Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Tue Oct 27 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
0845 UTC. 

...TROPICAL WAVES...

A tropical wave extends from 05N to 15N with axis near 130W, 
moving westward at 5-10 kt. There is no significant convection 
associated with this feature at this time.

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

The monsoon trough axis extends from 10N86W to 12N96W to 09N110W
to 11N128W. The ITCZ begins near 10N131W and continues beyond 
10N140W. Scattered moderate convection is within 120 nm either 
side of the both the monsoon and the ITCZ.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Strong to near gale force winds will funnel southward along the 
northern and central Gulf of California through Tue. Fresh to 
strong winds will reach the southern gulf and the entrance of the
gulf through early Wed. Seas are expected to be around 9 ft in
the northern gulf this morning. 

Mainly moderate to locally fresh northwest winds are across the 
offshore waters of Baja California with seas to 6 ft. These 
winds are forecast to continue through Wed morning associated
with the gap wind event in the Gulf of California. Strong winds 
are forecast to funnel to the waters N of Punta Eugenia today. 
Seas are expected to be in the 6-7 ft range during this period. 
Gentle to moderate winds are forecast to dominate the offshore 
waters W of Baja Wed evening through early Fri and become light 
to gentle the remainder of the period.

Light and gentle winds will prevail in the Gulf of Tehuantepec 
through Thu. The next gap wind event in Tehuantepec is forecast 
to begin Thu evening. Model guidance suggest a rapid wind 
increase to near gale force afterwards and gale force winds by
Fri afternoon. The forecast calls for the continuation of near
gale to gale force winds the remainder weekend with seas building
to 16 ft.

Winds will remain light to gentle over the SW Mexico offshore
waters, except for the offshore waters between Puerto Vallarta 
and Manzanillo where moderate to fresh northwest winds are 
expected today through Thu evening associated with the gap wind 
event in the Gulf of California. 

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

Moderate to locally fresh south to southwest winds will prevail
mainly between the monsoon trough and N of the Galapagos Islands 
through the forecast period. Seas are expected to remain in the 
5-6 ft range, increasing to 7 ft late in the week due to the 
next Tehuantepec gap wind event.  

REMAINDER OF THE AREA...

Strong high pressure N of the area extends a broad ridge 
southward into the northern forecast waters. The pressure 
gradient between the ridge and lower pressure associated with the
monsoon and the ITCZ will support the continuation of moderate 
to locally fresh NE winds over a belt approximately from 10N to 
20N W of 115W. A tropical wave along 130W is expected to move 
west of the forecast area late today.
