Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0900 UTC Wed Nov 20 2019

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...

The axis of a tropical wave is near 92W N of 04N, moving W at 10
kt. Scattered moderate isolated strong convection was noted from
08N to 11N between 88W and 92W.

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

The monsoon trough extends from 09N78W to 10N90W to 08N99W to
12N110W to 11N120W. The ITCZ extends from 11N120W to 11N135W to
10N140W. Scattered moderate isolated strong convection was noted
from 07N to 16N between 103W and 114W. Scattered moderate
convection was noted from 08N to 11N between 125W and 140W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 

SW winds to near gale force will prevail across the northern 
Gulf of California today. A cold front has entered the offshore 
waters, and will shift southward across the Baja peninsula 
through Fri where it will stall and dissipate. Long period NW 
swell in the wake of the front will spread SSE into the offshore 
waters west of the Baja California Norte through Fri. 

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

Fresh to strong NE-E winds are expected across the Gulf of 
Papagayo Wed through Thu with seas building to around 7 ft. 
Elsewhere, gentle to moderate southwest monsoonal flow will 
continue across the offshore waters of Costa Rica, Panama, 
Colombia, and Ecuador for the next several days. 

REMAINDER OF THE AREA...

The remnant low of Tropical Depression Twenty-One-E is near 
12N111W. These remnant low is forecast to gradually shift W 
across the tropics for the next few days. Easterly winds to 
around 20 kt could persist across the N semicircle of this low 
during this time. 

Elsewhere a ridge dominates the north waters mainly N of 16N W 
of 125W. The pressure gradient between the ridge and lower 
pressure in the vicinity of the ITCZ is supporting moderate to 
locally fresh winds north of the ITCZ and west of 125W. 

A set of large, long period NW swell is forecast to reach the 
forecast waters north of 20N west of 130W Thu night, with seas 
peaking near 12 or 13 ft by Fri.
