Tropical Weather Discussion NWS National Hurricane Center Miami 
FL 1605 UTC Tue Oct 22 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 1200 UTC surface analysis and satellite imagery through 
1445 UTC.

...TROPICAL WAVES...

The axis of a tropical wave is near 99W north of 03N, moving 
west around 10 to 15 kt. No significant convection is noted with 
the wave.

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

The monsoon trough axis extends from 10N86W to 15N98W to 11N107W 
to 11N122W to 09N130W. The ITCZ extends from 09N130W to 10N140W. 
Scattered moderate convection is from 02N to 08N E of 82W, from 
07N to 12N between 89W and 96W, from 07N to 15N between 116W and 
130W, and from 07N to 11N W of 130W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 

Moderate to fresh NW to N winds will continue over the Gulf of 
California through Wed, then resume again Thu evening with fresh 
to strong winds expected for the northern gulf through Fri 
night. Light to gentle winds will prevail over the Baja 
California offshore waters through the weekend. 

Strong northerly gap winds are expected across the Gulf of 
Tehuantepec tonight, increasing to near gale force Wed morning 
with building seas to 9 ft downstream of the Gulf. This gap wind 
event is expected to end Wed night, however a stronger gap wind 
event is forecast to start Sat morning and continue through 
early next week. Gale force winds associated with this event 
are likely on Sat.

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

Seas of 4-6 ft prevail across the offshore waters of Central 
America, as well as between Ecuador and the Galapagos Islands 
along with variable light to gentle winds. South to southwest 
winds south of the monsoon trough are expected to increase to 
moderate starting Wed and continuing through the weekend. 

Otherwise, a set of long period SW swell will move northward 
into the region on Wed, but wave heights are expected to remain 
less than 8 ft.

REMAINDER OF THE AREA...

A broad region of 7-10 ft seas in NW swell persists across much 
of the waters north of 10N W of 110W based on the latest 
altimeter data. The swell will continue decaying through 
tonight, although 8-9 ft seas will linger across the northern 
waters through Wed in mixed NW swell and NE wind waves. Moderate 
to fresh NE winds continue west of 130W between the ITCZ and a 
high pressure ridge across the northern waters. Little change is 
expected over the next couple days.
