Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1445 UTC Sun Jul 26 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 1200 UTC surface analysis and satellite imagery through
1430 UTC.

...TROPICAL WAVES...

A tropical wave has emerged fully into the eastern Pacific and is
now located along 85W from 03N into Costa Rica, moving W at 15
kt. Scattered moderate convection has developed from 06N to 11N
between 81W and 87W.

A tropical wave axis now is now reoriented along 104W, extending
from 02N to 17N. It is moving W at 15 kt. Numerous moderate to
strong convection is noted from 08N to 12N between 98W and 105W.

A tropical wave previously along 112W has dissipated.

A tropical wave extends along 134W from 02N to 17N, moving W at
10 kt. Scattered moderate convection has developed from 03N to
10N between 132W and 140W.

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

The monsoon trough axis extends from 10N84W to 11N115W to 
06N135W. The Intertropical Convergence Zone axis extends from
06N135W to beyond 05N140W. Aside from what is noted in tropical
waves section above, scattered moderate to strong convection is 
observed from 07N to 14N between 93W and 96W. Scattered moderate
convection has also developed between 05N and 16N between 105W
and 129W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure west of Baja California will support moderate to 
locally fresh NW winds north of Cabo San Lazaro into late week.

A deep layer trough moving into the southwest US will allow 
pressure to lower north of the region Mon night. This pattern 
will support moderate to fresh winds over the northern Gulf of 
California Tue through Wed. Farther south, light breezes and 
southerly swell will persist through the period. Looking ahead, 
the monsoon trough will lift northward to off the coast of 
southern Mexico by Tue. This will support increased showers and 
thunderstorms, mainly at night. Pulses of fresh gap winds are
possible in the Gulf of Tehuantepec region Thu through Sat..

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

The monsoon trough is currently along roughly 10N, but will lift
northward early in the week to a position parallel to the coast 
of Central America. This pattern will maintain scattered 
thunderstorms and gentle to moderate southerly winds. Meanwhile 
long period SW swell will gradually subside off Central America 
this evening. Pulses of fresh offshore winds may occur in the 
Papagayo region Wed through Fri.

REMAINDER OF THE AREA...

A ridge of high pressure extends over the waters north of 20N. 
The pressure gradient between the ridge and the monsoon
trough/ITCZ is supporting moderate NE trade winds north of the 
monsoon trough west of 120W with seas in the 5 to 7 ft range. 
Meanwhile, cross- equatorial southerly swell will continue to 
move into region, occasionally supporting combined seas nearing 8
ft east of 115W today.
