Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Sat May 11 2024

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 0000 UTC surface analysis and satellite imagery through
0230 UTC.

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

The monsoon trough extends from 10N86W to 10N100W to 06.5N110W. 
The ITCZ continues from 06.5N110W to beyond 08N140W. Scattered 
moderate isolated strong convection is noted from 05N to 13N 
between 86W and 106W. 

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

Moderate to locally fresh winds prevail west of the Baja 
California peninsula and southward to near the Revillagigedo 
Islands. Gentle to moderate winds are over the southern Gulf of 
California, with light to gentle winds elsewhere over the Gulf.
Gentle winds are noted elsewhere. Seas are in the 6-7 ft range
west of the Baja California peninsula, reaching 8 ft SW of the
coast of Cabo San Lucas. Elsewhere over the open water off
Mexico, seas are in the 4-6 ft range. Over the Gulf of
California, seas of 3 ft or less prevail.  

For the forecast, gentle to moderate northwesterly winds will 
prevail off the Baja California waters through early next week, 
with small areas of fresh winds developing along the coast during
the late afternoon and evening hours through Sat. Northwest 
swell will maintain seas to 8 ft through early Sat before 
gradually subsiding to 6 ft or less through early next week. 
Gentle to locally moderate winds and moderate seas are expected 
elsewhere across the open offshore waters of Mexico through the 
middle of next week. 

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

Gentle to moderate winds prevail S of the monsoon trough with
light to gentle winds N of the monsoon trough. Seas are in the
6-7 ft range between Colombia and the Galapagos Islands, with
seas of 4-5 ft elsewhere. 

Santa Maria and Fuego Volcanoes in Guatemala have been emitting 
narrow streams of ash, which has traveled west and southwestward
to near the Pacific coast of southwestern Guatemala. This ash 
may move into the nearshore coastal waters across this area this 
evening and continue to disperse. 

For the forecast, gentle to moderate S to SW winds south of the
monsoon trough are expected through early next week. Southerly 
swell moving through the regional waters will build seas to 6 to
7 ft S of the Galapagos Islands through Sun. Elsewhere, light to
gentle winds will prevail with moderate seas of 6 ft or less.

...REMAINDER OF THE AREA...

A ridge extends from high pressure of 1028 mb near 45N136W 
southward into the tropical eastern Pacific waters. The pressure 
gradient between the area of high pressure and lower pressure in 
the vicinity of the ITCZ is supporting moderate trades N of the 
ITCZ to near 20N and W of 120W. Seas over this area are in the 
6-8 ft range in NW swell. Gentle to locally moderate winds are 
elsewhere N of the ITCZ and monsoon trough, with seas in the 5-7 
ft range. Gentle to moderate winds are found S of the ITCZ and 
monsoon trough, with seas of 5-7 ft in mixed SW and SE swell.

For the forecast, moderate trade winds, and seas of 6-7 ft, are 
expected in the trade wind zone N of the ITCZ to near 20N and W 
of 120W through Sun, before seas subside slightly through early 
next week.
