Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 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 0600 UTC surface analysis and satellite imagery through
0830 UTC.

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

A surface trough extends from 08N78W to 07N111W. The ITCZ is
from 07N111W to beyond 03N140W. Scattered moderate convection is
noted S of 07N and E of 95W, and from 05N to 10N between 104W
and 124W.

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

Moderate to fresh NW winds and moderate seas 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 moderate seas persist elsewhere.

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

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

Moderate S winds and seas to 6 ft prevail across the waters W of
Ecuador. Light to gentle winds and moderate seas in SW swell are
noted elsewhere.

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

...REMAINDER OF THE AREA...

Broad surface ridging persists N of 10N, supporting moderate to
fresh trade winds across the tropical Pacific W of 120W.
Combined seas are 7 to 8 ft in this area, in mainly shorter-
period easterly waves resulting from the trade wind flow. Light
to gentle breezes and moderate seas are evident elsewhere. A
frontal trough has entered the far NW waters, but is having no
impact on sensible weather.

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.
