Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1500 UTC Thu Nov 8 2018

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 
1500 UTC. 

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

The monsoon trough extends from 08N78W TO 09N110. The ITCZ 
extends from 09N114W to 06N140W. Scattered moderate convection 
is noted within 60 nm of the monsoon trough between 92W and 
103W. 

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 

A ridge extends from 1032 mb high pressure west of California 
southeastward to near Baja California Sur at 22N112W. The ridge 
will prevail over this area the next few days. A light to gentle 
anticyclonic flow around this ridge will prevail west of the 
Baja California Peninsula, with seas less than 8 ft in NW swell. 

Gulf of California: High pressure is building over the Great 
Basin region today. This will help induce fresh to strong 
northerly winds over the northern Gulf early Fri through Sat 
morning, with seas building to 10 ft. Winds will then diminish 
to 15 kt or less Sat night and Sun.

Gulf of Tehuantepec: A cold front will shift across the Gulf of 
Mexico and reach the Bay of Campeche by Sat morning. This will 
help usher in the next gap wind event across Tehuantepec. Winds 
are forecast to increase briefly to near gale force late Saturday
then diminish on Sun.

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

Light to gentle winds are forecast north of the monsoon trough. 
Gentle to moderate southwest monsoon flow is expected south of 
the monsoon trough. Long period SW swell of up to 6 ft will 
continue to impact the waters off Panama and Costa Rica through 
late today before subsiding. Another round of modest cross 
equatorial SW swell is expected to move into the region Fri 
afternoon, and last though the weekend. 
   
REMAINDER OF THE AREA...  

Moderate to locally fresh NE to E winds prevail N of the ITCZ 
and west of 120W, while gentle to moderate E to SE flow is noted 
south of the ITCZ. A new pulse of northerly swell will build 
seas to 8 ft N of 29.5N between 121W and 130W early Fri.
