Tropical Weather Discussion
NWS National Hurricane Center Miami FL
206 UTC Thu Mar 12 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
0230 UTC.

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

Surface trough extends from 08N85W to 01N98W. ITCZ extends from 
01N100W to 03N135W. A surface trough is from 09N131W to 02N137W.
Scattered showers are from 00N to 10N between 92W and 121W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface trough crosses Baja California Norte from 31N115W to
20N120W. The trough will continue weakening tonight and 
dissipate by Thu. S to SW winds will increase to fresh to strong
over the Gulf of California ahead of the next cold front Thu 
night and Fri. A period of fresh to locally strong NW winds are 
expected tonight over the far southern Gulf of California, 
extending S to Cabo Corrientes. Tranquil conditions should be 
occurring over all of the waters from Fri night through the 
weekend. 

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

The gradient between high pressure over Central America and 
lower pressure over the tropical eastern Pacific continues to 
result in fresh to locally strong NE winds over the Gulf of 
Papagayo. These winds will generally continue through the end of
the week. Peak seas will reach near 9 ft in mixed NE wind waves 
and S swell, slightly subsiding by Thu night through Fri night.

No large swell is anticipated for the Central American and 
equatorial Pacific zones during the next several days.

REMAINDER OF THE AREA...

A 1015 mb surface low is centered near 30N123W, with its cold 
front extending S from it to 20N129W. Fresh northerly winds 
prevail behind the front, and will diminish through tonight. The 
low pressure will drift SE over the next couple of days, while 
weakening.

A larger plume of upper-level moisture moving NE from the ITCZ
toward Baja California is producing scattered showers and 
thunderstorms.

Overall weak trade winds will prevail into the weekend, with seas
in the area falling below 8 ft by early Fri to the W of 115W.

Farther east, a large area of 8-9 ft wave heights persists from 
roughly 06N to 11N between 94W and 114W from a mix of S swell 
and shorter period NE to E swell originating from gap winds in 
the Gulfs of Tehuantepec and Papagayo. This will diminish below 8
ft by Thu.
