Tropical Weather Discussion
NWS National Hurricane Center Miami FL
002 UTC Sat Aug 31 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 0000 UTC surface analysis and satellite imagery through
0230 UTC. 

...TROPICAL WAVES...

The axis of a tropical wave is near 105W from 03N to 17N, moving
W at 10 kt. Scattered moderate isolated strong convection is 
noted from 06N to 16N between 98W and 110W. This wave will be 
monitored for the potential of tropical cyclogenesis early next 
week when atmospheric conditions start to become more favorable.

The axis of a tropical wave is near 122W from 04N to 18N, moving
W at 15 kt. Scattered moderate isolated strong convection is 
noted from 11N to 18N between 117W and 125W.

The axis of a tropical wave is near 131W from 04N to 16N, moving
W at 10-15 kt. Scattered moderate isolated strong convection is 
noted from 08N to 10N between 130W and 133W.

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

The monsoon trough extends from 07N78W to 11N104W to 10N111W to 
13N121W to 10N130W. The ITCZ extends from 09N132W to 09N140W. 
Scattered moderate convection is noted from 05N to 08N between 
85W and 96W, and from 05N to 10N between 110W and 117W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface trough will persist in the Gulf of California through 
the middle of next week with moderate to fresh SE winds over the 
weekend and light to gentle variable winds the remainder of the 
forecast period. Surface high pressure west of Baja California 
will support light to moderate NW winds with the highest winds N 
of Punta Eugenia. Nocturnal northerly drainage flow in the Gulf 
of Tehuantepec will pulse to fresh to locally strong through Mon.

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

Moderate NE to E gap winds will pulse at night across the Gulf 
of Papagayo region through the middle of next week. Light to 
gentle winds are expected elsewhere N of the monsoon trough. 
Gentle to moderate S to SW winds will prevail S of the monsoon 
trough. 

REMAINDER OF THE AREA...

High pressure of 1020 mb centered near 28N138W continues to 
support moderate to fresh winds between the monsoon trough/ITCZ 
and 20N. Seas of 4 to 7 ft prevail across most of the region.

The high is forecast to linger and weaken through the weekend, 
while a weak cold front stalls near 30N140W. There is the
potential for tropical cyclogenesis next week associated with the
tropical wave near 106W.
