Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 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 0000 UTC surface analysis and satellite imagery through
0240 UTC. 

...TROPICAL WAVES...

The axis of a tropical wave is near 93W N of 03N, moving 
westward at 10 kt. Convection is described below.

The axis of a tropical wave is near 103W/104W N of 03N, moving 
westward at 10 kt. 

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

The monsoon trough extends from 12N87W to 11N131W. The ITCZ 
continues from 11N131W to 11N140W. Scattered moderate and 
isolated strong convection is noted N of 02N between 80W and 90W.
Scattered moderate convection is noted from 10N to 15N between 
90W and 100W, from 08N to 12N between 100W and 120W, and from 10N
to 12N between 120W and 128W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Weak ridging is west of Baja California, maintaining moderate NW
to N winds across the region. Northwesterly swell is propagating
across the waters off Baja California Norte. This swell will 
spread southward to the remainder of the Baja California offshore
waters through Sat night. This swell will decay Sun through 
early next week.

Light to gentle winds are expected farther south the next 
several days, except pulsing moderate northerly winds in the 
Gulf of Tehuantepec tonight. Otherwise, seas of 4-7 ft are 
expected through the early part of the weekend, building slightly
to 5-8 ft in long period NW swell thereafter.

A gale force gap wind event is possible in the Gulf of 
Tehuantepec 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 southerly to southwesterly swell will impact the 
waters W of Ecuador by the end of this weekend, spreading to the
waters west 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 21.5N131.5W. Only moderate scattered showers are noted
within 120 nm east semicircle. Seas continue to peak near 14 ft
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 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 130W. These seas will
gradually decay early next week.
