Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Thu Apr 24 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...

The monsoon trough enters the Pacific near 10N84W and extends to
08N102W. The ITCZ extends from 08N103W to 07N123W, and resumes 
from 06N126W to 04N140W. A second ITCZ has been analyzed from 
01S124W to beyond 03S140W. Scattered moderate convection is 
occurring from 02N to 08N between 82W and 93W. Widely scattered 
moderate convection is ongoing from 04N to 09N between 102W and 
125W. 

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

Ridging extends over the Mexico offshore zones. Recent 
scatterometer satellite data depict locally fresh NW winds 
occurring near Cabo San Lucas, with gentle to moderate winds 
occurring elsewhere offshore of Baja California and southern 
Mexico. Mainly gentle winds prevail through the Gulf of 
California. Seas of 1 to 3 ft are noted in the Gulf, with seas of
5 to 7 elsewhere.

For the forecast, periodic fresh NW winds will occur offshore of
Baja California Sur, including near Cabo San Lucas, each night 
and morning through Sat. Elsewhere, pulsing fresh SW winds can be
expected overnight into early Fri in the northern Gulf of 
California, with fresh to strong SW winds occurring nightly in 
this region through this weekend. Looking ahead, widespread 
moderate to fresh NW winds will develop this weekend and continue
into next week offshore of Baja California ahead of a cold front
moving southward along the California coast. NW swell will 
promote rough seas in this region this weekend into next week. 
Elsewhere, occasional fresh to strong N winds will develop in the
Gulf of Tehuantepec this weekend. 

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

Fresh E winds and seas to 6 ft are occurring in the Gulf of 
Papagayo as high pressure prevails over central Mexico and low 
pressure dominates the south-central Caribbean. Locally fresh N 
to NE winds extend through the Gulf of Panama to as far south and
west as 05N82W. Otherwise, light to gentle winds and moderate 
seas in SW swell are noted across the remainder of the regional 
waters.

For the forecast, moderate to fresh E winds will pulse in the 
Gulf of Papagayo each night and morning into next week. Farther 
east in the Gulf of Panama, winds will pulse to moderate to 
locally fresh speeds nightly into Sat, with generally moderate 
winds expected thereafter. Looking ahead, a long-period Southern 
Hemisphere swell will promote rough seas offshore of Ecuador Fri 
night into Sun, including near the Galapagos Islands. 

...REMAINDER OF THE AREA....

Recent scatterometer satellite data depict moderate to fresh NE 
to E winds from 05N to 18N and west of 120W, as a moderate 
pressure gradient prevails between high pressure to the north and
the ITCZ to the south. Seas in this area range from 8 to 9 ft in
mixed N and E swell, as observed on altimeter satellite data. 
Farther north, gentle to moderate winds are noted, with seas of 5
to 7 ft. South of the monsoon trough and ITCZ, gentle to 
moderate S to SE winds and seas of 6 to 7 ft in S swell prevail. 

For the forecast, moderate to fresh NE to E winds will occur 
across the tropical waters west of 120W this weekend as broad 
ridging extends over much of the eastern Pacific. Short-period 
wind waves in NE to E swell will combine with S swell in this 
region, promoting locally rough seas. Farther south, a long- 
period Southern Hemisphere swell will promote rough seas south of
the equator through Fri morning, and south of 05N through Sat 
morning before seas slowly subside by Sun. Looking ahead, locally
fresh N to NW winds and rough seas will develop Fri night north 
of 27N behind a cold front moving southward through the northern 
waters.
