Authorities still hadn't found the shark that bit a woman on Sunday, Newport Beach Chief Lifeguard Rob Williams told KPCC on Tuesday afternoon. All of the beach has been reopened except for a one-mile stretch at Corona del Mar State Beach.
Williams said that, unless the shark is spotted Tuesday night, the beaches will be fully reopened Wednesday morning.
Waters from Balboa Pier South and Crystal Cove State Beach remained closed to swimmers Tuesday morning as authorities search for signs of a shark that likely attacked a woman Sunday.
While no one could enter the water in these areas, the beach remained open.
The unidentified woman was injured while swimming about 150 yards off the shore of Corona del Mar, according to a statement from the City of Newport Beach. Hospital officials confirmed Tuesday that the wounds on the woman's torso and arm were consistent with a shark bite.
Authorities had treated the incident as a shark attack from the beginning based on her injuries, even though they said they could not automatically confirm it was a shark.
No shark sightings were reported before or after the incident. Authorities have searched for the shark by boat and helicopter.
