Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Mon Jul 24 2023

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
2100 UTC.

...TROPICAL WAVE...

The axis of a tropical wave is near 95W from SE Mexico southward
to 02N, moving west at around 15 to 20 kt. Nearby convection is 
described below.

The axis of a weak tropical wave is near 109W, from 02N to 20N, 
moving west at around 15 to 20 kt. No significant convection is 
evident with this tropical wave.

The axis of a tropical wave is near 133W, from 02N to 18N moving
west at around 15 to 20 kt. No significant convection is evident
with tropical wave.

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

The monsoon trough extends from 09N85W to 07N90W to 07.5N100W. 
The ITCZ extends from 07.5N100W to 09N105W to 09N127W to beyond 06N140W.
Numerous moderate to scattered strong convection from 04N to 07N
east of 80W. Numerous moderate to isolated strong convection 
from 03N to 07N between 83W and 86W. Scattered moderate 
convection from 09N to 13N between 95W and 105W.

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

Scattered showers and isolated thunderstorms are lingering over 
the offshore waters of Oaxaca, associated with overnight land 
breeze activity, and ahead of the tropical wave near 95W. Moderate
to fresh N winds persist in the Gulf of Tehuantepec. Mainly 
gentle to locally moderate winds prevail elsewhere across the 
offshore waters of Mexico outside of thunderstorms.

For the forecast, expect fresh to strong at night across the 
Gulf of Tehuantepec through the middle of the week. Gentle to 
moderate winds and moderate seas will persist elsewhere, except 
for locally gusty winds near clusters of showers and 
thunderstorms in portions of the Gulf of California during 
overnight hours.

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

Numerous showers and scattered thunderstorms persist 180 to 240
nm off Costa Rica and western Panama. Moderate to fresh NE-E gap
winds are across the Papagayo region along with 4-6 ft seas. 
Gentle to moderate southerly winds are noted elsewhere, with 3-5
ft seas except in S-SW swell south of 03N.

For the forecast, fresh to strong gap winds will pulse across the Gulf
of Papagayo each night through the week, with moderate to rough
seas. Gentle to moderate winds and slight to moderate seas will
persist elsewhere, except for locally gusty winds near clusters
of showers and thunderstorms from Colombia to Costa Rica. 

...REMAINDER OF THE AREA...

Weak high pressure ridging dominates the basin N of the monsoon
trough and ITCZ, except for a surface trough along 139W N of the
ITCZ which is the remnants of T.D. Four-E. A scatterometer
satellite pass indicated moderate to fresh winds from 09N to 12N
between 127W and 131W, following the tropical wave moving through
the region. Southerly swell is supporting combined seas to near 
8 ft south of the equator between 110W and 120W. Elsewhere, 
mainly gentle to moderate winds and moderate seas prevail across 
the area.

For the forecast, seas are building in the area of fresh winds
associated with the tropical wave, and may reach as high as 8 ft
Tue with a component of southerly swell. Gentle to moderate 
winds are forecast thereafter and elsewhere. Moderate seas will 
prevail, building to around 8 ft S of the Equator and W of 95W 
through Wed.
