Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2038 UTC Wed Mar 11 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
2030 UTC.

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

Surface trough extends from 07N82W to 02N93W. ITCZ extends from 03N94W
to 04N133W. A surface trough is from 07N134W to 03N135W. ITCZ 
resumes near 03N136W to 03N140W. Scattered showers are from 00N 
to 07N between 92W and 120W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

The stationary front that is crossing Baja California Norte  
will continue weakening tonight and dissipate by late Thu. S to 
SW winds will increase to fresh to strong over the northern 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 1016 mb surface low is centered near 30N123W, with its cold 
front extending S from it to 20N133W. 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 04N to 11N between 94W and 115W 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.
