Tropical Weather Discussion
NWS National Hurricane Center Miami FL
942 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 0600 UTC surface analysis and satellite imagery through
0800 UTC.

...TROPICAL WAVES...

A tropical wave is along 86W/87W, extending north of 04N through
Nicaragua, moving west at 10 to 15 kt. Scattered moderate
convection is noted from 11N to 13N between 88W and 91W.

A tropical wave axis is along 98W north of 03N into southern
Mexico, moving west at 10 kt. No significant convection is
observed near the wave axis.
 
A tropical wave axis is along 118W, from 03N to 17N. It is 
moving west at 10 to 15 kt. Scattered moderate to isolated strong convection
is from 10N to 13N between 115W and 122W near the monsoon 
trough.

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

The monsoon trough axis extends from 08N83W to 10N95W to 15N107W
to 10N140W. Scattered moderate convection is observed from 11N to
13N between 100W and 103W. Scattered moderate to isolated strong
convection is from 10N to 13N between 115W and 122W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure west of Baja California will support fresh NW winds
north of Punta Eugenia through tonight. A tightening pressure 
gradient over the southwest U.S. will support moderate to fresh 
winds over the northern Gulf of California today 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 along the
coast of Central America and southern Mexico. This pattern will
maintain scattered thunderstorms and gentle to moderate
southerly winds. Pulses of fresh offshore winds are likely in
the Papagayo region through Fri. 

REMAINDER OF THE AREA...

A ridge of high pressure extends over the waters north of 15N. 
The pressure gradient between the ridge and the monsoon 
trough/ITCZ is supporting moderate NE trade winds north of 
the monsoon trough west of 115W 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.
