Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2120 UTC Fri Feb 7 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
2100 UTC.

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

A surface trough extends from 05N77W to 03N80W to 06N95W to 
06N110W. The ITCZ extends from 06N110W to 04N117W to beyond 
08N140W. Scattered moderate convection is noted within 60 nm of
the trough between 90W and 98W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Recent scatterometer data showed moderate northerly winds across
the Baja California offshore waters south of Punta Eugenia and
over the southern Gulf of California, with fresh winds noted off
the coast of Cabo Corrientes. Moderate winds were also occurring
across the Gulf of Tehuantepec. Elsewhere, generally gentle winds
prevailed over the remaining waters.

Fresh northerly winds off the coast of Jalisco and over the Gulf
of Tehuantepec will diminish tonight. An approaching cold front 
will produce strong SW winds Sun and Sun night in the northern 
Gulf of California, followed by strengthening winds and building
seas west of Baja California late Sun night through Mon.
Associated NW swell will propagate across the Baja California waters
through mid week while gradually decaying. 

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

Earlier scatterometer data revealed moderate easterly winds over
the Papagayo region. Elsewhere, light to gentle winds prevail 
across the forecast waters, with wave heights less than 8 ft 
across the region.

Fresh to strong winds will pulse across the Papagayo region
tonight through the middle of next week. Fresh winds will
pulse over the Gulf of Panama region through early next week,
with strong winds expected Sun night. 

REMAINDER OF THE AREA...

A surface ridge extends from 30N131W southeastward to near the
Revillagigedo Islands. Recent scatterometer data indicated
moderate to locally fresh trade winds prevailed south of 20N and
north of the ITCZ, west of about 115W. Combined seas in this
region are generally 7-9 ft in this region, based on recent
altimeter data. These trade winds will strengthen slightly west 
of 125W tonight, then diminish later this weekend. 

A frontal system will approach the far NW waters and stall west 
of 140W this weekend. Strong S to SE winds east of the front will
build seas to 8-10 ft north of 20N and west of 135W Sun through
Mon night. Looking ahead, a set of NW swell will build seas in
the waters west of 130W Tue through Wed. Elsewhere, expect 
increasing winds and building seas in NW to N swell for the 
waters north of 20N and east of 130W Sun through Mon as a
weakening cold front moves SE into the region.
