Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Sat Jun 8 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
1500 UTC.

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

The monsoon trough extends from 11N86W to 13N100W to 09N127W. The
ITCZ continues from 09N127W to 10N133W to beyond 07N140W. Clusters
of moderate to isolated strong convection are noted from 11N to
15N between 90W and 105W. Scattered moderate to isolated strong
convection can be found from 03N to 07N east of 80W to the coast
of Colombia, from 04N to 08N between 82W and 92W, and from 07N to
11N between 100W and 110W.

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

High pressure of 1021 mb located W of area near 27N142W supports
moderate NW winds across the Baja California offshore waters,
with seas of 5 to 7 ft, except N of 23N between 116W and 120W
where an altimeter pass indicates seas of 8 to 10 ft in NW swell.
Gentle to moderate winds and slight seas are present in the Gulf
of California.

Elsewhere in the Mexican offshore waters, including the Gulf of
Tehuantepec, light to gentle winds and moderate seas prevail.
Hazy conditions persist off southern and SW Mexico, including the
Gulf of Tehuantepec, due to agricultural fires over southern
Mexico and Central America, reducing visibility to around 5 nm at
times.

For the forecast, moderate NW winds and seas of 5 to 7 ft will
continue off Baja California into the middle of next week. Fresh
winds will push through the mountain gaps and reach the Gulf of
California in the night and morning hours during the next few
days. Hazy conditions caused by smoke from agricultural fires in
Mexico will continue offshore of SW and southern Mexico for the
next couple of days, reducing visibility to near 5 nm at times.

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

The monsoon trough remains located farther north than its usual
climatological position for this time of the year. This results
in gentle to moderate SW-W winds in the offshore waters of
Central America. SW swell produces seas of 5 to 7 ft across the
area described. Mainly gentle winds and moderate seas are evident
in the Gulf of Papagayo and south of the equator.

Hazy conditions persist over the offshore waters of Guatemala and
El Salvador due to smoke from agricultural fires in southern
Mexico and Central America.

For the forecast, light to gentle winds will prevail north of 10N,
while gentle to moderate winds are expected south of 10N for the
next few days. Meanwhile, hazy conditions caused by smoke from
agricultural fires over Mexico and Central America may reduce
visibilities mainly over the northern Central American offshore
waters for the next couple of days.

...REMAINDER OF THE AREA...

A 1021 mb high pressure system is centered near 27N142W and
continues to dominate the forecast waters N of 15N and W of 120W.
This is leading to gentle to moderate N to NE winds and seas of
5 to 7 ft for waters N of 20N. Moderate southerly winds and
seas of 6-8 ft are noted south of the monsoon trough and east of
115W. Elsewhere, mainly gentle winds and moderate seas are
prevalent.

For the forecast, high pressure will dominate the area while
weakening slowly over the next couple of days. Moderate to
occasionally fresh winds and seas of 8-9 ft will continue across
the eastern Pacific and expand into the central waters near and
south of the monsoon through the weekend.
