Tropical Weather Discussion

NWS National Hurricane Center Miami FL

0405 UTC Sat May 3 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 0000 UTC surface analysis and satellite imagery through

0255 UTC.



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



The monsoon trough extends from Costa Rica near 09N83W to 07N105W

and to 05N134W. The ITCZ stretches from 05N134W to beyond 

04N140W. Scattered moderate convection is observed from 04N to 

10N and east of 113W.



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



An extensive 1030 mb high pressure system near 35N147W extends

southeastward to the Revillagigedo Islands, supporting moderate

to locally fresh NW-N winds in the offshore waters of Baja

California. Seas in these waters are 4-6 ft. Light to gentle

winds and slight to moderate seas are prevalent in the Gulf of

California.



In the remainder of the Mexican offshore waters, including the

Gulf of Tehuantepec, moderate or weaker winds and slight to

moderate seas prevail.



For the forecast, the moderate to locally fresh NW winds will 

continue across the Baja waters through Sat morning, ahead of the

approaching cold front. The cold front will move into the Baja

Norte waters Sat evening and reach the central Baja waters Sun,

accompanied by a significant increase in winds and seas across

the Baja offshore waters, and strong to near gale-force westerly

gap winds across the Gulf of California through Mon morning.

Large NW swell will follow the front, with combined seas in

excess of 8 ft reaching the waters off Punta Eugenia by early

Sun, Cabo San Lazaro Mon, and the Revillagigedo Islands by Tue. 

The highest seas may reach 16 ft off Guadalupe Island. Relatively

benign marine conditions will persist elsewhere off southern 

Mexico through early next week. 



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

AND WITHIN 750 NM OF ECUADOR...



Scattered showers and isolated thunderstorms persist along the

monsoon trough and across the nearshore and offshore waters from

Colombia to Nicaragua. Weak high pressure north of the area 

supports gentle to locally moderate winds and slight to moderate 

seas across the Gulfs of Papagayo and Panama. Mainly moderate 

southerly winds and seas of 4-6 ft primarily in SW swell are 

found south of 05N.



For the forecast, gentle to moderate breezes will persist across

the waters off Central America, Colombia and Ecuador through 

the middle of next week, with moderate SW swell.



...REMAINDER OF THE AREA....



A strong cold front extends from 30N135W to 28N140W. Moderate to

fresh NE winds and moderate seas are occurring behind the frontal

boundary. A broad subtropical ridge centered northwest of the

discussion waters supports moderate to locally fresh easterly

winds and seas of 6-8 ft north of the ITCZ and west of 110W.

Elsewhere, moderate or weaker winds and moderate seas prevail.



For the forecast, the aforementioned cold front will continue to

move across the waters north of 20N through late Sat, and reach from

central Baja California to 23N140W by Sun evening. Strong high 

pressure building behind the front will promote fresh to locally 

strong N to NE winds and building seas to 16 ft behind the front 

through the weekend, with strongest winds and highest seas 

occurring east of 130W.
