Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0900 UTC Mon Aug 5 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 0600 UTC surface analysis and satellite imagery through
0900 UTC. 

...TROPICAL WAVES...

The axis of a tropical wave is near 85W to the north of 04N, 
moving W around 10 kt. Scattered moderate and isolated strong 
convection is noted from 07N to 09N between 83W and 85W.

The axis of a tropical wave is near 101W/102W to the north of 
04N, moving W around 10 kt. Scattered moderate and isolated 
strong convection is noted from 07N to 13N between 97W and 106W.

The axis of a tropical wave is near 122W from 04N to 18N, moving
W around 10 kt. Scattered moderate and isolated strong 
convection is noted from 08N to 14N between 114W and 125W.

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

The monsoon trough extends from 09N84W to 08N95W to 12N120W to 
11N140W. Scattered moderate and isolated strong convection is 
noted from 03N to 07N E of 79W. Scattered moderate convection is
noted from 06N to 10N between 125W and 133W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A high pres ridge prevails across the forecast waters west of the
Baja California peninsula, producing gentle to moderate NW flow 
off the coast of Baja California. The ridge will prevail across
these waters through the week, with little change in wind and 
sea conditions. Southerly swell will spread across the waters S 
of 20N today, and linger through the middle of the week before 
subsiding.

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

Gentle to moderate S to SW winds south of the monsoon trough 
will increase to moderate to fresh Tue through Thu. Moderate to 
locally fresh NE winds will prevail north of the monsoon trough 
near the Gulf of Papagayo region for the next several days. Seas 
will build greater than 8 ft over the southern waters later this
week as a fresh set of long period southerly swell propagates 
into the region.

REMAINDER OF THE AREA...

The remnant low of Gil is centered near 15N128W. Winds associated
to this remnant low have diminished to 20 kt or less. There
remains some lingering seas to 9 ft within 150 NM N quadrant of
the low. Seas will continue to subside, and are expected to fall
below 8 ft by late tonight. 

Elsewhere, high pressure prevails across the forecast waters 
north of 20N. There is a locally tighter pressure gradient
between the remnant low of Gil and this area of high pressure. 
Overnight ascat pass indicates an area of moderate to fresh winds
within 390 NM NW of the remnant low due to this gradient. Gentle
to moderate winds prevail elsewhere. Southerly swell covers much
of the region south of 20N. A recent altimeter pass shows seas 
to 8 ft have pushed N of the equator between 93W and 120W. Seas 
of 8 ft or greater associated with this swell will continue to 
propagate northward, and will reach as far north as 10N between 
93W and 105W by late Tue night. Looking ahead, another set of
long period southerly swell will propagate across the equator
later this week. This swell will spread across the waters S of
20N through the weekend.
