Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Thu May 30 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.

...TROPICAL WAVES...

The axis of a tropical wave is near 89W moving west at 10 to 15 
kt. Scattered moderate convection is evident within 90 nm of the
tropical wave axis from 07N to 10N. 

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

The monsoon trough extends from 10N84W to 11N103W to 08N114W. 
The ITCZ continues from 08N114W to beyond 07N140W. Scattered 
moderate convection is noted from 06N to 15N between 81W and 
93W, and from 04N to 09N between 124W and 140W.

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

High pressure prevails west of the Baja California peninsula. The
pressure gradient between the area of high pressure and a trough
over north central Mexico is supporting moderate to fresh winds 
west of the Baja California peninsula. Moderate to fresh winds
are noted in the Gulf of Tehuantepec. Light to gentle winds 
prevail over the remainder of the discussion waters. Seas are in
the 6-8 ft range off Baja California Norte, and 6 ft off Baja
California Sur. Elsewhere over the open waters off Mexico, seas
are in the 4-5 ft range. Seas of 3 ft or less are found over the
Gulf of California. Hazy conditions persist off southern Mexico,
including the Gulf of Tehuantepec, due to agricultural fires 
over southern Mexico and Central America. Visibilities may 
decrease at times to 3 nm or less. 

For the forecast, moderate to fresh NW to N winds will prevail 
off the Baja California peninsula through early next week. 
Elsewhere, light to gentle winds will prevail across the open 
waters. Seas will build to 9 ft in long period NW swell off of 
Baja California Norte tonight through Mon. Hazy conditions may 
persist off southern 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...

Moderate to fresh gap winds, locally strong, prevail across the 
Gulf of Papagayo region. Light to gentle winds are elsewhere N of
the monsoon trough. Gentle to moderate winds prevail S of the 
monsoon trough. Seas are in the 6-8 ft range in the Gulf of 
Papagayo, and 4-6 ft elsewhere. Hazy conditions continue off the 
Central American coast due to agricultural fires in southern 
Mexico and Central America. Visibilities may decrease at times to
3 nm or less. 

For the forecast, moderate to fresh E gap winds are expected across 
the Papagayo region through early Sat. 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 the next few days. 

...REMAINDER OF THE AREA...

High pressure prevails N of 20N. The pressure gradient between
the area of high pressure and lower pressure in the vicinity of
the ITCZ and within the monsoon trough is supporting moderate to
fresh winds, and seas of 6-8 ft, N of the ITCZ/monsoon trough to
near 20N and W of 120W. Northerly swell is bringing seas of 8-9 
ft to the waters N of 28N between 120W and 125W. Moderate winds, 
and seas of 5-6 ft, are elsewhere N of 20N. Gentle to moderate 
winds, and seas of 4-5 ft, are elsewhere N of the monsoon trough.
Gentle to moderate winds, and seas of 5-6 ft, prevail S of the 
ITCZ/monsoon trough.

For the forecast, little change is expected to the current
conditions over much of the area the next few days.
