Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 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 0600 UTC surface analysis and satellite imagery through
0840 UTC. 

...TROPICAL WAVES...

The axis of a tropical wave is near 93W/94W N of 03N, moving 
westward at 10 kt. Convection is described below.

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

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

The monsoon trough extends from 12N87W to 11N135W. The ITCZ 
continues from 11N135W to 11N140W. Scattered moderate and 
isolated strong convection is noted E of 80W and N of 05N between
80W and 90W. Scattered moderate convection is noted from 10N to 
15N between 90W and 100W, from 08N to 12N between 100W and 112W,
and from 10N to 12N between 120W and 130W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Weak ridging 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. 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 21N132W. Only moderate scattered showers are noted within 
120 nm east semicircle of the low. 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.
