MIAMI (AP) - Celia has been upgraded to hurricane status as it howls toward open seas, away from Mexico's Pacific coast.
      
The U.S. National Hurricane Center in Miami says the storm is expected to gradually strengthen. It already has maximum sustained winds of about 75 mph with higher gusts. The storm is listed as a Category 1 hurricane.
      
Celia is centered about 365 miles south of Acapulco this afternoon, and is moving westward at about 7 mph.
      
That course will take toward the open Pacific and forecasters say it poses no immediate threat to land.
      
Elsewhere, Blas has weakened and was downgraded to a Tropical Depression. The storm is far from land, with its maximum winds dropping to 35 mph, down from about 60 mph last night.

That storm is centered 470 miles southwest of the southern tip of Mexico's Baja California peninsula.
