Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2148 UTC Tue Feb 18 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
2130 UTC.

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

A surface trough extends from 00N80W to 04N90W. The ITCZ begins 
near 04N90W and continues to 05N120W to 06N133W. Scattered 
moderate convection is from 03N to 09N between 110W and 120W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A high pressure ridge extends SE from the NE Pacific to just SE 
of the Revillagigedo Islands. This ridge will generally remain 
in place until a stronger reinforcing ridge builds in through the
week, leading to fresh NNW winds and building seas for regional 
waters N of Jalisco. Locally strong winds are possible off Cabo 
Corrientes this weekend.

Fresh to strong N gap winds will continue pulsing in the 
Tehuantepec region through Thu. These winds will increase to 
gale force by Fri through early Sun morning. Elsewhere S of 
Jalisco, generally gentle winds will prevail.

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

Fresh to strong NE to E gap winds will prevail across the 
Papagayo region through the week. These offshore winds will 
prevail as far N as the Gulf of Fonseca. Seas of 8 to 10 feet 
will also persist. In the Gulf of Panama and S to the equator, 
fresh N winds will pulse to strong each night into the weekend. 
Aside from the two aforementioned areas, generally light winds 
will prevail.

REMAINDER OF THE AREA...

A mid-level low pressure over the western waters near 20N134W and
its associated surface trough along 134W from 05N to 15N will
move W of the area by Wed. The pressure gradient in and near it
will result in fresh trades continuing through the week, with
some locally strong winds possible toward the end of the week.
Seas of 8 to 10 ft will also prevail.

A weakening cold front will move into the far NW waters Wed, 
then gradually move toward 125W to the N of 23N into Fri. Behind
the front, expect fresh NW winds. Ahead of the front, trade 
winds will increase to strong by Fri and Sat. NW swell combined 
with swell generated from the trades will lead to a broad area of
8 to 12 ft swell N of the ITCZ and W of 125W for the end of the 
week, into the weekend.
