Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Thu Apr 18 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
1500 UTC.

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

A trough extends from Panama near 08N78W to 09N85W to 06N95W. 
The ITCZ continues from 06N96W to 04N121W to 05N137W. Scattered 
moderate convection is noted from 05N to 07N between 93W and 96W 
and from 04N to 08N between 116W and 130W.

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

Moderate NW winds persist along the coast and offshore waters of
Baja California, between weak high pressure west of the area and
lower pressure over central Mexico. NW swell moving through the 
regional waters is producing seas of 5 to 7 ft to the 
Revillagigedo Islands while subsiding. Gentle winds and moderate seas
persist elsewhere.

For the forecast, gentle to moderate winds winds and moderate 
seas will persist through Sat. Looking ahead, fresh NW winds and 
building swell will follow a weak cold front into the waters near
Guadalupe Island off Baja California Norte late Sun and Mon.

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

Moderate N gap winds persist in the Gulf of Panama, with seas of
4 to 6 ft. Light to gentle winds and moderate seas of 3 to 5 ft
in SW swell are noted elsewhere.

For the forecast, gentle to moderate breezes will persist across
the region into early next week. Wave heights will be mostly 4 
to 6 ft primarily in SW swell, building to 5 to 7 ft off Ecuador 
by Sun.

...REMAINDER OF THE AREA...

Broad ridging persists north of 20N, supporting moderate to 
locally fresh trade winds across the tropical Pacific west of 
120W. Combined seas are 8 to 10 ft in this area, in a mix of NW 
swell, S swell, and shorter- period easterly waves resulting from
the trade wind flow. Gentle breezes and moderate seas are 
evident elsewhere. Trade wind convergence is supporting a few  
clusters of thunderstorms along the ITCZ.

For the forecast, wave heights will subside across the region
into the weekend, although an area of 8 ft seas will persist 
from 08N to 12N west of 130W due to fresh trade winds and 
lingering swell into early next week.
