Tropical Weather Discussion

NWS National Hurricane Center Miami FL

1005 UTC Mon May 5 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 0600 UTC surface analysis and satellite imagery through

0850 UTC.



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



The monsoon trough extends from Costa Rica near 10N85W to 10N100W

to 07N121W. The ITCZ extends from 07N121W to beyond 05N140W. 

Scattered moderate convection is from 00N to 10N E of 91W, from 

05N to 12N between 98W and 114W, and from 04N to 10N between 

117W and 133W.



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



A surface trough, remnants of a cold front, extends across the

southern Gulf of California to Las Barrancas in Baja California 

Sur to 22N116W. Fresh to strong SW winds are ongoing over the 

northern Gulf of California with seas to 6 ft. Moderate to fresh 

NW winds and rough seas to 14 ft follow the trough off Baja 

California Norte, being the highest seas WNW of Guadalupe 

Island. Fresh to strong winds are funneling off Cabo San Lucas 

where seas are 8 ft. Relatively benign marine conditions persist

elsewhere over Mexican offshore waters.



For the forecast, the surface trough will continue to move

across the southern Gulf of California today and dissipate 

tonight. Fresh to strong westerly gap winds will persist across 

the northern Gulf of California through later this morning. Fresh

to strong winds and seas to 8 ft will continue off Cabo San 

Lucas through tonight. Large NW swell associated with the trough,

with combined seas in excess of 8 ft will reach the waters off 

Cabo San Lazaro today, the Revillagigedo Islands Tue and subside 

Wed evening. Light to gentle breezes, except moderate to fresh 

NW winds off Cabo Corrientes, will persist elsewhere off southern

Mexico through Fri night. 



...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, 

AND WITHIN 750 NM OF ECUADOR...



Weather remains unsettled across the waters east of 90W as 

showers and isolated thunderstorms associated with the monsoon 

trough also impact Costa Rica, Panama and Colombia. This shower 

activity is supporting moderate to fresh SW to W winds across 

these offshore waters while a weak pressure gradient elsewhere is

resulting in light to gentle winds. Seas of 5 to 6 ft primarily 

in SW swell are ongoing across the offshore waters between 

Ecuador and The Galapagos as well as the Central America offshore

waters.



For the forecast, gentle to locally moderate breezes will 

persist across the waters off Central America, Colombia and 

Ecuador, with primarily moderate SW swell through the middle of 

the week. Looking ahead, large SW swell is expected in Ecuadorian

waters Tue night through Thu. 



...REMAINDER OF THE AREA....



A surface trough, remnants of a cold front, extends across the

southern Gulf of California to Las Barrancas in Baja California 

Sur to 22N116W. Fresh to locally strong N to NW winds follow the

trough, which is also impacting the subtropical waters north of 

23N and E of 131W with rough seas in the 8 to 14 ft range. 

Farther south, the extension of the subtropical ridge to near 

17N, is supporting a broad area of moderate to fresh trade winds 

and 7 to 9 ft seas in the deep tropics west of 125W, with a 

component of NE swell. Moderate or weaker winds and moderate 

seas are noted elsewhere. 



For the forecast, the aforementioned trough will dissipate as it

moves southward off the coast of Baja California Sur. Strong 

high pressure building behind the trough will promote fresh to 

locally strong N to NE winds and building seas through Tue, with

the strongest winds and highest seas occurring east of 130W. 

Winds and seas will diminish Tue night into Wed.
