NWS National Hurricane Center Miami FL
1005 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 0600 UTC surface analysis and satellite imagery through
0730 UTC.

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

The monsoon trough extends from 08N81W to 05N95W. The ITCZ 
extends from 04N96W to 06N135W. A surface trough extends from 
09N137W to 04N139W. Scattered moderate convection is noted from 
05N to 11N between 108W and 131W.

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

Moderate N winds prevail across the Gulf of Tehuantepec. 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 to locally strong 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 123W. 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 today. A new set of significant NW swell will arrive 
in the NW waters later today, with seas tonight through Mon 
night exceeding 12 ft 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.
