Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Tue Jul 23 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

...TROPICAL WAVES...

The axis of a tropical wave is near 89W north of 05N, moving 
west around 10 kt. Nearby convection is described below in the 
ITCZ/Monsoon Trough section. 

The axis of a tropical is near 106W, between 05N and 15N, moving
W at 5 to 10 kt. Weak low pressure is noted where this wave is 
intersecting the monsoon trough, near 13N106W. Scattered moderate
convection has developed from 11N to 18N between 102W to 109W. 

The axis of a tropical wave is near 116W from 04N to 16N, moving
W at around 5 kt. Weak low pressure is noted where this wave is 
intersecting the monsoon trough, near 12N116W. Scattered moderate
convection is noted from 09N to 14N between 111W and 119W.

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

The monsoon trough extends from 10N85W to 13N106W to 12N116W to
09N140W. Scattered moderate convection is noted from 06N to 12N,
E of 100W and from 06N to 11N between 120W and 125W. 

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

Moderate to locally fresh winds are also noted off SW Mexico due
to a passing tropical wave and associated low pressure center. 
Light to gentle winds prevail elsewhere. Seas are in the 6-7 ft 
range west of the Baja California peninsula and 4-6 ft elsewhere 
over the open waters off Mexico. Seas of 1-3 ft are noted over 
the Gulf of California. 

For the forecast, moderate to locally fresh winds along with
showers and thunderstorms will progress W from offshore southern
Mexico to near the Revillagigedo Islands through mid-week in
association with a tropical wave and weak low pressure. Elsewhere,
gentle to moderate breezes and slight to moderate seas will 
persist. 

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

Moderate to fresh gap winds are over and downwind the Gulf of 
Papagayo, with light to gentle winds elsewhere north of the 
monsoon trough. Mainly moderate winds are south of the monsoon 
trough. Seas are in the 5-7 ft range, except 7-8 ft between the 
Galapagos Islands and Ecuador. 

For the forecast, southerly swell to 8 ft between the Galapagos
Islands and Ecuador will subside across the region through mid 
week. Elsewhere, gentle to moderate winds and moderate seas 
will persist.

...REMAINDER OF THE AREA...

A ridge extends from a 1035 mb high pressure center near 41N147W
across the discussion waters N of 20N. The pressure gradient 
between this area of high pressure and deep low pressure over the
western United States is supporting fresh winds over the 
discussion waters N of 25N and W of 125W, along with seas of 8 to
10 ft. Elsewhere N of the monsoon trough, gentle to moderate 
winds and seas of 5 to 7 ft prevail. South of the monsoon 
trough, moderate to locally fresh winds and seas of 5-8 ft in 
southerly swell dominate.

For the forecast, seas to 8 ft in S long- period swell will 
linger around the equator through most of the week. Along and S
of the monsoon trough, SW winds combined with this long-period
southerly swell will combine to induce occasional seas to 8 ft. 
Northerly swell over the waters north of 28N, with seas greater 
than 8 ft, will continue through at least the middle of the week.
