Tropical Weather Discussion

NWS National Hurricane Center Miami FL

1605 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 1200 UTC surface analysis and satellite imagery through

1530 UTC.



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



The monsoon trough enters the Pacific near 10N85W and extends to

05N114W. The ITCZ extends from 05N124W to beyond 03N140W. A

second ITCZ has been analyzed from 02S126W to beyond 03S140W.

Widely scattered moderate convection is occurring from 03N to 07N

between 87W and 100W, and from 03N to 09N between 105W and 140W.



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



Moderate NW winds and seas of 5 to 7 ft are occurring offshore 

of Baja California and southwestern Mexico as ridging extends 

over the Mexico offshore waters. Gentle to locally moderate winds

prevail through the Gulf of California and offshore of southern 

Mexico. Seas of 1 to 4 ft are noted in the Gulf of California. 



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 on Sat 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 to strong E winds and seas to 6 ft prevail in the Gulf of 

Papagayo as high pressure prevails over central Mexico and low

pressure dominates the south-central Caribbean. Moderate to 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, fresh to locally strong E winds will occur 

across the Gulf of Papagayo through late this morning. Pulsing 

moderate to fresh E winds are then expected in this region 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....



Moderate to fresh NE to E winds are occurring from 05N to 20N and

west of 115W, 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. 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 predominantly E swell will combine with N swell in 

this region, promoting locally rough seas. Elsewhere, 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.
