Tropical Weather Discussion
NWS National Hurricane Center Miami FL
106 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 0000 UTC surface analysis and satellite imagery through
0100 UTC.

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

A trough extends from 09N84W to 05N87W to 05N93W. The ITCZ 
extends from 05N94W to 02N106W to 04N122W. Scattered moderate 
convection is from 0N to 07N between 113W and 126W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

The pressure gradient between a cold front extending across Baja
California Sur to 25N112W to 20N116W to 15N120W, and a surface 
ridge across the northern Pacific forecast waters is supporting 
strong to near gale force NW winds over the offshores of the 
Baja California Peninsula N of 26N. Seas to 13 ft are currently
in that region. The front will dissipate tonight near Cabo San
Lucas and winds will diminish to moderate with seas gradually
subsiding below 8 ft through Thu morning. 

Fresh to strong southwest winds are over the northern Gulf of
California N of 27N associated with the aforementioned cold 
front. These conditions will prevail through early Thu as this
portion of the front moves east to north-central Mexico. 

A surface trough developing over the Bay of Campeche over the
weekend will induce northerly winds in the Gulf of Tehuantepec 
reaching near gale force at night on Sat. Strong winds are
expected to begin on Sat morning and the gap event is forecast to
end by Sun afternoon. Seas are expected to build to 9 ft during 
the peak winds. 

Gentle to moderate winds and seas to 6 ft in southwest swell are
expected elsewhere through the weekend.

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 into the
start of next week. Winds during this period will be highest at 
night, reaching near gale force and with seas building to 9 ft.

Moderate to fresh north winds will continue south of the Gulf of 
Panama into Fri with seas to 7 ft in long period southwest swell.

REMAINDER OF THE AREA...

A cold front extends across Baja California Sur to 25N112W to 
20N116W to 15N120W. Moderate to fresh northwest winds are behind
the front between 118W and 130W with seas to 11 ft in NW swell. The
front will dissipate tonight near Cabo San Lucas, however seas 
over the region will gradually subside to below 8 ft by Thu 
morning.

Surface ridging across the northern waters is supporting fresh 
trades west of 120W tonight. Another cold front will push into 
the NW waters Thu night, and extend from 30N130W to 24N140W by 
Fri evening. The associated low will become occluded this 
weekend, and the occluded low pressure system will introduce 
large long period NW swell into the NW waters on Sun, along with 
the potential for strong winds.
