Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Tue Apr 1 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 0600 UTC surface analysis and satellite imagery through
0830 UTC.

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

A surface trough extends westward from near the Panama-Colombia 
border to 09N90W, then westward to 03N108W. An ITCZ reaches 
southwestward from 03N108W across 00N123W to beyond 03N140W. 
Widely scattered moderate convection is noted near these
features from 00N to 08N between 84W and 135W.

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

A broad surface ridge extends southeastward from a 1028 mb high
near 35N138W to just south of the Revillagigedo Islands. This
feature is supporting moderate to fresh NW to N winds and seas at
6 to 8 ft in residual NW swell west of Baja California. Gentle to
locally moderate NW to N to ENE winds with 4 to 6 ft seas in mix
NW and SW swell dominate offshore waters of central and southern
Mexico. Gentle to moderate northerly winds with seas of 1 to 4 
ft prevail across the Gulf of California.

For the forecast, fresh to strong NW to N winds near the Baja 
California coast will persist and expand westward through Wed 
morning, then diminish to mainly moderate on Thu. Winds in the 
northern and central Gulf of California are expected to increase 
and reach fresh to strong this evening through Wed afternoon, 
which could peak at near-gale force at the northern Gulf late 
tonight into early Wed morning. A new set of NW swell producing 
rough to very rough seas will propagate southward through the 
Baja California offshore waters tonight through late Wed. Marine 
conditions are anticipated to improve afterward.

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

Convergent surface winds are triggering scattered showers and
isolated thunderstorms off the coast of Guatemala and El
Salvador. Moderate easterly winds are present at the Gulf of 
Papagayo, while moderate northerly winds are evident in the Gulf 
of Panama. Light to gentle winds prevail for the remainder of the
offshore waters. Seas across all offshore waters range from 3 to
6 ft in a mix of NW and SW swells. Refer to the ITCZ/Monsoon
Trough section for additional weather in the area.

For the forecast, gentle to moderate easterly winds in the Gulf 
of Papagayo will persist into the weekend. During the nights, 
these winds are going to peak at fresh through Thu night, and at 
strong Fri and Sat nights. Gentle to moderate with occasionally 
fresh northerly winds are expected at the Gulf of Panama through 
Wed night. A mix of NW and SW swells will keep moderate seas near
the Galapagos Islands and off Ecuador for the next several days.

...REMAINDER OF THE AREA....

A surface trough curves southwestward from 30N120W to 27N131W.
Patchy showers are seen up to 60 nm along either side of this
feature. Otherwise, a broad surface ridge extends southeastward 
from a 1028 mb high near 35N138W to just south of the 
Revillagigedo Islands. Gentle to moderate N to ENE to ESE winds 
and seas of 4 to 6 ft are evident north of 20N and west of 120W.
Tighter gradient between the ridge and the ITCZ is sustaining 
moderate to fresh NE to ENE trades and 6 to 9 ft seas in a mix of
long-period northerly and southerly swells from the ITCZ to 20N
and west of 120W. Gentle to locally moderate N to NE winds with 6
to 8 ft seas in NW swell are found north of the surface trough 
between 100W and 120W. Gentle to moderate ENE winds with 6 to 7
ft in mix of moderate northerly and southerly swells are present
south of the ITCZ and west of 110W. Light to gentle winds and
seas of 5 to 7 ft in a mix of moderate northerly and southerly
swells prevail for the rest of the waters west of 100W/120W. 
Seas.
 
For the forecast, northerly winds north of 20N between 118W and
126W will briefly increase and become fresh to locally strong 
tonight and Wed. Seas north of 20N and west of 120W will also
build tonight and reach 7 to 11 ft on Wed, then gradually subside
Thu and Fri. Little change is expected elsewhere through Sat 
over the open Pacific waters.
