.SYNOPSIS...Moderate southeast winds will pulse over the 
northern Gulf of California, reaching moderate to fresh speeds 
Sun morning as a low pressure develops just north of the area. 
Moderate to locally fresh southeast winds will then prevail 
through Tue night as the low remains stationary. Pulsing fresh to
strong north gap winds will continue in the Gulf of Tehuantepec 
through Sun night as a surface trough is expected to move from 
the Yucatan Peninsula to Veracruz the next several days. 
Afterward, high pressure over the Gulf of America will shift 
eastward, and winds in Tehuantepec will diminish to moderate to 
fresh speeds through Tue night. Rough seas are forecast to 
develop in Tehuantepec Fri night through late Sat. Elsewhere, 
moderate or weaker winds and moderate seas will prevail.
