Please see Special Features section above for information on a
gale warning in the northern Gulf of California. 
A cold front extends from low pres near 32N116W to 28N116W to
22N121W. Scattered moderate and isolated strong convection is 
ahead of this cold front, impacting the Baja California offshore 
waters as well as the northern and central Gulf of California. 
Aside from the northern Gulf of California, fresh to locally 
strong winds, and rough seas to 9 ft, are affecting the Baja 
California offshores N of Punta Eugenia. Fresh to strong N to NE
gap winds, and seas of 8-9 ft, are over the the Gulf of 
Tehuantepec. Elsewhere, light to gentle winds and moderate seas 
to 6 ft prevail, except slight to moderate over the central and 
southern Gulf of California.
For the forecast, fresh to strong N gap winds, and rough seas to
8 ft, over the Gulf of Tehuantepec will decrease Mon morning. The
front will move across the Gulf of California and east of the 
area by Mon morning. Fresh to locally strong winds and rough seas
ahead of the front over the waters off Baja California Norte 
will decrease by this evening. Fresh to gale force SW winds, and 
rough seas to 9 ft, over the northern Gulf of California ahead of
the front will decrease this evening. Winds will further 
diminish through Mon morning. High pressure will build in the 
wake of the front. The pressure gradient between this area of 
high pressure and low pressure over Mexico will support moderate 
to fresh northerly winds in the Gulf of California as well as 
offshore the Baja California peninsula through midweek. Long 
period NW swell will build seas to 8 to 9 ft N of Cabo San Lazaro
Tue night into Thu. 
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, 
AND WITHIN 750 NM OF ECUADOR...
Fresh to strong NE winds, and seas of 8-9 ft, are over and 
downstream the Gulf of Papagayo to near 90W. Moderate or weaker 
winds and moderate seas in SW swell are elsewhere. 
For the forecast, fresh to strong NE to E gap winds over the 
Gulf of Papagayo region will diminish to moderate or weaker 
speeds by Mon evening. Low pressure may develop SW of Costa Rica 
late Tue and is forecast to bring an increase in winds and seas 
over the waters off Costa Rica and Panama into early Fri morning.
...REMAINDER OF THE AREA...
A cold front extends from low pres near 32N116W to 28N116W to
22N121W. Moderate to fresh winds, and seas of 6-9 ft are N of 
the front. Elsewhere, winds are moderate or weaker with moderate
seas, except rough seas from 02N to 06N between 107W and 112W. 
For the forecast, the front will shift east of the discussion
area tonight, with winds and seas decreasing. Another cold front
is forecast to enter the NW waters on Mon, which will be 
followed by fresh to strong winds and long period NW swell 
resulting in very rough seas to 13 ft over the far NW waters. 
The front will move eastward and dissipate Tue night west of the 
Baja California offshore waters. NW swell generated from the 
frontal system will spread SE, bringing rough seas over much of 
the waters N of 10N and W of 120W by midweek.
