Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Sat Jun 3 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 northern Colombia near 10N74W to
13N96W to 10N112W to 06N135W. The ITCZ continues from 06N135W to
04N140W. Scattered moderate isolated strong convection is from 
02N to 09N between 85W and 95W. Similar convection is noted from
07N to 11N between 95W and 120W, and from 04N to 10N W of 130W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
 
A ridge dominates the offshore forecast waters of Baja California
producing gentle to moderate NW to N winds, with the exception 
of moderate to fresh winds between Cabo San Lazaro and Punta 
Eugenia. Seas are 5 to 7 ft in NW to N swell. In the Gulf of 
California, winds are light and variable with seas in the 1 to 2 
ft range, expect 3 to 4 ft near the entrance to the Gulf. Gentle 
to moderate NW winds prevail across the remainder of Mexican 
offshore waters, with seas of 4 to 6 ft primarily in SW swell.

For the forecast, a ridge will continue to control the weather
pattern across the waters W of the Baja California Peninsula
through at least Mon with little change in winds and seas. A
developing low over the northern Gulf of California will support
fresh to locally strong S to SW winds at night Mon and Tue. 
Moderate NW winds across the SW Mexican offshore waters will 
diminish to light to gentle speeds on Mon.

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

Light to gentle SW to W winds are across the Central America
offshore waters while gentle to moderate southerly winds are 
noted between Ecuador and the Galapagos Islands. Seas are 4 to 6
ft in SW swell across the region, except 1 to 3 ft in the lee of
the Galapagos Islands.

For the forecast, mainly gentle to moderate S to SW winds will 
prevail. Building seas of 8 to 9 ft in SW swell will propagate 
across the waters between Ecuador and the Galapagos Islands 
tonight, reaching the offshore waters of W Panama and Costa Rica
by Sun night. 

...REMAINDER OF THE AREA...

High pressure N of the area anchored by a 1027 mb high near 
40N143W extends a ridge across the forecast waters N of 15N W of
110W generating a gentle to moderate anticyclonic flow. An area
of moderate to fresh NE winds is around the southern periphery 
oW of 125W. Seas are generally 5 to 7 ft in mixed swell. 

For the forecast, the ridge will remain in place through mid- 
week. Cross equatorial SW swell will reach the eastern tropical 
Pacific waters today building seas to 8-9 ft to the east of 120W
and south of 10N. Looking ahead, N swell is forecast to push S 
of 30N Mon through Tue building seas to 8-10 ft N of 20N and E of
135W.
