Tropical Weather Discussion

NWS National Hurricane Center Miami FL

1005 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 0600 UTC surface analysis and satellite imagery through

0730 UTC.



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



The monsoon trough extends from 08N78W to 06N110W. The ITCZ 

continues from 06N110W to 04N140W. Scattered moderate and 

isolated strong convection is noted from 04N to 10N between 82W 

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. Fresh to locally strong winds are over the northern 

Gulf of California, with gentle to moderate winds elsewhere in

the Gulf. Seas are in the 6-7 ft range over the open waters off 

Mexico, 4-5 ft over the northern Gulf of California, and 1-3 ft 

over the remainder of the Gulf.



For the forecast, high pressure will build into the Baja waters, 

supporting moderate to fresh NW winds across the Baja waters 

through late Mon. 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 to fresh 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 6-7 ft across the area waters, and

7-8 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 today.



...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 21N W of 118W. 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. Gentle to moderate winds, and seas of 5-8 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, high pressure will 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 gradually 

subside today. 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.
