Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Fri Jun 2 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 1800 UTC surface analysis and satellite imagery through
2100 UTC.

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

The monsoon trough extends from 13N88W to 09N112W. The ITCZ 
continues from 09N112W to 03N140W. Scattered moderate convection
is noted from 02N to 11N between 100W and 138W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
 
Moderate to fresh NW winds are occurring elsewhere within 150 nm
of the west coast of Baja California Sur with seas of 5 to 6 ft.
Moderate NW winds prevail offshore Baja California Norte, where 
seas are 6 to 7 ft in NW swell. Gentle winds prevail across the 
Gulf of California, with seas of 2 to 4 ft. Farther S, from Cabo
Corrientes to the Guatemala border, winds are gentle to locally 
moderate from the WNW, with seas of 5-7 ft in SW swell.

For the forecast, pulses of fresh to strong winds from the 
evening through early morning hours are expected across the 
waters west of the Baja Peninsula and off Cabo San Lucas into  
next week. Fresh SW gap winds in the Gulf of California will 
pulse on Sun night through Tue night. Gentle to moderate winds 
will prevail elsewhere. The next N swell event will move through
the northern Baja California offshore waters on Mon.

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

Gentle to moderate winds prevail across the entire area. Seas 
are 5-7 ft in long period S to SW swell, except 7 to 8 ft near 
the Galapagos Islands.

For the forecast, gentle to moderate SW winds are expected S of 
the monsoon trough into early next week. Moderate SW cross 
equatorial swell will dominate regional seas through Sat before 
a new large long-period SW swell builds into the regional waters
Sat night through Mon, then decaying thereafter.

...REMAINDER OF THE AREA...

A surface high pressure ridge extends from a 1026 mb high 
pressure near 35N135W to 21N118W. The pressure gradient between 
the high pressure and lower pressure along the monsoon trough and
ITCZ is supporting fresh to strong NE winds N of the ITCZ to 
near 14N and W of 115W. Seas to 8 ft prevail with these winds. 
Gentle to moderate winds are noted elsewhere, with seas of 5-7 
ft. SW swell prevails S of 08N between 97W-120W supporting seas 
to 9 ft in this area.

For the forecast, high pressure ridge will remain in place 
through tonight, before weakening and shifting gradually 
eastward through the weekend. The current SW swell over the 
waters E of 120W and S of 10N will continue to subside through 
tonight. A new pulse of large cross equatorial SW swell will 
reach the eastern tropical Pacific Sat and build through Sun 
night, 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.
