Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1410 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 1200 UTC surface analysis and satellite imagery through
1400 UTC.

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

A surface trough extends from 04N77W to 04N90W. The ITCZ begins
near 04N90W and continues to 05N120W to 06N136W. Scattered
moderate to isolated strong convection is from 04N to 09N between
110W and 124W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

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

Strong N gap winds will develop in the Tehuantepec region Wed.
These winds will continue through Thu night, then increase to
gales Fri through 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... 

Strong NE to E gap winds will prevail across the Papagayo region
into the weekend, with near gale force wind possible Wed night.
These offshore winds will prevail as far N as the Gulf of
Fonseca. Seas of 7 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.
