Tropical Weather Discussion
NWS National Hurricane Center Miami FL
245 UTC Mon Feb 17 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...

A trough axis extends from 05N77W to 01N80W to 02N83W. The ITCZ 
axis begins near 03N84W and continues along 03N110W to 07N130W 
to 07N140W. Scattered moderate convection is from 07N to 17N 
between 121W and 134W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Strong high pressure centered near 36N135W ridges SE to near
Punta Eugenia. A modest pressure gradient supported by a surface
trough along the Gulf of California supports gentle to moderate 
N winds across the offshore waters of Baja California with seas 
in the 4-6 ft range. Moderate to fresh NW winds are across the 
central and southern Gulf of California to near Cabo Corrientes 
and will prevail through Mon morning with seas to 5 ft. Winds off
Baja and across the gulf will be gentle to moderate the 
remainder of the week.

Strong gap winds in the region of Tehuantepec will prevail
through Mon evening and resume again Wed. Winds in the Gulf of
Tehuantepec are expected to increase to near-gale force Wed 
night and reach gale speeds by Fri morning. Otherwise, light to 
gentle winds will continue over the remaining Mexican offshore 
waters. 

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

Strong to near gale force NE to E winds will continue over and 
well downstream of the Papagayo region through Fri. This large 
area of strong winds will generate seas to 8 to 11 ft during the
week. ENE swell generated by this gap wind event will combine 
with swell propagating S from the Tehuantepec region, and merge 
to create high seas across the offshore waters of Guatemala and 
El Salvador through Mon evening. Fresh to strong N winds 
occurring across the Gulf of Panama and extending S to around 03N
will also change little through Fri. Wave heights across these 
waters will remain between 6 and 8 ft.

REMAINDER OF THE AREA...

A vigorous mid to upper-level low continues to support a surface
trough extending from 07N133W to 12N130W. Surface high pressure 
centered N of the forecast waters is creating a strong pressure 
gradient and supporting strong to near-gale force NE to E winds 
from 10N to 20N W of 120W. Altimeter data over that region show 
seas in the 8 to 13 ft range. The low aloft is also supporting 
scattered showers and isolated tstms from 07N to 17N between 
121W and 134W. Winds are expected to gradually diminish to 
fresh by Mon night along with active weather in this region.
However, seas of 8-11 ft in NE swell will gradually subside
through Wed evening. 

A weak cold front will enter the NW forecast waters by Wed
afternoon. Seas of 8-11 ft in NW swell will follow the front and
affect the forecast waters N of 05N W of 125W through Fri.
