Tropical Weather Discussion

NWS National Hurricane Center Miami FL

0405 UTC Sun Apr 27 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

0130 UTC.



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



The monsoon trough extends from 10N83W to 06N109W. The ITCZ

continues from 06N109W to 05N140W. Scattered moderate and

isolated strong convection is noted from 03N to 10N between 80W

and 140W. 



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



Moderate to fresh NW winds prevail W of the Baja California

peninsula, extending southward to near the Revillagigedo 

Islands. Light to gentle winds are elsewhere over the open waters

off Mexico. Gentle to locally moderate winds are over the Gulf 

of California. Seas are in the 6-7 ft range over the open waters 

off Mexico, and 1-3 ft over the Gulf of California.



For the forecast, a weak cold front in the Baja Norte waters 

will move SE and dissipate across the central Baja waters Sun. 

High pressure will build into the Baja waters in the wake of the 

front. This pattern will support moderate to fresh NW winds 

across the Baja waters through late Mon. Fresh to locally strong 

SW to W gap winds will pulse in the northern Gulf of California 

tonight. Winds across the Gulf of Tehuantepec will become N and 

pulse fresh to occasionally strong at night through early Mon.



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

AND WITHIN 750 NM OF ECUADOR...



Moderate gap winds are over the Gulf of Papagayo, with light to

gentle winds elsewhere. S-SW swell across the regional waters is

producing seas of 5 to 7 ft across the area waters, and 7 to 9 

ft from W of the Galapagos Islands eastward to Ecuador. 



For the forecast, moderate to fresh E winds will pulse across 

the Papagayo region each night and morning into the middle of 

next week. Moderate northerly winds across the Gulf of Panama 

will pulse to fresh nightly through early Mon then diminish 

slightly next week. Cross equatorial S-SW swell will peak over 

the regional waters through Sun.



...REMAINDER OF THE AREA....



High pressure dominates the waters N of 10N and W of 110W. The 

pressure gradient between this area of high pressure and lower 

pressure in the vicinity of the ITCZ is supporting moderate to 

fresh NE trade winds N of the ITCZ to near 20N W of 115W. Seas 

over these waters are in the 6-9 ft range in merging S and N 

swell. A weak cold front extends from Baja California Norte to 

25N131W. Moderate to fresh N to NW winds follow the front E of 

130W, with seas of 6 to 8 ft in NW swell. Gentle to moderate N to

NE winds, and seas of 5-7 ft prevail elsewhere N of the ITCZ and

W of 110W. S of the ITCZ/monsoon trough, light to gentle winds 

and seas of 7-9 ft in S-SW swell prevail. 



For the forecast, locally fresh N to NW winds and rough seas 

behind the cold front sweeping across the northern waters will

continue through tonight across the waters E of 130W, as the

front moves SE and gradually dissipates on Sun. High pressure 

will then dominate the region W of 110W through Tue, with little 

change in winds and seas expected N of the ITCZ. Cross equatorial

S swell propagating across the area waters south of 10N between 

100W and 120W will slowly subside through Sun. High pressure will

weaken across the region Tue night through Thu, leading to a 

loosening of the pressure gradient and a modest decrease in 

winds and seas.
