Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Sat Jun 10 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 0600 UTC surface analysis and satellite imagery through
0820 UTC.

...TROPICAL WAVES...

A tropical wave is along 83W north of 04N, moving west at 10 kt.
This may be enhancing scattered moderate convection across the 
offshore waters of Panama and Costa Rica, and within 60 nm of the
coast of Nicaragua.

A tropical wave is analyzed near 94W north of 04N, moving west 
at 10 kt. This may be enhancing scattered moderate to isolated 
strong convection within 60 nm of the coast of Guatemala and
Chiapas in southern Mexico. 

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

The monsoon trough extends from 10N85W to 11N95W to 07N110W. The
ITCZ continues from 07N110W to 06N120W to 08N130W to beyond
07N140W. Scattered moderate convection is evident within 60 nm of
the monsoon trough between 95W and 102W, and from 05N to 09N
between 130W and 135W.

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

Moderate to fresh winds persist along the coast Baja California 
Sur between Punta Eugenia and Cabo San Lazaro, between a ridge
extending from west of the area southwestward between Los Cabos
and the Revillagigedo Islands, and a trough approaching Baja
California Norte. Combined seas are likely 4 to 6 ft off Baja
California Sur. Gentle to moderate winds and 3 to 5 ft seas
persist elsewhere over open waters. Light and variable winds and
slight seas are noted over the Gulf of California. 

For the forecast, a ridge will persist from west off Baja 
California to south of Los Cabos through early next week, 
supporting fresh winds along the coast of Baja California Sur 
mainly at night, and fresh to occasionally strong winds off Cabo 
San Lucas. Expect strong to near-gale force SW gap winds over the
northern Gulf of California tonight ahead of a trough and a 
weakening cold front moving eastward toward Baja California 
Norte. Gentle winds will persist elsewhere. 

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

Gentle to moderate S to SW winds and 4 to 6 ft combined seas in 
SW swell are over the offshore forecast waters of Central 
America, Colombia and Ecuador south of 10N, except 6 to 7 ft 
between Ecuador and the Galapagos Islands. Light and variable 
winds and combined seas of 3 to 5 ft in SW swell are evident 
north of 10N. Winds and seas could be higher near thunderstorms. 

For the forecast, a weak pressure gradient across the forecast waters
will allow for gentle to moderate winds over the offshore waters
through the forecast period. Moderate, long-period SW swell will
persist mainly south of 10N into early next week, building seas 
to 7 or 8 ft between Ecuador and the Galapagos Islands by Tue. 
Enhanced moisture across the region will favor the development of
showers and thunderstorms off southern Central America and 
Colombia through the next several days. 

...REMAINDER OF THE AREA...

A ridge dominates the forecast waters north of 15N and west of 
110W. This pattern is supporting a gentle to moderate 
anticyclonic flow across the area. Moderate to locally fresh 
trades are observed from 08N-14N and W of 120W due to the 
pressure gradient between the southern periphery of the ridge and
lower pressure in the vicinity of the ITCZ. Recent altimeter
satellite data show 6 to 8 ft combined seas within these winds. 
Elsewhere mainly light to gentle winds prevail with seas 
generally 4 to 7 ft in mixed swell. A cold front continues to
move slowly eastward over the discussion waters north of 25N and
west of 135W

For the forecast, the cold front will continue to move eastward 
across the waters north of 20N through late Sat, and dissipate as
it moves into Baja California on Sun. Moderate to fresh N to NE 
winds are expected behind the front, with seas building to 6-8 
ft. High pressure building in the wake of the front may allow for
fresh trade wind flow and slightly higher seas from 08N to 12N 
west fo 130W through late Sat. the high pressure is forecast to 
strenghten some by early next week.
