NWS National Hurricane Center Miami FL
1005 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 0600 UTC surface analysis and satellite imagery through 
0830 UTC.

...TROPICAL WAVES...

A tropical wave axis is along 93W/94W, north of 02N to southern 
Mexico, moving west at 15 kt. Isolated showers are near the wave 
axis.

A tropical wave axis is along 106W, from 01N to 17N, moving west 
at 15 to 20 kt. Scattered moderate to strong convection is from 
10N to 15N between 102W and 107W.

A tropical wave axis is along 116/117W, from 02N to 18N, moving 
west at 15 to 20 kt. Scattered moderate to strong convection is 
from 08N to 14N between 115W and 121W.

A tropical wave axis is along 133W, 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 in Panama to 11N86W 
near the border between Costa Rica and Nicaragua, to 09N94W to 
12N106W to 11N117W to 08N119W to 08N128W to 10N135W to 10N140W. 
Scattered moderate isolated strong convection is noted from 07N 
to 16N between 98W and 122W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A weakening pressure gradient between high pressure centered 
near 32N132W and an elongated trough that stretches from the 
southwestern U.S. into NW Mexico will support gentle to moderate 
northwest winds west of Baja California Norte, with 4-6 ft seas. 
Moderate to fresh southerly winds are expected in the northern 
Gulf of California through Wed. Fresh northerly winds will pulse 
across the Gulf of Tehuantepec region through Wed.

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

A monsoon trough axis stretches along 09N to 10N east of 90W. 
Weak tropical waves will migrate westward across Central America 
early in the week, and initiate more widespread shower activity 
in a few days.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 
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 this evening.
