Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Tue Apr 29 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 09N83W to 06N102W. The ITCZ 
continues from 06N102W to beyond 03N140W. Scattered moderate and
isolated strong convection is noted from 03N to 10N east of 
102W, and from 04N to 10N between 110W and 140W.

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

Moderate to fresh winds prevail west of the Baja California
peninsula, with moderate winds extending southward to the
Revillagigedo Islands. Light to gentle winds prevail elsewhere
across the open waters off Mexico. Gentle to moderate winds are
noted in the Gulf of California. Seas are in the 7-8 ft range 
west of the Baja California peninsula, extending southward to 
near the Revillagigedo Islands. Seas of 6-7 ft are noted 
elsewhere over the open waters off Mexico. Over the Gulf of 
California, seas are 3 ft or less, except to 5 ft near the 
entrance of the Gulf. 

For the forecast, a ridge of high pressure across the Baja 
waters will weaken slightly across the region through the 
remainder of the week. Moderate to fresh NW winds across the Baja
waters will diminish slightly through the remainder of the week.
Light winds are expected across the Gulf of Tehuantepec though 
Fri.

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

Moderate to fresh winds are over the Gulf of Papagayo, extending
westward to near 88W. Elsewhere, light to gentle winds prevail. 
Seas are in the 5-7 ft range in subsiding S to SW swell.

For the forecast, moderate to fresh winds will pulse across the 
Papagayo region through early Fri before diminishing. Moderate 
northerly winds across the Gulf of Panama will diminish slightly 
through Thu, then become light and variable into the upcoming 
weekend. 

...REMAINDER OF THE AREA....

A broad ridge dominates the regional Pacific waters N of 10N 
and W of 110W, centered on a 1033 mb high near 37N135W. The 
pressure gradient between this ridge and lower pressure in the 
vicinity of the ITCZ is supporting fresh NE trade winds N of the
ITCZ to 20N and W of 125W. Seas over these waters are in the 7-9
ft range in merging S and NE swell. Moderate to fresh 
anticyclonic winds dominate the remainder of the waters N of the 
ITCZ and W of 110W, with seas of 6 to 8 ft. S of the ITCZ/monsoon
trough, light to gentle winds and seas of 6-7 ft in subsiding 
S-SW swell prevail.

For the forecast, the broad high pressure ridge currently 
dominating the region W of 110W will remain in place through 
early Wed, then begin to weaken and shift SE, ahead of an 
approaching frontal system. Little change in winds and wave 
heights are expected N of the ITCZ through early Wed, before a 
decreasing trend ensues from the middle to end of the week.
