Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Mon Mar 27 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 1800 UTC surface analysis and satellite imagery through
2100 UTC.

...INTERTROPICAL CONVERGENCE ZONE... 

The ITCZ axis is south of the Equator.

...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure of 1031 mb centered north of the area near 35N135W
extends a ridge southeast to near the Revillagigedo Islands. The
pressure gradient between the ridge and lower pressures over the
Gulf of California is supporting fresh to strong northwest winds
west of Baja California Norte and moderate to fresh winds west 
of Baja California Sur. Seas west of the Baja California 
peninsula are in the 7-9 ft range. Gale force winds north of the
area off the coast of southern California will generate a set of
large, long period northwesterly swell. This swell event will 
propagate into the waters off Baja California Norte tonight, and 
peak near 13 ft Tuesday.

Light winds with seas 2 ft or less prevails over the Gulf of 
California. As the aforementioned high pressure builds eastward,
winds will increase to 20-25 kt in the northern Gulf of 
California by early Tuesday morning. The fresh to strong winds 
will spread south across the central Gulf of California waters 
later in the day before diminishing below 25 kt by midweek. 
Elsewhere, winds will generally be light to gentle with seas in 
the 4-6 ft range through the the week. 

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

Winds will pulse to moderate to fresh in the Gulf of Panama the 
next several nights. Elsewhere, light to gentle winds and seas of
3- 5 ft are expected to prevail over the forecast waters the 
next several days.

REMAINDER OF THE AREA...

High pressure prevails over the northern waters. The pressure
gradient between this area of high pressure and the equatorial 
trough is supporting fresh to strong trades over the trade wind 
belt. Seas over this area are in the 8-10 ft range in a mix of 
long period NW swell and NE wind waves. This area of trades will 
persist through midweek.
