Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Sun Jun 11 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
2140 UTC.

...TROPICAL WAVES...

A tropical wave is along 91W north of 01N, moving west at 5-10 kt.
Scattered moderate convection is from 01N to 11N between 86W and
95W.

A tropical wave is analyzed along 108W from 02N to 13N, moving 
west at 10 kt. Scattered moderate convection is from 05N to 12N 
between 106W and 115W.

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

The monsoon trough extends from 11N86W to 10N100W to 08N117W. 
The ITCZ continues from 08N118W to 07N130W to beyond 07N140W. 
Outside of the convection associated with the tropical waves, 
scattered moderate convection is evident from 05N to 14N between
97W and 106W, from 05N to 10N between 116W and 125W, and from 04N
to 10N W of 130W.  

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

Fresh to locally strong SW gap winds are over the northern Gulf 
of California with seas to 4 ft. These winds are the result of a 
tightening pressure gradient between lowering pressures across 
the southern Colorado River valley and surface ridging extending 
across the Baja California offshore waters. Moderate to fresh NW
winds are over the Baja Peninsula offshore waters between Puerto
Escondido and Cabo San Lucas with 4 to 6 ft seas in mixed S and 
NW swell. Light to gentle variable winds are elsewhere in the  
Gulf of California and in the S and SW Mexican offshore waters. 
Seas are 4 to 5 ft, except 1 to 3 ft in the Gulf of California. 

For the forecast, fresh to strong SW gap winds pulsing over the 
northern portion of the Gulf of California will diminish tonight
into Mon morning. Farther south, a ridge will persist between 
Baja California Sur and the Revillagigedo Islands through mid- 
week, supporting fresh winds along the coast of Baja California 
Sur mainly at night, and fresh to occasionally strong winds off 
Cabo San Lucas. Gentle winds will persist elsewhere. 

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

Light and variable winds are noted over the offshore forecast 
waters of Central America and Colombia while gentle to moderate 
southerly winds are seen mainly south of 04N, including the 
waters between Ecuador and the Galapagos Islands. Seas are 4-5 
ft in SW swell across the region, except for 4-7 ft between the 
coast of Ecuador and the Galapagos Islands, highest SW of the
Galapagos Islands.

For the forecast, the weak pressure gradient will remain in 
place across the region supporting mainly light to gentle
variable winds across the Central America offshore waters, except
for developing moderate to fresh NE gap winds in the region of 
Papagayo Tue night through Wed night. Moderate southerly winds
between Ecuador and the Galapagos Islands will diminish to light
to gentle speed on Thu. Otherwise, moderate, long-period SW 
swell will persist mainly south of 10N building seas to 7 or 8 
ft between Ecuador and the Galapagos Islands by Mon.

...REMAINDER OF THE AREA...

A 1030 mb high NW of the area extends a ridge S and SE to near
15N and 115W. This is supporting fresh winds north of 20N and 
west of 130W. Mostly moderate trade wind flow are from 08N to 
15N west of 120W. Combined seas are still 6 to 8 ft. Farther 
south, long-period southerly swell out of the southern hemisphere
is moving north of 03.4N. Moderate winds and seas are noted 
elsewhere.

For the forecast, high pressure will support fresh trade winds with
6 to 8 ft seas over the tropics west of 120W.
