Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Fri Apr 4 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 1800 UTC surface analysis and satellite imagery through
2100 UTC.

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

A surface trough extends westward from near the Panama-
Colombia across 06N110W to 02N127W. Scattered moderate 
convection is depicted up to 180 nm along either side of the
trough between .

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

A broad surface ridge extends southwestward from a 1028 mb high
near 35N130W to south of Cabo Corrientes. This feature is
sustaining gentle to moderate with locally fresh NW to N winds
and seas of 6 to 7 ft west of Baja California and near the
Revillagigedo Islands and Cabo Corrientes. Gentle E to SE winds
and seas of 3 to 5 ft are present off southern Mexico. Gentle to
moderate NW to N winds with 2 to 5 ft seas prevail in the Gulf of
California.

For the forecast, moderate to locally fresh NW to N winds with 
moderate seas will dominate west of Baja California through 
midweek next week. Fresh to strong northerly winds are expected 
in the central and southern Gulf of California Sat and Sun 
nights. In the long term, fresh to strong gap winds will begin at
Tehuantepec late Sun night, then possibly reaching near-gale to 
gale-force Mon morning through Tue night. Rough to very rough 
seas are possible under the strongest gap winds. In addition, 
long-period NW swell might cause rough seas off Baja California 
during the first half of next week. 

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

Moderate to fresh with locally strong NE to E winds with 4 to 6
ft seas are present in the Gulf of Papagayo as low pressure 
prevails over northwestern Colombia. Otherwise, mainly gentle 
winds and seas at 3 to 5 ft are noted over the remainder of the 
offshore waters.

For the forecast, moderate to fresh easterly winds in the Gulf 
of Papagayo will pulse to strong during tonight, Sun night and 
Tue night. Moderate to fresh easterly winds are also expected 
well west of the Papagayo region, in the far southwestern 
offshore waters of Guatemala and El Salvador during the above 
days. Elsewhere, a mix of SW and NW swells will maintain moderate
seas between Ecuador and the Galapagos Islands into next week. 
Otherwise, gentle to locally moderate winds are expected across 
the remainder of the waters into early next week. 

...REMAINDER OF THE AREA....

A broad surface ridge extends southwestward from a 1028 mb high
near 35N130W to south of Cabo Corrientes. Gentle to moderate N to
E to SE winds and seas of 4 to 7 ft are noted north of 20N and 
west of 120W. Farther south from the ITCZ to 20N and west of 110W,
the pressure gradient between the high pressure and the ITCZ is 
supporting moderate to fresh NE to E winds and 7 to 9 ft seas in
mixed NW and NE swell. Otherwise, gentle to moderate winds and 
seas of 4 to 7 ft prevail over the remainder of the waters. 

For the forecast, moderate to fresh trade winds and rough seas 
will occur into Sun, generally between 05N and 25N west of 110W,
as high pressure prevails in the eastern Pacific. A cold front 
drifting eastward over the northern waters this weekend will 
weaken the influence of the ridge, leading to moderate trade 
winds in the aforementioned region early next week. A long- 
period NW swell associated with the cold front is forecast to 
progress southeastward across the waters Sun into next week, 
producing rough seas in excess of 8 ft north of 25N and west of 
135W by Sat late night, and north of 15N and west of 130W 
through Mon morning. Rough seas to 12 ft will be possible north 
of 24N and west of 130W on Sun. Rough seas will continue to 
progress southeastward through early next week.
