NWS National Hurricane Center Miami FL
2016 UTC Thu Mar 19 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 1800 UTC surface analysis and satellite imagery through
2200 UTC.

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

A trough extends from 09N84W to 05N90W. The ITCZ continues from 
05N90W to 03N103W to 01N124W. Scattered moderate convection is 
from 03N to 06N between 92W and 98W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A weakening cold front has now stalled from the Sonora/Sinaloa 
border across the southern Gulf of California to SW of Baja 
California near 17N117W. This front will dissipate by Fri 
morning. Remnant NW swell is producing 8 ft seas over offshore 
waters of Baja California. This area of 8 ft swell will move S 
over the next 48 hours.

A weak trough just inland of Mexico's west coast may lead to some
fresh winds off Cabo Corrientes through Sat. Another stronger
trough that will develop over the Bay of Campeche this weekend
will create strong N winds in the Gulf of Tehuantepec from Sat 
to Monday evening. Winds will pulse to near gale Sat and Sun 
nights due to enhanced drainage flow. Seas of 8 to 10 ft will 
accompany these winds.

Gentle to moderate winds and seas to 6 ft in mainly long period
SW swell are expected elsewhere through the weekend and into
early next week.

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

High pressure over the northern Caribbean will maintain fresh to
strong NE to E winds over the Gulf of Papagayo region through
early next week. Winds during this period will be highest at 
nights. Associated seas will build to 8-9 ft occassionally.

Moderate to fresh N-NE winds will pulse in the vicinity of the
Azuero Peninsula through the weekend, with seas up to 7 ft in 
long period SW swell.

Expect gentle to moderate winds to prevail elsewhere across the
offshore waters.

REMAINDER OF THE AREA...

A weakening cold front has stalled this morning and now stretches
from Baja California Sur to near 17N117W. This front will 
dissipate tonight. Moderate to fresh N-NE winds are noted N of 
the ITCZ to around 21N and to the W of this front. Associated 
seas are mainly 7-10 ft across this same area , with 5-8 ft in 
the NW portion of the area. Seas will diminish some through the 
end of the week.

Another cold front will move into the NW waters this evening and
extend from 30N130W to 26N134W to 25N140 Fri evening. An 
associated low pressure will become occluded mainly just north of
the area this weekend, allowing several reinforcing fronts and 
troughs to rotate around it and into the area. Ahead of the first
front, expect a surge of fresh to strong SW winds this evening 
to Fri evening. Then, a surge of strong W to NW winds expected 
Fri evening through Sat evening N of 26N and W of 132W. Seas of 
around 8 to 11 ft will arrive in this area Sat evening.
