Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 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 1800 UTC surface analysis and satellite imagery through 
2145 UTC.

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

The monsoon trough extends from 07N78W to 08N86W to 08N105W to 
09N126W. The ITCZ continues from 09N126W to 07N134W to beyond 
07N140W. Scattered moderate convection is from 03N to 07N E of 
88W, from 07N to 13N W of 120W.  

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Gentle to moderate NW to N flow prevails off the coast of Baja 
California. Moderate winds dominate the offshores of Baja 
California Sur with locally fresh winds extending to the 
offshores Jalisco. Residual long period NW swell along the Baja 
offshores will subside tonight. Fresh NW winds are expected this 
evening across the central and southern Gulf of California, 
possibly increasing to strong tonight. High pressure N of the 
area will move ENE by Monday, allowing winds to decrease to 
gentle to moderate speeds. Elsewhere, light to gentle breezes 
prevail across the waters off southern Mexico. A cold front 
associated with a complex low pressure system will move S into 
the Baja California Norte waters Mon, then weaken over the Baja 
California Sur waters Tue. Large long period NW swell generated 
by this system will impact the Baja offshore waters Mon through 
Wed. High pressure building over the Gulf of Mexico will support 
strong N gap winds over the Gulf of Tehuantepec Mon night 
through Wed.

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

Moderate to fresh NE to E winds will pulse over the Gulf of 
Papagayo region through Thu. Gentle to moderate SW flow is 
expected across the waters adjacent to Costa Rica, Panama, 
Colombia, and Ecuador.

REMAINDER OF THE AREA...

High pres anchored by a 1033 mb near 36N142W supports a broad 
area of fresh to locally strong NE winds from 10N to 25N W of 
113W. Seas in the 8-11 ft range prevail over this region in 
mixed NW swell and NE swell. Otherwise, gentle to moderate winds 
prevail elsewhere. 

Large NW swell will gradually subside through Mon and allow seas
E of 120W to subside below 8 ft by Mon night. The area of fresh 
to strong trade winds will expand west of 125W through Mon as 
high pressure builds north of the area. A strong cold front will 
be ushered S into the northern waters by low pres heading SE 
along the baja Peninsula 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 between 12 and 16 ft N of 
25N.
