Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Wed Mar 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 1800 UTC surface analysis and satellite imagery through
2130 UTC.

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

A surface trough extends from a 1010 mb low centered near 06N78W
to 05N108W. The ITCZ continues from 05N108W to 04N138W. 
Scattered moderate to isolated strong convection is occurring 
south of 07N and east of 93W. 

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

Fresh to locally strong N winds and locally rough seas in N 
swell are ongoing in the Gulf of Tehuantepec as troughing 
prevails north of the region. Elsewhere, a surface trough extends
over northwestern Mexico through the Gulf of California, and a 
1025 mb high is centered near 25N126W. The pressure gradient 
between these features is supporting moderate NW winds as 
observed on recent scatterometer satellite data, and seas of 6 to
8 ft off the coast of Baja California. Locally moderate SW winds
are noted in the far northern Gulf of California, with gentle 
winds occurring elsewhere through the Gulf. Otherwise, gentle to 
locally moderate winds and seas of 4 to 6 ft prevail offshore of 
southwestern Mexico. 

For the forecast, pulsing fresh to locally strong winds in the 
Gulf of Tehuantepec will occur through Thu morning. Locally 
rough seas will accompany these winds. Elsewhere, moderate NW 
winds offshore of Baja California will strengthen to fresh to 
locally strong speeds tonight as a cold front approaches from the
northwest. The cold front is slated to move through the Baja 
California waters Fri morning, supporting widespread fresh to 
locally strong NW winds in the wake of the front. A long period 
NW swell will progress southeastward Fri morning through this 
weekend, producing rough seas in excess of 8 ft offshore of Baja 
by Fri afternoon, and offshore of southwestern Mexico through 
Sat. Peak seas of 12 to 14 ft will impact areas north of Cabo San
Lazaro Fri morning through Sat. Seas will subside from northwest
to southeast early next week.

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

Fresh to locally strong NE winds and locally rough seas in NE 
swell are occurring in the Gulf of Papagayo as low pressure 
prevails over northwestern Colombia and troughing persists north 
of the region. Pulsing moderate N winds are noted in the Gulf of
Panama. Otherwise, gentle to locally moderate winds and seas of 
3 to 6 ft in S swell are occurring through the rest of the 
waters offshore of Central and South America.

For the forecast, pulsing fresh to strong NE winds will occur in
the Gulf of Papagayo through this weekend, with the strongest 
winds occurring each evening through the early morning hours. 
Locally rough seas in NE swell will accompany these winds. 
Farther east, N winds will pulse to fresh speeds in the Gulf of 
Panama through this weekend. Otherwise, moderate seas in S to SW 
swell will prevail across the waters offshore of Central and 
South America through early next week. 

...REMAINDER OF THE AREA....

A cold front extends through the northwestern waters from 
30N131W to 25N140W, and moderate to fresh NW winds are occurring 
to the north of this front, as seen on recent scatterometer 
satellite data. Rough seas of 8 to 12 ft are occurring north of 
25N and west of 131W. Otherwise, a 1025 mb high centered near 
25N126W extends ridging through much of the eastern Pacific 
waters. Moderate to fresh NE winds are occurring along the 
periphery of the ridge, from north of the ITCZ to 20N, generally 
west of 115W. A residual NW swell is leading to seas of 8 to 9 ft
in this region. Otherwise, gentle to locally moderate trade 
winds and seas of 5 to 7 ft prevail over the remainder of the 
waters.

For the forecast, the aforementioned cold front will progress
southeastward through Thu, leading to moderate to fresh NE to NW
winds in the wake of the front. A long-period NW swell associated
with system will expand southeastward across the open waters 
through this weekend, supporting seas in excess of 8 ft north of 
22N and west of 125W through Thu morning, and north of 15N and 
west of 110W through Fri morning. Peak seas of 12 to 17 ft are 
expected north of 22N between 120W and 140W tonight through Sat 
morning. Elsewhere, fresh NE winds generated by gap winds in the 
Gulf of Papagayo will extend as far south and west as 08N94W Thu 
morning through Fri. Otherwise, a tightening pressure gradient 
between the cold front and ridging over the eastern Pacific will 
lead to fresh to strong trade winds and rough seas between 05N 
and 20N west of 115W, with the most widespread fresh winds 
occurring Fri into Sat. Looking ahead, a cold front is slated to 
move through the northwestern waters waters this weekend, leading
to fresh to strong NW winds in the wake of the front.
