Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Thu Apr 24 2025

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 0000 UTC surface analysis and satellite imagery through
0320 UTC.

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

The monsoon trough enters the Pacific along the coast of Panama 
near 07N78W and extends to 08N91W to 05N101W. The ITCZ continues
from 05N101W to 06N125W to beyond 03N140W. A second ITCZ extends
from 02S120W to beyond 06S140W. Scattered moderate convection is
occurring from 03N to 08N between 83W and 94W, from 03N to 07N 
between 107W and 140W, and from 02N to 09N between 118W and 138W.

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

The resultant pressure gradient between the subtropical ridge and
a surface trough along the Baja California Peninsula continues to
support moderate to fresh NW winds across the peninsula offshores
and the Jalisco adjacent waters. The trough is also supporting
moderate to fresh SW winds in the northern Gulf of California.
Seas over these waters are in the 5-6 ft range, except to 3 ft
along the Gulf. Otherwise, light to gentle winds prevail
elsewhere with seas to 6 ft in SW swell. 

For the forecast, fresh NW winds will pulse in the bays offshore
of Baja California and near Cabo San Lucas each night and 
morning into early next week. Pulsing fresh to locally strong SW
winds can also be expected in the northern Gulf of California
through Sat. Looking ahead, occasional fresh to strong N winds 
will develop in the Gulf of Tehuantepec this weekend. 

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

With a frontal boundary moving across the Carolinas offshores,
the pressure gradient over the western Caribbean has diminished,
thus resulting in only moderate to locally fresh E winds in the
Papagayo region where seas are up to 6 ft. Recent scatterometer
data show moderate to fresh NNE winds in the Gulf of Panama N of
07N where seas are also in the 4-6 ft range. Elsewhere, light to
gentle winds and moderate seas in SW swell prevail. 

For the forecast, fresh to strong E winds are expected tonight
into Thu morning in the Gulf of Papagayo, then moderate to fresh
NE to E winds will pulse through early next week. Moderate to
fresh NNE winds will also pulse in the Gulf of Panama, reaching
as far south as 04N. Seas will be moderate in both gulfs the
entire forecast period. Looking ahead, S to SW swell will move 
into the waters offshore of Ecuador this weekend, leading to 
7-8 ft seas near the Galapagos Islands. 

...REMAINDER OF THE AREA....

A 1027 mb high centered north of the area near 37N145W extends 
ridging through the eastern Pacific waters north of the ITCZ. 
This set up continue to force a fetch of moderate to fresh NE
winds from just N of the ITCZ to about 18N and W of 115W where
recent altimeter data depict 6-8 ft seas. Locally moderate or
weaker winds prevail elsewhere along with moderate seas.

For the forecast, moderate to fresh NE to E winds will occur 
across the tropical watersw W of 120W this weekend as a broad
surface ridge will prevail across the eastern Pacific subtropical
waters. Rough seas to 8-9 ft will occur in tandem with these 
winds. Fresh winds will expand farther north to 30N this weekend 
as a weakening cold front drifts southward through the northern 
waters. Elsewhere, SW swell will produce rough seas to 8 ft south
of the equator Thu night through Sat.
