Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Sat Mar 25 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 0600 UTC surface analysis and satellite imagery through 
0900 UTC.

...INTERTROPICAL CONVERGENCE ZONE... 

ITCZ from 05N89W to 05N95W to 03N101W to 02N124W to 00N131W. 
Scattered moderate convection within 90 nm north of the ITCZ 
between 124W and 130W. 

...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure west of the area will dissipate as a weak cold 
front moves eastward into Baja California Norte and the northern
Gulf of California through Sunday. 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 northwest winds 
over the central and southern Gulf of California today.

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 gap winds in the Gulf of Papagayo 
through early Monday with seas to 7 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 
early Sunday. The swell will decay below 8 ft through Sunday 
west of 120W. Farther south, a mix of NE wind waves and NW swell 
will maintain 8 to 10 seas from 06N to 22N west of 125W through 
Sunday.
