NWS National Hurricane Center Miami FL
1605 UTC Sun Dec 24 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
1530 UTC.

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

The monsoon trough extends from 09N84W to 04N97W. The ITCZ 
extends from 04N97W to 06N138W. A surface trough extends from 
09N138W to 05N140W. Scattered moderate convection is noted from 
04N to 14N between 108W and 136W.

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

Gentle to moderate NW winds dominate waters N of 18N, with light
to gentle winds to the south, due to a weak pressure gradient. 
Seas average 3 to 6 ft, except 5 to 7 ft offshore Baja California
in NW swell. Seas in the Gulf of California are 2-3 ft. 

For the forecast, winds across the area will be moderate or 
weaker through today. 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
across the waters W of Baja California into today, before 
diminishing. The next set of large NW swell will begin to move 
into the Baja California Norte waters Mon night. 

...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 NE winds over the Gulf of Papagayo region, where seas are 
5 to 7 ft. Elsewhere, winds are mostly gentle, with seas of 3 to 
6 ft.

For the forecast, fresh NE winds will prevail over the Gulf of 
Papagayo region today. Fresh N winds will pulse tonight in the 
Gulf of Panama. Elsewhere, winds are expected to be moderate or 
weaker into the middle of the week.

...REMAINDER OF THE AREA...

Decaying NW swell with seas of 8 to 9 ft are continuing to 
impact the waters north of 07N and west of 120W. NE Winds in 
this area are generally moderate to fresh. 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 today. A new set of significant NW swell will arrive 
in the NW waters tonight, with seas exceeding 12 ft through Mon 
night as the swell propagates SE into the middle of next week. A 
cold front will move into the NW waters Tue, bringing strong 
winds on both sides of it as well as a reinforcing set of 
significant NW swell.
