Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1353 UTC Thu Mar 23 2017

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
1415 UTC.

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

None.

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
In the Gulf of Tehuantepec...the pressure gradient combined with
nocturnal drainage flow will continue to support a pulse of
fresh to strong northerly winds through late morning and again on
Friday morning. Seas will build to 8-10 ft this morning and to 8
ft Friday morning.

Elsewhere...a weakening cold front moving across northern Baja
California will continue SE and most of the remainder of the
peninsula through this evening before dissipating on late
Friday. High pressure building behind the front will support
fresh to strong W-NW flow across the northern Gulf of California
through late morning, and N-NW winds off the coast Baja
California and the central and southern Gulf of California
through Friday. NW swell of 8-10 ft is following the front as
well off the coast of Baja California...reaching the
Revillagigedo Islands. Winds will diminish across the area as the
gradient relaxes through Saturday...along with swell subsiding
below 8 ft.

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND
WITHIN 750 NM OF ECUADOR...
High pressure will prevail across the NW Caribbean and Gulf of
Mexico allowing for the continuation of fresh to strong gap
winds across the Gulf of Papagayo through early Saturday with
seas to 8 ft. Winds will then pulse to fresh thereafter.

Elsewhere...light to gentle winds and combined seas of 3-5 ft
are expected to continue the next several days...except in the
Gulf of Panama where they will pulse to fresh breeze levels
through the end of this week.

REMAINDER OF THE AREA...
A cold front extending into the offshore waters area from near
the central Baja California coast at 27N114W to 22N120W to
20N130W will continue drifting SE as it dissipates through this
evening. Seas in the 8-10 ft range behind this front will
propagate SE while decaying through the next 24-36 hours.
Another cold front is forecast to reach the NW portion of the
discussion area Friday morning...followed by a new round of NW
swell. A third cold front may arrive by Sunday evening. Farther
south...combined seas in the 8-10 ft range cover the waters
along and north of the ITCZ.
