Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Wed May 29 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
1430 UTC.

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

The monsoon trough extends from 10N85W to a 1010 mb low at
09N118W then extending to another 1010 mb low at 09N129W. From
there, the ITCZ extends to beyond 07N140W. Scattered moderate
convection is occurring from 08N-11N between 110W-122W.

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

A subtropical ridge extends from 30N125W to 20N112W to 15N100W.
NW to N winds east of the ridge are moderate to fresh north of
Cabo San Lucas, and elsewhere winds are gentle. Seas are 4-6 ft
over the Pacific waters and 1-3 ft over the Gulf of California.
Scattered moderate and isolated strong convection is noted north
of 13N between 93W-98W over the Gulf of Tehuantepec. First-light
Geocolor satellite imagery indicates hazy conditions from the
Gulf of Tehuantepec northwestward to Cabo Corrientes due to
agricultural fires over S Mexico and Central America.

For the forecast, the subtropical ridge will continue to support
moderate to fresh NW to N winds off the Baja California
peninsula into the weekend. Light to gentle winds will prevail
across open waters elsewhere. Expect building seas up to 10 ft
with the arrival of long period NW swell off of Baja California
Norte from tonight through Fri. Hazy conditions may persist off S
and SW Mexico, including the Gulf of Tehuantepec, due to
agricultural fires over S Mexico and Central America.

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

NE to E gap winds are moderate to locally fresh this morning over
the Gulf of Papagayo region. South of the monsoon trough, S to
SW winds are moderate to fresh are occurring. North of the
monsoon trough aside from the Gulf of Papagayo region, winds are
light to gentle. Seas are 4-6 ft across the forecast waters.
First-light Geocolor satellite imagery indicates hazy conditions
over the Guatemala and El Salvador waters due to agricultural
fires over S Mexico and Central America.

For the forecast, moderate to fresh E gap winds are forecast
across the Papagayo region through Fri morning. Elsewhere, gentle
to moderate winds will prevail for the next several days. Hazy
skies from smoke caused by agricultural fires over Mexico and
Central America may reduce visibilities over portions of the
Central American offshore waters through the next few days.

...REMAINDER OF THE AREA...

A subtropical ridge extends from 30N125W to 20N112W to 15N100W. The
pressure gradient between the ridge and low pressure along the
monsoon trough/ITCZ is forcing moderate to fresh NE trades from
08N-22N west of 120W. Elsewhere winds are moderate or weaker.
Seas are 8-9 Ft from 08N-13N west of 137W. Elsewhere seas are 5-7
ft.

For the forecast, building high pressure north of the region
will support an increased area of fresh to locally strong trade
winds, mainly from 08N to 22N west of 120W, allowing seas to
build up to 10 ft over the next few days. Meanwhile, N swell
will move into the waters north of 25N and east of 130W tonight
through Fri, with maximum seas reaching up to 10 ft. Gentle to
moderate breezes and moderate seas will persist elsewhere.
