft range primarily in SW swell over the 
open waters, with seas in the 1-3 ft range over the Gulf of 
California.

For the forecast, the winds off Baja California will diminish 
today as high pressure west of the area weakens. Long period 
southerly swell will maintain seas of 5-7 ft over the open 
waters through tonight before subsiding. A trough will move 
across Baja California Mon and Tue, followed by moderate to fresh
NW winds. 

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

Moderate to fresh winds prevail over and downstream of the Gulf 
of Papagayo. Light to gentle winds persist elsewhere. Seas are in
the 6 to 7 ft range over and downstream of the Gulf of Papagayo,
and 5-6 ft elsewhere. 

For the forecast, fresh gap winds will pulse mainly overnight 
across the Gulf of Papagayo through Sun, then becoming fresh to 
strong early next week. Long period cross- equatorial southerly 
swell will subside through tonight. Another smaller 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 23N west of 120W. Seas are 6 to 8 ft across 
this region. The ridging over the northern waters will weaken,
with areal coverage of moderate to fresh winds diminishing
through the weekend into early next week.
