Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Sat Nov 7 2020

Tropical Weather Discussion for the eastern Pacific Ocean from
the Equator to 32N, east of 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
1550 UTC. 

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

The monsoon trough extends from 12N87W to a 1008 mb low pressure
Near 13N92W to 07N121W, then resumes from 11N126W to 09N131W.
The ITCZ continues from 09N131W to beyond 09N140W. Scattered 
moderate convection is noted from 11N-14N between 95W-99W. 
Scattered moderate isolated strong convection is evident from 
08N to 12N between 130W and 140W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A strong cold front extending from 32N114W to beyond 26N119W 
will induce fresh to strong northwest to westerly gap winds in 
the northern Gulf of California through tonight, and fresh NW 
winds across the offshore waters of Baja. Large NW swell 
associated with the front will rapidly increase combined seas 
west of the Baja California through Sun. Peak seas may reach as 
high as 14 ft off Baja California Norte by Sun.

Gulf of Tehuantepec: Northerly gap winds are expected to
gradually diminish across the region today, with associated seas
subsiding to less than 10 ft by this evening. Swell generated in
this region is producing a large area of high seas that are 
combining with SW cross-equatorial swell. 

Gentle winds will persist south of Cabo Corrientes outside of 
the Gulf of Tehuantepec. NW winds are expected to remain at 
10-15 kt from Puerto Vallarta to Manzanillo through the weekend, 
with seas subsiding to 4-6 ft Sat and Sun as SW swell subsides.

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

Tropical Depression Eta in the NW Caribbean Sea is enhancing SW
wind flow into Central America from Costa Rica to El Salvador. 
Seas are 7 to 9 ft in this area, in a mix of SW cross-equatorial
swell and NW swell spreading out from Tehuantepec. Winds and 
seas will diminish today as Eta moves away. Moderate to locally 
fresh SW winds will prevail across the region through Sun, then 
subsiding Sun night and Mon.

REMAINDER OF THE AREA...

A strong cold front moving into the northern waters extends from
29N115W to 27N119W and starts to dissipate from 26N121W to 
25N140W. The front will push southward through Sun, then stall 
and dissipate along 20N on Mon. 

Fresh to strong N to NE winds and large NW swell will accompany 
the front today through early next week. This swell will mix with
the lingering swell from Odalys and produce seas greater than 8 
ft for most of the area north of 12N and west of 110W by early 
next week.

The remnant low of Post-Tropical Cyclone Odalys is now a well 
defined low-level cloud swirl. The remnants of Odalys will move 
west-southwestward through tonight and gradually weaken to a 
trough as it reaches cooler waters and drier more stable air.

Ridging dominates north of 20N, anchored by strong high pressure
well to the north of the area. Moderate to fresh NE trade winds 
persist from 10N to 20N, while moderate to fresh N to NE winds 
prevail N of 20N and W of 118W, ahead of the cold front.
