Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Wed Apr 17 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 1800 UTC surface analysis and satellite imagery through
2000 UTC.

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

A trough extends from the Panama Colombia border near 07N78W to 
06N93W. The ITCZ continues from 06N94W to 05N115W to 07N138W. 
Scattered moderate convection is noted from 04N to 09N between 
133W and 138W. 

...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. Gentle to moderate winds and seas persist 
elsewhere.

For the forecast, NW swell of 7 ft off Baja California to the 
Revillagigedo Islands will gradually subside through late today. 
Gentle to moderate winds and moderate seas will persist elsewhere
through Sat. Looking ahead, fresh NW winds and building swell 
will follow a trough into the waters near Guadalupe Island off 
Baja California Norte by Sun. 

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

Moderate N gap winds have developed in the Gulf of Panama, with
seas of 5 to 7 ft. Gap winds have diminished in the Gulf of
Papagayo. Light to gentle winds and moderate seas of 3 to 6 ft 
in SW swell are noted elsewhere.

For the forecast, gap winds pulsing across Gulf of Panama will
diminish tonight. Gentle to moderate breezes will persist 
elsewhere through Sun, with mostly 4 to 6 ft combined seas 
primarily in SW swell.

...REMAINDER OF THE AREA...

Fresh trades are ongoing from 08N to 18N between 125W and 135W. 
These winds are active between a 1008 mb low pressure area along 
the ITCZ near 136W, and broad high pressure north of 20N. 
Combined seas are 8 to 11 ft in this area, in a mix of NW swell, 
S swell, and shorter-period easterly waves resulting from the 
trade wind flow. A broader area of mixed swell extends farther 
east of this area to about 115W. Gentle to moderate breezes and 
moderate seas are evident elsewhere.

For the forecast, wave heights will subside across the region
through Fri, 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 Sun.
