NEWPORT BEACH, Calif. - The Latest on shark sightings off Southern California (all times local):

5:45 p.m.

The same Orange County beach closed after several large sharks were spotted over the weekend has been closed down again late Monday afternoon. The closure of a one-mile stretch of shoreline at Sunset Beach in the city of Huntington Beach comes just five hours after the beach had been reopened.

Lifeguards at the beach said they saw three sharks estimated to be about 12 feet long on Monday. It wasn't clear whether any of them were the same sharks spotted on Sunday.

The sightings come a week after a swimmer was attacked by a shark about 15 miles to the south at Corona del Mar State Beach.

The woman suffered a large bite, but she is expected to survive. The shark that attacked her was not found.
