Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Sun Dec 29 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 0000 UTC surface analysis and satellite imagery through 
0330 UTC.

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

The monsoon trough extends from 07N78W to 07N100W to 08N121W. 
The ITCZ continues from 08N122W to 08N130W to 07N140W. Scattered 
moderate convection is from 06N to 09N between 80W and 96W, from 
04N to 13N between 97W and 110W, and from 02N to 09N W of 135W. 
A surface trough extends from 09N119W to 14N115W and supports 
scattered moderate convection with isolated tstms from 10N to 
23N between 104W and 116W.  

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Gentle to moderate NW to N flow prevails off the coast of Baja 
California in the wake of a former cold front that dissipated 
near Cabo San Lucas on Sat morning. Moderate winds dominate the 
offshores of Baja California Sur with locally fresh winds 
extending to the offshores Jalisco. Long period NW swell 
associated with the former front will continue to propagate SE 
across the region through Sun, then subside Sun night. Moderate 
NW winds are expected over the central and southern Gulf of 
California tonight, increasing to fresh by Sun morning, and to 
fresh to strong during the evening hours. High pressure N of the 
area will move east-northeast by Monday, thus allowing the winds 
to decrease to gentle to moderate speeds. Elsewhere, light to 
gentle breezes prevail across the waters off southern Mexico.  

A cold front will move southward into the Baja California Norte 
waters Mon, then weaken over the Baja California Sur waters on 
Tue. Large long period NW swell will impact the Baja offshore 
waters Mon through Wed. High pressure building over the Gulf of 
Mexico early next week will support strong northerly gap winds 
in the Gulf of Tehuantepec early Tue through Wed.

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

Fresh to strong NE to E winds will pulse in the Gulf of Papagayo 
region through the middle of the week while gentle to moderate 
SW flow is expected across the southern waters.

REMAINDER OF THE AREA...

A broad area of fresh to locally strong NE winds persists 
between a ridge dominating the waters N of 15N and the monsoon 
trough/ITCZ. Seas in the 8-9 ft range continue over this region 
in mixed NW swell and NE wind waves. Elsewhere, generally gentle 
to moderate winds prevail across the Pacific high seas. 

Large NW swell associated with a former cold front that 
dissipated on Saturday will gradually subside through Mon. Fresh 
to strong trade winds will develop west of 125W Sun through Mon 
as high pressure builds north of the area. A strong cold front 
will move southward into the northern waters Mon and Tue. Large 
long period NW swell will propagate SE across the forecast 
waters through the middle of next week, with seas building to 12-
16 ft N of 25N.
