1005 UTC Sat Dec 23 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
0745 UTC.

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

The monsoon trough extends from 06N77W to 05N92W. The ITCZ 
extends from 05N92W to 06N140W. Scattered moderate and isolated 
strong convection is noted from 04N to 10N between 126W and 
140W.

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

A cold front extends from from the central Gulf of California SW
to around 23N118W. Moderate to fresh W to NW winds are occurring
behind the front. Strong N to NE winds prevail across the Gulf 
of Tehuantepec, with seas to 10 ft. Otherwise, a weak pressure 
gradient prevails across the area with mainly light to gentle 
winds occurring. Seas average 3 to 6 ft, except 6 to 8 ft
offshore Baja California Norte in NW swell. Seas in the Gulf of 
California are 2-3 ft. 

For the forecast, the cold front will continue to move SE 
through waters W of Baja California and in the Gulf of 
California today before gradually dissipating tonight. Strong 
winds will prevail across the Tehuantepec region today, with 
seas to 10 ft. Elsewhere, winds across the area will be moderate 
or weaker. High pressure building over the U.S. Great Basin 
should funnel fresh to locally strong NW winds over the Gulf of 
California Mon through Tue night. NW swell will propagate 
southeastward across the waters west of Baja California through 
tonight before diminishing. The next set of large NW swell will 
move into the Baja California Norte waters Sun through Mon.

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

A significant pressure gradient in the area continues to support
fresh to strong NE winds over the Gulf of Papagayo region. Seas 
are 6 to 8 ft within this area. Fresh N winds are also occurring
over the Gulf of Panama. Elsewhere, winds are moderate or 
weaker. N swell associated with gap winds in the Gulf of
Tehuantepec has decayed enough offshore Guatemala such that seas
are now below 8 ft 

For the forecast, fresh to strong NE winds will prevail over the
Gulf of Papagayo region into tonight. Fresh N winds will 
continue pulse over the Gulf of Panama through the weekend. 
Elsewhere, winds are expected to be moderate or weaker for the 
next several days. 

...REMAINDER OF THE AREA...

NW swell with seas of 8 to 10 ft are continuing to impact the 
waters north of 08N and west of 119W. These seas will gradually 
diminish into tonight, but remain above 8 ft through Sun. Winds 
in this area are generally moderate to fresh and NE. Elsewhere, 
the trades are moderate or weaker with seas 5-7 ft.

For the forecast, the NE trades will weaken to moderate across 
the waters by tonight. A new set of significant NW swell will 
arrive in the NW waters Sun, with seas Sun night and Mon 
exceeding 12 ft as the swell propagates SE through early next 
week.
