Tropical Weather Discussion

2117 UTC Fri Mar 24 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...
There is no ITCZ north of the equator. No significant convection.

...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure west of the area will shift farther westward as a
weak cold front moves southward into Baja California Norte
through Saturday, then shift east across the northern Gulf of
California through Saturday night. Northwest to north winds will
increase off Baja California Norte starting tonight between
lingering lower pressure along a trough over the Gulf of
California and high pressure centered farther west. The area of
strong northwest to north winds will increase in coverage to
within 250 nm off the coast and reach as far south as Cabo San
Lazaro Sunday through Monday night. Northwest swell to 8 ft off
Baja California Sur will decay below 8 ft through tonight. Seas
will build again off Baja California Sunday through Monday as the
winds increase. The leading edge of 8 ft seas will reach the
Revillagigedo Islands by mid week as northwest swell to 12 ft 
reaches Guadalupe Island. Meanwhile expect fresh to strong 
northwest winds over the central and southern Gulf of California 
tonight into early Saturday, but with gentle to moderate breezes
and slight seas will follow through early next week.

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

High pressure prevailing across the northwest Caribbean and Gulf
of Mexico will support fresh to strong gap winds across the Gulf
of Papagayo through early Sunday with seas to 8 ft. Nocturnal 
winds will pulse to a fresh breeze thereafter. Elsewhere, light 
to gentle winds and combined seas of 3-5 ft are expected the next
several days except in the Gulf of Panama, where they will pulse
to a fresh breeze through the weekend.

REMAINDER OF THE AREA...

Long period northwest swell of 8 to 10 ft will follow a cold
front moving eastward across the waters north of 25N through late
Saturday. The swell will decay below 8 ft through Sunday west of
120W. Farther south, a mix of trade wind waves and primarily
northwest swell will maintain 8 to 10 seas from 06N to 22N west 
of 125W through Sunday.
