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.
