NWS National Hurricane Center Miami FL
1605 UTC Sat Apr 26 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 1200 UTC surface analysis and satellite imagery through
1430 UTC.

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

The monsoon trough extends from 10N75W to 07.5N79.5W to 08.5N89W
to 05.5N116W. The ITCZ continues from 05.5N116W to beyond
05N140W. Scattered moderate to strong convection is noted from
01.5N to 07.5N east of 88.5W, and from 03.5N to 08.5N between
90W and 137W.


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

Moderate to locally fresh N-NW winds prevail across the Baja
California waters becoming NW and extending southward to the
nearshore waters of Cabo Corrientes and Colima. Seas there are 4
to 6 ft in S swell. Light to gentle winds are over the remainder
of the open waters from Puerto Angel westward, where seas are
also 4 to 6 ft. Fresh to strong SW to W winds over the northern
Gulf of California overnight have begun to shift slightly
southward, with fresh northerly winds beginning to spill into the
extreme north waters. Seas there are 3 to 6 ft. Nocturnal
drainage flow is producing fresh northerly winds spilling into
the Gulf of Tehuantepec and extending to near 60 nm offshore.
Scattered thunderstorms continue offshore of Chiapas and are
shifting toward the SW and offshore of Tehuantepec and central
portions of Oaxaca.

For the forecast, a weak cold front will move into the Baja
Norte waters today and dissipate across the central Baja waters
Sun, with high pressure building modestly in its wake across the
area waters through Mon. Moderate NW winds across the Baja
waters will freshen late today through late Mon. Fresh to locally
strong SW to W winds will pulse again in the northern Gulf of
California tonight. N winds in the central Gulf of Tehuantepec
will pulse fresh to occasional strong at night through this
weekend.

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

Moderate to fresh easterly gap winds are across the Papagayo
region this morning, extending offshore to 88W. Moderate to
locally fresh northerly winds continue across the Gulf of
Panama southward to 06N. Light to gentle winds prevail
elsewhere. S-SW swell across the regional waters is producing
seas of 5 to 7 ft across the area waters, and 7 to 9 ft S of the
Galapagos Islands and eastward to Ecuador.

For the forecast, moderate to fresh E winds will pulse across
the Papagayo region each night and morning into next week as a
modest high pressure ridge continues N of the area across the
eastern Gulf of America. In the Gulf of Panama, moderate winds
will pulse nightly to fresh. Cross equatorial S-SW swell will
peak over the regional waters late today through Sun.

...REMAINDER OF THE AREA....

High pressure dominates the waters N of 10N and W of 110W,
centered on a 1029 mb high near 38N142W. The pressure gradient
between this area of high pressure and lower pressure in the
vicinity of the ITCZ is supporting fresh NE trade winds N of the
ITCZ to near 22N W of 130W and moderate to locally fresh NE
trades elsewhere S of 25N and W of 125W. Seas over these waters
are in the 6-9 ft range in merging S and N swell. A weak cold
front has moved into the northern waters overnight, and extends
from 30N122W to 28N140W. Fresh N to NW winds follow the front E
of 130W, with seas of 7 to 8 ft in new NW swell. Gentle to
moderate N to NE winds, and seas of 5-7 ft prevail elsewhere N of
the ITCZ and W of 110W. S of the ITCZ/monsoon trough, light to
gentle winds and seas of 6-8 ft in S-SW swell prevail. Scattered
thunderstorms continue within 120 nm of the ITCZ to the west of
105W.

For the forecast, locally fresh N to NW winds and rough seas
behind the cold front sweeping across the northern waters will
reach 120W by midday, then continue moving SE and will gradually
dissipate on Sun. Elsewhere, little change in winds and seas are
expected N of the ITCZ. Cross equatorial S swell will propagate
across the southern waters through the weekend, raising seas to
8-9 ft south of 10N between 100W and 120W through late today
before seas slowly subside through Sun.
