Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Sat Apr 20 2024

Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 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
1440 UTC.

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

A surface trough extends from 08N78W to 07N83W to 08N94W to
06N115W. The ITCZ continues from 06N115W to 06N125W. It resumes
from 05N134W to beyond 03N140W. Scattered moderate convection is
noted from 05N to 10N between 84W and 126W, and from 01N to 04N
between 134W and 140W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Moderate to locally fresh NW winds, and seas of 5-6 ft persist 
along the coast and offshore waters of Baja California, between 
weak high pressure west of the area and lower pressure over 
central Mexico. Gentle winds and seas of 5-6 ft persist 
elsewhere, except seas of 1-3 ft in the Gulf of California.

For the forecast, gentle to moderate winds winds and moderate 
seas will persist today. Fresh NW winds and building swell can be
expected for the waters near Guadalupe Island off Baja 
California Norte Sun and Mon as the pressure gradient between 
high pressure building in from the NW and lower pressure over 
Mexico increases. Looking ahead, fresh gap winds may develop in 
the Gulf of Tehuantepec on Mon. 

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

Light to gentle winds, and seas of 5-6 ft prevail across the 
discussion waters.

For the forecast, light to gentle breezes will persist across the
region into the middle of next week. Wave heights will be mostly
4 to 6 ft primarily in SW swell, building to 5 to 7 ft off
Ecuador Sun. Looking ahead, moderate to fresh gap winds may
develop in the Gulf of Papagayo by mid-week.

...REMAINDER OF THE AREA...

A 1021 mb high pressure area is centered near 27N133W. The
pressure gradient between the area of high pressure, lower 
pressure in the vicinity of the ITCZ, and a surface trough from
10N127W to 03N127W is supporting moderate to fresh winds from 07N
to 20N between 120W and 140W, where seas are in the 7-8 ft 
range. A frontal boundary is over the NW waters from 30N134W to 
25N140W. Moderate winds and seas of 5-6 ft are west of the 
frontal boundary. Light to gentle winds are in the vicinity of 
the high center, with gentle winds noted elsewhere. Aside from 
the area where fresh trades are, seas are in the 5-7 ft range. 

For the forecast, wind speeds and wave heights will remain 
similar into early next week, with an area of 8 ft seas 
persisting from 08N to 12N W of 130W due to fresh trade winds 
and lingering swell. The frontal trough will dissipate this 
weekend.
