Tropical Weather Discussion

NWS National Hurricane Center Miami FL

2205 UTC Tue Apr 22 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 1800 UTC surface analysis and satellite imagery through

2000 UTC.



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



The monsoon trough extends from the coast of Panama near 09N79W

and continues to 05N103W. The ITCZ extends from there to beyond 

03N140W. Scattered moderate and isolated strong convection is 

noted from 05N-10N between 121W-133W. Scattered moderate

convection is occurring from 03N-08N east of 88W.



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



A weak ridge of high pressure is present from 25N125W

southeastward to 13N98W. Winds are moderate or weaker across all

of the waters. Seas are 4-6 ft in mixed NW and SW swell over the

Pacific waters, and 1-2 ft over the Gulf of California.



For the forecast, the weak ridge of high pressure will dominate 

the Mexican offshore waters for the next few days, continuing the

quiescent wind and wave conditions. Looking ahead, a stronger 

pressure gradient will increase NW winds along the Baja 

California peninsula to fresh to locally strong beginning on Fri 

night through the weekend.



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

AND WITHIN 750 NM OF ECUADOR...



Scattered showers and isolated thunderstorms continue to affect 

the offshore waters of Panama, Costa Rica and Colombia. A strong

ridge over the W Atlantic and Caribbean is forcing fresh NE to E

winds over the Gulf of Papagayo region, reaching downwind to 

88W. Elsewhere, winds are moderate or weaker. Seas are 4-7 ft in

SW swell.



For the forecast, the NE to E gap winds are expected to pulse to

fresh with locally strong over the Gulf of Papagayo region 

through Thu morning. Otherwise, moderate or weaker winds will 

prevail over the Central American and equatorial Pacific offshore

zones through the weekend. Looking ahead, moderate S swell 

should impact the equatorial zones on Sat and Sun. 



...REMAINDER OF THE AREA....



A 1035 mb high pressure is located at 41N143W with a ridge 

extending southeastward from 25N125W to 13N98W. A modest 

pressure gradient between the ridge and lower pressure over the 

ITCZ is forcing moderate to fresh NE trades from 06N-16N west of

118W with seas to 8 ft in mixed swell. Elsewhere, winds are 

gentle or weaker with 5-7 ft in mixed N and SW swell. 



For the forecast, little change in winds is expected through the

end of the week. Looking ahead, a weak cold front should reach

our N border on Fri night and Sat, but only accompanied by 

moderate winds. After the passage of the cold front, the ridge

will shift southeastward, enhancing the area of fresh trades on

Sat and Sun. A moderate S swell is anticipated to reach our S 

border east of 120W beginning on Thu night and continuing until 

Sat night.
