NWS National Hurricane Center Miami FL
0405 UTC Mon Jul 22 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
0200 UTC.

...TROPICAL WAVES...

The axis of a tropical wave is near 81W north of 05N, moving 
west at 10 to 15 kt. Nearby convection is described below in the
ITCZ/Monsoon Trough section. 

The axis of a tropical wave is near 100W north of 05N, moving W 
of 10 to 15 kt. Nearby convection is described below in the 
ITCZ/Monsoon Trough section.

The axis of a tropical wave is near 113W from 04N to 16N, moving
west at 10 to 15 kt. Nearby convection is described below in the
ITCZ/Monsoon Trough section. 

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

The monsoon trough extends from 10N85W to 11N105W to 10N140W. 
Scattered moderate convection is noted from 04N to 10N E of 91W,
from 06N to 13N between 98W and 120W, and from 05N to 10N 
between 120W and 140W.

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

Gentle to moderate winds are west of Baja California Norte.
Moderate winds are off SW Mexico in association with a tropical
wave. Gentle winds prevail elsewhere. Seas are in the 5-8 ft
range off Baja California Norte, and 4-6 ft over the remainder of
the open waters off Mexico. Seas are in the 2-3 ft range over the
Gulf of California. 

For the forecast, high pressure will build west of the area 
along with a slightly deeper low pressure over the lower Colorado
River. This pattern will support fresh NW winds and building 
seas in NW swell off Baja California Norte through Monday, then 
subsiding thereafter. Farther south, moderate to fresh SE winds 
and occassionally rough seas are expected off Guerrero and 
Michoacan Tue, and off Colima and Jalisco Wed. 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 winds are over and downwind the Gulf of Papagayo, with 
light to gentle winds elsewhere north of the monsoon trough. 
Moderate to locally fresh winds are between the Galapagos 
Islands and Ecuador, with light to gentle winds elsewhere south 
of the monsoon trough. Seas are in the 4-6 ft range, except 7-8 
ft near the Galapagos Islands. 

For the forecast, southerly swell to 8 ft near the Galapagos 
will move into the far offshore waters of western Panama by late 
Tue, then subside across the region through mid week. Elsewhere, 
gentle to moderate winds and moderate combined seas will persist.

...REMAINDER OF THE AREA...

The pressure gradient between a broad ridge north of the area 
and lower pressure within the monsoon trough is supporting 
moderate winds and seas of 5-7 ft in mixed swell north of the 
monsoon trough west of 120W. Light to gentle winds are noted 
elsewhere north of the monsoon trough. South of the monsoon 
trough, moderate winds and seas of 5-7 ft prevail. 

For the forecast, seas to 8 ft in S long- period swell will 
linger around the equator through most of the week, with this 
swell bringing rough seas south of 05N into mid week. Northerly 
swell will move into the northern waters north of 28N tonight, 
with seas greater than 8 ft continuing through at least the 
middle of the week. From tonight through Tue, SW winds will 
increase slightly into the monsoon trough from 05N to 10N 
between 95W and 110W, leading to rough seas.
