Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 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 0600 UTC surface analysis and satellite imagery through
0800 UTC.

...TROPICAL WAVES...

The axis of a tropical wave is near 82W 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 102W 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/114W from 04N to 16N, 
moving west at 10 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 05N to 10N between
87W and 97W, from 08N to 14N between 104W and 121W, and from 04N
to 10N between 125W and 140W.

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

Gentle to moderate winds are west of Baja California Norte.
Moderate winds are over the Gulf of Tehuantepec. Light to 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 today, decreasing 
thereafter. 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 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 south of the
monsoon trough. Seas are in the 4-6 ft range, except 7-9 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 over the waters north of 28N, with seas greater than 8 ft,
will continue through at least the middle of the week. SW winds 
will increase slightly into the monsoon trough from 05N to 10N 
between 95W and 110W through Tue, leading to rough seas.
