Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2017 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 1800 UTC surface analysis and satellite imagery through
2205 UTC.

...TROPICAL WAVES...

A tropical wave is N of 04N with axis near 90W, moving west at 
10 to 15 kt. Scattered moderate convection is N of 09N between 
87W and 97W.
 
A tropical wave extends from 03N to 16N with axis near 100W, 
moving west at 10 kt. Scattered moderate isolated strong 
convection is from 08N to 14N between 98W and 108W. 

A tropical wave extends from 04N to 17N with axis near 120W, 
moving west at 10 to 15 kt. A 1008 mb low pressure accompanies 
this wave near 12.3N120W. Scattered moderate to isolated strong 
convection is noted from 08N to 16N between 116W and 130W.

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

The monsoon trough extends from 09N84W to 15N104W to 12N120W to 
09N140W. Scattered moderate convection is N of 03N east of 81W, 
from 12 to 19N between 103W and 115W, and from 09N to 12N 
west of 132W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure west of Baja California will support moderate to 
locally fresh NW winds mainly north of Punta Eugenia through Fri 
night. A surface trough will prevail along the Baja Peninsula 
and will support moderate to locally fresh southerly winds over 
the northern Gulf of California through Fri night. These winds 
will increase to fresh to strong as the area of low pressure 
deepens. 

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. This pattern will maintain scattered 
thunderstorms and gentle to moderate southerly winds in the 
region and coastal areas. 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 16N. 
The pressure gradient between the ridge and the monsoon trough 
is supporting moderate NE trade winds north of the monsoon 
trough west of 115W, which is well depicted by earlier ASCAT 
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.
