Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Fri Aug 30 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 
1400 UTC. 

...TROPICAL WAVES...

A tropical wave is from 10N to 20N with axis along 105W, moving 
W at 15 to 20 kt. Numerous moderate isolated strong convection 
is from 17N to 23.5N between 105W and 108W. Scattered moderate 
isolated strong convection is elsewhere from 10N to 17N between 
100W and 106W.

A tropical wave is from 04N to 16N with axis along 118W, moving 
W at 15 kt. Scattered moderate isolated strong convection is 
from 11N to 18N between 114W and 124W.

A tropical wave is from 04N to 16N with axis along 126W, moving 
W at 10-15 kt. Isolated moderate convection is from 08N to 13N 
between 122W and 127W.

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

The monsoon trough extends from 08N78W to 08N83W to 09N110W to 
11N116W to 09N134W. The ITCZ axis continues from 09N135W to 
09N140W. Scattered moderate convection is from 05N to 10N east 
of 100W, from 06N to 12N between 108W and 117W, and from 05N 
to 10N W of 133W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A elongated area of low pressure will persist in the Gulf of 
California through the middle of this coming week with moderate 
to fresh SE over the weekend and light to gentle variable winds 
the remainder period. Seas will range between 1 to 3 ft. 

Across the offshore waters west of Baja California, surface high 
pressure W of the area will support light to moderate NW winds, 
being the highest winds N of Punta Eugenia. Seas will range from 
3 to 5 ft.

Otherwise, nocturnal northerly drainage flow in the Gulf of 
Tehuantepec will pulse to fresh to strong through Mon. Seas will 
increase to 6 to 8 ft at the peak of these winds each early 
morning.

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

Moderate to fresh NE to E gap winds will pulse at night across 
the Gulf of Papagayo region through Sat. Seas of 4 to 5 ft are 
expected during the gap winds event. 

Light to gentle winds are expected elsewhere N of the monsoon 
trough, and gentle to moderate S to SW winds S of the monsoon 
trough. 

REMAINDER OF THE AREA...

High pressure centered near 28N131W continue to support moderate 
to fresh winds between the monsoon trough/ITCZ and 20N as 
depicted by latest scatterometer data. Altimeter data show seas 
of 4 to 7 ft across most of the region supported by a component 
of long period southerly swell.

The high is forecast to linger and weaken through the weekend, 
while a weak cold front stalls near 30N140W. Model guidance 
indicates potential for a weak low pressure area to develop this 
weekend into early next week along a tropical wave as it moves 
through the west central waters. Otherwise, little change in 
marine conditions across the trade wind belt is expected.
