Tropical Weather Discussion
NWS National Hurricane Center Miami FL
237 UTC Wed Jul 29 2020

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
0200 UTC.

...TROPICAL WAVES...

A tropical wave is along 85W, extending north of 04N through 
Costa Rica into the southwest Caribbean, moving west at 10 to 15 
kt. No significant convection is observed near the wave axis at
this time.

A tropical wave axis is along 96W north of 04N into southern
Mexico, moving west at 10 kt. No significant convection is
observed near the wave axis.
 
A tropical wave axis is along 117W, from 05N to 17N. It is 
moving west at 10 to 15 kt. Scattered moderate convection is 
from 11N to 14N between 114W and 118W near the monsoon trough.

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

The monsoon trough axis extends from 09N82W to 16N101W to 
10N140W. Scattered moderate convection is from 11N to 14N 
between 114W and 118W, and from 10N to 12N between 125W and 128W.
Scattered moderate convection is observed from 08N to 12N between
131W and 134W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure west of Baja California will support
fresh NW winds north of Punta Eugenia through Wed night, mainly
near the coast. A tightening pressure gradient over the 
southwest U.S. will support moderate to fresh winds over the 
northern Gulf of California Wed and again Sat. 

Farther south, pulses of fresh to strong gap winds are possible 
in the Gulf of Tehuantepec region Fri night through Sun night.
These winds will support seas up to 6 ft, mixing with a component
of longer period southerly swell.

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

The monsoon trough has lifted northward and has reached a 
position parallel to the coast of Central America and southern 
Mexico. This pattern will maintain scattered thunderstorms and 
gentle to moderate southerly winds through mid-week before the
monsoon trough reforms farther south. Pulses of fresh offshore 
winds are likely in the Papagayo region Tue through Fri.

REMAINDER OF THE AREA...

A ridge of high pressure extends over the waters north of 16N. 
The pressure gradient between the ridge and the monsoon 
trough/ITCZ is supporting moderate NE trade winds north of 
the monsoon trough west of 116W which is well depicted by the 
earlier scatterometer data. Seas in this region range between 5 
to 7 ft. Meanwhile, cross-equatorial southerly swell east of 125W
will support seas of 5 to 7 feet through the week.
