Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Sat Aug 1 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 
0300 UTC.

...TROPICAL WAVES...

A tropical wave axis is along 92W, north of 02N to Guatemala, 
moving west at 15 kt. Isolated showers are near the wave axis.

A tropical wave axis is along 104W/105W, from 01N to 17N, moving 
west at 15 kt. Scattered moderate isolated strong convection is 
from 09N to 15N between 100W and 107W.

A tropical wave axis is along 115W, from 02N to 18N, moving west 
at 15 to 20 kt. Scattered moderate isolated strong convection is 
from 07N to 18N between 111W and 119W.

A tropical wave axis is along 132W, from 01N to 17N, moving west 
at 15 kt. Isolated showers are near the wave axis.

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

The monsoon trough axis extends from 08N78W to 11N104W to 
08N118W to 12N131W to 12N140W. Scattered moderate isolated 
strong convection is noted from 06N to 19N between 100W and 120W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

The pressure gradient between a weak ridge and an elongated 
trough that stretches from the southwestern U.S. into NW Mexico 
will continue to support moderate to fresh northwest winds west 
of Baja California Norte overnight along with 4-6 ft seas. 
Moderate to fresh southerly winds are expected in the northern 
Gulf of California through Wed. Fresh northerly wind pulses are 
expected in the Gulf of Tehuantepec region this weekend.

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

A monsoon trough axis, roughly along 08N to 09N east of 90W is 
expected to increase convective activity near and west of Panama 
and Costa Rica during the next couple of days, with the added 
energy from weak tropical waves migrating westward across this 
area. Moderate southerly winds will prevail south of the monsoon 
trough through Wed.

REMAINDER OF THE AREA...

A weak ridge extends over the waters north of 15N. The gradient 
between the ridge and the monsoon trough is supporting moderate 
northeast trade winds north of the trough axis west of 115W. A 
shrinking area of cross-equatorial southeast swell producing 7 
to 9 ft seas is located south of 15N and west of 130W. This area 
of swell will gradually shift west of 140W by Sat evening.
