NWS National Hurricane Center Miami FL
221 UTC Fri Mar 20 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 0000 UTC surface analysis and satellite imagery through
0300 UTC.

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

A trough extends from 09N84W to 03N102W. The ITCZ continues from
03N102W to 03N123W. Isolated moderate convection is from 03N to 
06N between 92W and 102W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface trough is SW of the southern tip of Baja California
from 21N112W to 11N125W. 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 evening and
Sat night due to enhanced drainage flow. Seas to 8 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 
night. Associated seas will then build to 8 ft.

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...
Moderate to fresh N-NE winds are noted N of the ITCZ to around 
21N and to the W of 115W. Associated seas are mainly 8-9 ft 
across this same area. Seas will diminish some through the end 
of the week.

A cold front is over the NW waters this evening and will extend 
from 30N129W to 26N132W to 24N140 Fri evening. An associated low
pressure will become occluded mainly just north of the area near
31N134W Sat evening. Winds within 300 nm of the SW quadrant will
be 25 to 30 kt. Seas will be 12 to 16 ft.
