Tropical Weather Discussion

NWS National Hurricane Center Miami FL

2205 UTC Thu May 8 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

2100 UTC.



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



The monsoon trough axis extends from the coast of Costa Rica at 

09N84W to 10N116W. The ITCZ extends from 10N116W to 10N129W. 

Scattered moderate and isolated strong convection is noted from

07N-12N between 113W-130W. Isolated moderate convection is

occurring from 07N-10N between 85W-107W.



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



A ridge of high pressure extends from a 1027 mb high at 39N130W 

southeastward to 14N98W. Winds are light to moderate over 

forecast waters. Seas are 5-7 ft in NW swell over Pacific waters 

southward to Manzanillo, 6-7 ft in SW swell from Manzanillo to 

the Mexico- Guatemala border, and 1-3 ft over the Gulf of 

California.



For the forecast, a late season N gap wind event should begin 

Fri night over the Gulf of Tehuantepec. Winds are expected to 

reach gale force beginning Sat afternoon and possibly last 

through Mon morning. Elsewhere, weak ridging over the waters west

of the Baja California peninsula will promote gentle to moderate

winds over forecast waters from Puerto Angel westward through 

the weekend. Looking ahead, on Mon and Tue stronger offshore 

ridging should enhance the NW winds west of the Baja California 

peninsula to fresh conditions. 



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

AND WITHIN 750 NM OF ECUADOR...



Winds are light to gentle across the forecast waters. Seas are 

6-7 ft in S swell over the equatorial zones, and 5-6 ft in SW 

swell over the Central American zones.



For the forecast, light to gentle winds across the forecast 

waters will persist into the weekend. Looking ahead, E gap winds 

over the Gulf of Papagayo region will increase to fresh to strong

speeds starting Sun night into early next week. 



...REMAINDER OF THE AREA....



A ridge of high pressure extends from a 1027 mb high at 39N130W 

southeastward to 14N98W. The weak pressure gradient between the 

ridge and lower pressure over the monsoon trough/ITCZ is forcing 

only moderate to fresh NE trades with seas 7-8 ft in mixed wind 

waves and N swell from 09N-15N west of 110W. Elsewhere, winds are

gentle to moderate and seas are 5-7 ft in mixed swell.



For the forecast, a slightly stronger ridge will produce a 

larger area of fresh NE winds and seas 8-9 ft between 07N-21N 

west of 128W on Sat and Sun. By early next week, a further

increase in the strength of the ridge may cause the NE trades to

be fresh to strong over an expanded area north of 10N and west 

of 115W.
