NWS National Hurricane Center Miami FL
2205 UTC Sun Nov 8 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 1800 UTC surface analysis and satellite imagery through
2150 UTC. 

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

The monsoon trough extends from 13N91W to 09N111W to beyond 
09N140W. Scattered moderate convection is noted within the 
monsoon trough between 95W and 109W and scattered moderate 
to isolated strong convection further west from 07N to 11N 
between 132W and 140W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

The front weaken to a stationary front from 27N110W to Baja 
California Sur. Fresh to strong northwest gap winds will prevail
in the northern Gulf of California tonight through Mon, while 
fresh NW winds will continue across the offshore waters of Baja.
The NW swell associated with the front is increasing combined 
seas west of the Baja California. Peak seas may reach as high as
14 ft off Baja California Norte through today and gradually 
subside through Tue. A secondary front will move through the 
area tonight increasing the NW winds across the Gulf to 
fresh/strong. These conditions will continue through Mon 
morning.

Gulf of Tehuantepec: Latest ASCAT suggests northerly gap winds 
have diminished across the region showing northerly moderate 
to fresh winds, with associated seas less than 8 ft. SW swell 
will prevail across the area through the forecast period. 

Gentle winds will persist south of Cabo Corrientes outside of 
the Gulf of Tehuantepec. Gentle to moderate NW winds are 
expected from Puerto Vallarta to Manzanillo through today, with 
seas subsiding to 4-6 ft.

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

Seas are in the 5 to 7 ft range in this area, in a mix of SW 
cross-equatorial swell and NW swell. Moderate SW winds will 
prevail across the region through the forecast period. 

REMAINDER OF THE AREA...

A cold front extends from 27N110W to 22N113W. The front will 
continue to push southward through the afternoon, then stall 
and dissipate along 20N on Mon. A secondary front will move 
across the same area starting this evening, enhancing N to NW
winds across the eastern portion of the basin. Expect fresh to
strong N to NW winds and large NW swell accompanying this cold
front through early next week. Seas greater than 8 ft will 
prevail over most of the area north of 12N and west of 110W 
through mid-week. 

The remnant low of Post-Tropical Cyclone Odalys continues to be 
a well defined low-level cloud swirl near 13N128W. The low will 
continue moving westward today and gradually weaken to a trough 
as it reaches cooler waters and drier more stable air.

Surface ridging dominates north of 18N, anchored by a 1034 mb 
high pressure well to the north of the area. Moderate to fresh NE
to E winds persist across the whole area.
