Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2121 UTC Sun Oct 6 2019

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
2100 UTC.

...TROPICAL WAVES...

The axis of a tropical wave is near 111W from 06N to 19N, moving
W around 15 kt. No significant deep convection is associated 
with this tropical wave.

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

The monsoon trough extends from 15N92W to 14N112W to a 1012 mb
low at 19N132W to a second 1012 mb low at 15N136W to beyond
14N140W. Scattered moderate and isolated strong convection is
located from 05N to 11N east of 107W. Scattered moderate
convection is located from 07N to 12N between 122W to 128W as
well as 08N to 11N west of 136W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 

A ridge will dominate the offshore forecast waters west of Baja 
California during the next several days producing gentle to 
moderate NW to N winds. High pressure forming over the Great 
Basin will bring strong NW to N winds across the northern part of
the Gulf of California on Thu and reaching the central Gulf of 
California Thu night. High pressure building behind a cold front 
moving through the Gulf of Mexico will generate strong to near 
gale N winds over the Gulf of Tehuantepec Mon through Wed 
morning. No tropical cyclone activity is expected in the region 
for at least the next several days. 

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

Gentle to moderate SW to W winds will prevail from 02N to the 
monsoon trough near 11N. Gentle to moderate S to SW winds will 
prevail over the waters between Ecuador and the Galapagos 
Islands. No significant long-period swell will affect the waters 
through at least Fri night. 

REMAINDER OF THE AREA...

Two weak low pressure systems continue over the western waters at
19N132W and 15N136W. Significant convection is no longer
occurring with these systems and both are expected to weaken to
troughs by Tue. The low to the northeast has seas to 8 ft, which
should diminish by Mon. No tropical cyclone activity is expected
for at least the next several days.

Elsewhere, a surface ridge extends southeastward from 30N122W to
20N107W. The pressure gradient between the ridge to the monsoon 
trough is supporting mainly gentle to moderate tradewinds. South
of the monsoon trough gentle to moderate S to SW winds prevail. 
Little change is expected during the next several days. Cross 
equatorial long-period SE swell continues to propagate across 
the southern waters, with seas to 8 ft between 93W and 110W. Seas
will subside below 8 ft by Mon. 

A new long-period N swell event of 8 to 10 ft is expected to
reach our northern border west of Baja California Wed night and
persist through Fri.
