Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

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

The monsoon trough extends from 08N85W to 09N105W. The ITCZ 
continues from 09N105W to 09N115W to 05N130W to 07N140W. 
Scattered moderate isolated strong convection is observed from 
07N to 10N between 100W and 105W. Scattered moderate convection
is observed from 07N to 09N between 115W and 120W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A weak ridge is 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.
