Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Tue May 30 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

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

The monsoon trough extends from 10N75W to 11N97W to 08N120W to 
04.5N126W. The ITCZ continues from 04.5N126W to beyond 00N140W. 
Scattered moderate to strong convection is noted from 01N to 12.5N
E of 104W, and from 07N to 10N between 121W and 127W. 

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

Mainly moderate northwesterly winds prevail W of the Baja 
Peninsula this morning, except for fresh winds within 120 nm of 
the coast of Cabo San Lucas. Light and variable winds prevail
across most of the Gulf of California, except for moderate to
fresh SW gap winds across northern portions. Gentle to moderate
NW to W winds are noted elsewhere over the open waters off 
Mexico. Seas are 4 to 6 ft in S swell over the open waters off 
Mexico. Seas of 3-4 ft are noted over the northern Gulf of 
California. Seas of 1-2 ft are elsewhere over the Gulf, except 
the entrance to the Gulf where seas of 4-5 ft are noted. 

For the forecast, the pressure gradient between subtropical 
Pacific high pressure centered N of the Hawaiian Islands and a 
surface trough in the Gulf of California will support pulses of 
fresh winds during the overnight and early morning hours west of 
the Baja Peninsula. Fresh to strong S to SW gap winds will 
briefly occur in the northern Gulf of California each night 
through the forecast period. Seas of 4-6 ft in mixed swell will
persist across the Mexico offshore waters through the week. 

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

Gentle to locally moderate S winds prevail in the Ecuador and 
Galapagos Islands offshore waters. Light to gentle winds prevail
elsewhere. Seas are in the 4-6 ft range.

For the forecast, little change is anticipated through the week.

...REMAINDER OF THE AREA...

High pressure prevails over the northern waters, centered on a
1033 mb Pacific high located N of the Hawaiian Islands near 42N.
The pressure gradient between this area of high pressure and 
lower pressure in the vicinity of the ITCZ is supporting moderate
to locally fresh winds N of the ITCZ to near 16N and W of 118W. 
Gentle to locally moderate moderate winds are noted S of the 
monsoon trough and E of 115W. Light to gentle winds are noted 
elsewhere. Seas range from 5-8 ft S of 15N and 4-6 ft N of 15N.

For the forecast, no major changes are expected. The ridge will 
continue to dominate the region north of 10N and west of 110W 
through mid-week. Mainly moderate NE trade winds will persist 
across the southern periphery of the ridge, especially west of 
120W, and some fresh E winds are expected just N of the ITCZ. A 
new pulse of cross equatorial S to SW swell will approach the 
eastern tropical Pacific Wed.
