Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1210 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 0600 UTC surface analysis and satellite imagery through
1000 UTC.

...TROPICAL WAVES...

A tropical wave that is partially still in the eastern Caribbean
extends along 81W from Panama to Ecuador, moving W at 10 to 15 
kt. No significant convection is noted over Pacific waters
associated with this tropical wave at this time.

A tropical wave axis previously near 93W was relocated to the
west near 100W. The axis extends from 02N into southern Mexico, 
and is moving west at 10 to 15 kt. Numerous moderate to strong 
convection is noted from 09N to 12N between 98W and 101W.

A tropical wave is along 112W from 02N to 18N moving westward at
10 to 15 kt. No significant convection is associated with this
tropical wave.

A tropical wave extends along 133W from 02N to 18N, moving 
westward at 10 to 15 kt. No significant convection is associated
with this tropical wave.

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

The monsoon trough axis extends from 10N84W to 12N120W to 
06N135W. Aside from what is noted in tropical waves section 
above, scattered moderate to isolated strong convection is 
observed from 08N to 12N between 95W and 98W.

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 next 
week.

A deep layer trough moving into the southwest US will allow
pressure to lower north of the region by Tue. This pattern will 
support moderate to fresh winds over the northern Gulf of 
California late Tue into 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 moderate to locally 
fresh gap winds are possible in the Gulf of Tehuantepec region 
Wed through Fri nights.

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 
by Sun night. Pulses of moderate to locally fresh offshore winds
may occur in the Papagayo region Wed and Thu nights.

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 into Sun.
