Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Sat Sep 26 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
1500 UTC. 

...TROPICAL WAVES...

The axis of a tropical wave is near 94W N of 03N, moving 
westward at 10 kt. Scattered moderate to isolated strong
convection is from 12N to 15N between 92W and 95W, and from 14N
to 16N between 94W and 100W.

The axis of a tropical wave is near 105W N of 03N, moving 
westward at 10 kt. Scattered moderate convection is from 09N to
12N between 100W and 105W.

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

The monsoon trough extends from 11N86W to 12N103W to 11N120W to 
11N140W. Scattered moderate convection is from 02N to 05N E of
80W, and from 10N to 12N W of 135W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A weak ridge west of Baja California will maintain moderate NW 
to N winds across the region. Northwesterly swell propagating 
across the waters off Baja California Norte will spread southward
to the remainder of the Baja California offshore waters through 
tonight. This swell will subside Sun through early next week. 
Light to gentle winds are expected farther south the next several
days. 

Gulf of Tehuantepec: A gale to near strong force gap wind event 
is possible in the Gulf of Tehuantepec by the middle of next 
week.

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

Moderate southerly flow prevails S of the monsoon trough, with 
gentle winds north of the monsoon trough. Combined seas are 
currently 5 to 7 ft in a mix of wind waves and southerly swell. 
Long period SW swell will impact the waters between Ecuador and
the Galapagos Islands on Sun, building seas to 8 ft. This swell 
event will continue to propagate northward reaching the offshore
waters of Central America by early next week with seas building
to 6 to 8 ft.

REMAINDER OF THE AREA...

The remnant low of former tropical cyclone Lowell is centered
near 21N134W. Only moderate scattered showers are noted within 
120 nm east semicircle of the low. Seas continue to peak near 15
ft based on altimeter data, in a combination of locally generated
seas mixing with long period NW swell. The remnant low will 
continue to shift westward, moving west of the area late Sun. 
Seas in the vicinity of the remnant low will remain in the 8-12 
ft this weekend. Conditions will improve early next week as the 
remnants of Lowell shift W of 140W and as the remaining northerly
swell decays.

Southerly swell will propagate N of the equator this weekend,
building seas to 8-10 ft between 100W and 120W. These seas will 
gradually decay early next week.
