Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Thu Apr 3 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
0300 UTC.

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

A surface trough extends southwestward from near the Costa Rica-
Panama border at 09N83W to 00N115W. The ITCZ extends from 
02S120W to 02.5S120W to beyond 04S120W. Scattered moderate 
convection is seen from 00N to 04N between 80W and 100W.

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

A broad surface ridge extends southeastward from 1024 mb high
pressure centered near 30N135W to near the Revillagigedo 
Islands. This feature is supporting fresh to locally strong NW to
N winds west of Baja California as measured by earlier 
scatterometer satellite data, along with 8 to 11 ft seas. 
Moderate with locally fresh NW to N winds and seas of 5 to 7 ft 
in moderate NW swell are present near the Revillagigedo Islands. 
In the Gulf of California, fresh to strong w winds and seas at 4 
to 7 ft dominate the northern Gulf, while moderate to fresh with 
locally strong W to NW winds with 3 to 5 ft seas exist across 
portions of the north and central Gulf in plumes. Mostly gentle 
NW to N, to NE winds and seas of 4 to 5 ft are found off central 
and southern Mexico.

For the forecast, fresh to locally strong NW to N winds west of Baja
California will linger through tonight, then diminish to
moderate with locally fresh nearshore Thu and Thu night. In the
northern and central Gulf of California, moderate to fresh with
locally strong winds are anticipated through this evening, and
again on Thu night. A similar scenario is also forecast for the
central and southern Gulf of California Sat night and Sun night.
Large NW swell will maintain rough seas west of Baja California
until early Fri, then subside to mainly moderate, with another
set arriving by early next week. Looking ahead, a surge of fresh
to strong northerly gap winds may develop in the Gulf of
Tehuantepec Sun night, which could increase further to minimal
gale-force early next week.

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

Localized fresh to strong easterly winds and 5 to 7 ft seas are 
present at the immediate Gulf of Papagayo, while moderate 
northerly winds and seas at 3 to 5 ft are evident elsewhere off
Central America. Farther south, light to gentle winds along with
4 to 7 ft seas in a mixed of SW and NW swells prevail off
Colombia and Ecuador. Refer to the ITCZ/Monsoon Trough section 
for convection in the offshore areas.

For the forecast, localized fresh to strong winds will pulse at times
in the immediate Gulf of Papagayo through Sat night, mainly
during nighttime and early morning hours. A mix of SW and NW 
swells will keep moderate seas near the Galapagos Islands and off
Ecuador through Thu.

...REMAINDER OF THE AREA....

A large dome of high pressure with a ridge extends southeastward
from 1024 mb high pressure centered near 30N135W to near the 
Revillagigedo Islands. This pattern is supporting fresh trade
winds and 6 to 8 ft seas in a mix of swell south of 20N and west
of 125W. Moderate NE winds persist elsewhere west of 110W, with 5
to 7 ft seas, except for 8 to 10 ft seas in NW swell north of
20N and east of 120W. Gentle NE to E breezes and 5 to 7 ft seas
in mixed NW and SW swell are noted east of 110W. 

For the forecast, the ridge will be quasi-stationary while 
weakening slightly through this weekend. This should allow winds
to dimish slightly across the trade wind belt. The NW swell will
also steadily decay which allow seas to subside slightly. A new
set of large NW swell will reach 30N140W by Sat afternoon, with
seas up to around 14 ft near 30N140W by early Sun. Seas of 8 ft
or greater will cover the waters west of a line from Punta
Eugenia to 05N127W by Mon evening. Little change is expected 
elsewhere through Sun over the open Pacific waters.
