Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 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 1800 UTC surface analysis and satellite imagery through
2000 UTC.

...TROPICAL WAVES...

The axis of a tropical wave is near 90W north of 05N, moving 
west at 5 to 10 kt. Nearby convection is described below in the 
ITCZ/Monsoon Trough section. 

The axis of a tropical wave is near 108W, 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 15N107W. Scattered 
moderate to isolated strong convection is from 11N to 18N 
between 102W to 110W.

The axis of a tropical wave is near 118W from 04N to 16N, moving
W at around 5 to 10 kt. Scattered moderate convection is noted 
from 07N to 14N between 113W and 123W.

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

The monsoon trough extends from 10N85W to 15N107W to 09N136W. 
Scattered moderate convection is noted from 06N to 12N, E of 
100W. 

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

Moderate to fresh winds are 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 5-7 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 fresh winds along with showers and
thunderstorms will progress W from offshore SW Mexico to near 
the Revillagigedo Islands through Wed night 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 locally fresh gap winds are over and downwind the 
Gulf of Papagayo, with light to gentle winds elsewhere north of 
the monsoon trough. Gentle to moderate winds are south of the 
monsoon trough. Seas are ranging generally from 5 to 7 ft.

For the forecast, southerly swell to 8 ft between the Galapagos
Islands and Ecuador will subside across the region through Wed. 
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 low pressure over the 
western United States is supporting moderate to 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
gradually decay into late week. Along and S of the monsoon 
trough, SW winds combined with this long-period southerly swell 
will combine to induce occasional seas of 8 to 10 ft. Northerly 
swell over the waters north of 28N, with seas greater than 8 ft, 
will continue through Wed.
