Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Mon Sep 2 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
0830 UTC.

...TROPICAL WAVES...

A tropical wave is along 95W north of 03N, moving westward at 
10-15 kt. Scattered moderate to isolated convection is active 
from 10N to 15N between 93W and 96W.

A tropical wave is near 128W from 04N to 20N, moving westward at
10-15 kt. Scattered moderate convection is noted from 12N to 15N
between 128W and 130W.

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

The monsoon trough extends from 11N86W to 14N100W to 1011 mb low
pressure near 12N128W to 09N140W. Aside from the convection
described in the Tropical Wave section, scattered moderate 
convection is active from 11N to 14N between 121W and 124W.
 
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface ridge north of 20N is maintaining moderate to fresh NW
winds off the central coast of Baja California, where seas are
likely 4 to 6 ft. The pattern is supporting gentle to moderate breezes
elsewhere off Baja California, and gentle breezes over the
remainder of Mexican offshore waters. Combined seas are 3 to 5 
ft elsewhere in open waters, except 1 to 3 ft over the Gulf of 
California.

For the forecast, a surface ridge will continue to dominate the
offshore forecast waters of Baja California through the middle
of the week, supporting pulses of moderate to fresh NW winds off
the coast of Baja California between Cabo San Lazaro and Punta
Eugenia, mostly moderate winds and seas elsewhere. Looking ahead,
expect fresh northerly gap winds across the Gulf of Tehuantepec
by Fri.

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

Scattered moderate convection prevails across portions of the
Pacific coast of Costa Rica. Light to gentle winds prevail 
across the area north of the monsoon trough with slight to 
moderate seas. South of the monsoon trough, moderate S to SW 
winds are ongoing with moderate seas to 7 ft, highest east of the
Galapagos Islands.

For the forecast, gentle to moderate winds and moderate seas 
will persist across the region into mid week.

...REMAINDER OF THE AREA...

A surface ridge dominates most of the waters north of 20N and 
west of 115W. A recent scatterometer satellite pass indicated
fresh trade winds from 10N to 20N west of 130W, between the 
ridge to the north and 1011 mb low pressure along the monsoon 
trough near 128W. A recent altimeter satellite pass indicated
combined seas of 7 to 9 ft in this area, with components of 
northerly and southerly swell. Gentle to moderate breezes and 5-7
ft seas prevail elsewhere.
 
For the forecast, the surface ridge will continue to build 
across most of the forecast waters north of 15N and west of 110W 
through the next few days. Elsewhere, southerly winds south of 
the monsoon trough to the Equator will remain moderate through 
the week, with seas of 5-7 ft primarily in southerly swell.
