Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

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

The monsoon trough axis extends from near the border of Costa
Rica and Nicaragua at 11N87W to 09N117W. The ITCZ extends from
09N117W to 07N127W. Scattered moderate and isolated strong
convection is noted north of 05N east of 90W and from 07N-11N
between 102W-129W.

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

A ridge of high pressure extends from a 1019 mb high at 29N121W
east-southeastward to 13N97W. Winds are gentle to moderate over
forecast waters. Seas are 6-7 ft in NW swell over Pacific waters
to Manzanillo, 6-7 ft in SW swell from Manzanillo to the Mexico-
Guatemala border, and 1-3 ft in the Gulf of California.

For the forecast, weak ridging over the waters west of the Baja 
California peninsula will promote gentle to moderate winds over 
forecast waters from Puerto Angel westward for the next several 
days. Looking ahead, 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 night and possibly lasting through
Mon morning. 

...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, 
AND WITHIN 750 NM OF ECUADOR...

Winds are light to gentle across the forecast waters, except
gusty to near gale force near thunderstorms due to the monsoon
trough. Seas are 7-8 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. Moderate S swell impacting the 
equatorial Pacific zones will diminish later today.

...REMAINDER OF THE AREA....

A ridge of high pressure extends from a 1019 mb high at 29N121W
east-southeastward to 13N97W. 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. South of the equator east of 120W,
seas are 6-8 ft in S swell. Remainder of forecast waters, seas
are 5-7 ft in mixed swell.

For the forecast, a slightly strong ridge will produce a larger
area of fresh NE winds and seas 8-9 ft between 07N-21N west of 
128W over the weekend. Elsewhere, little change in winds or seas
are expected for the next several days.
