A hospital official confirmed Monday evening that a woman swimming in a wetsuit off the coast of Corona del Mar was attacked by a shark.

“Her injuries appear to be consistent with a shark bite,” said Jeff Corliss, a spokesman with Orange County Global Medical Center. “She is expected to survive.”

The yet unidentified Orange County woman – who is recovering at the Santa Ana hospital – was attacked Sunday afternoon about 150 yards off Corona del Mar State Beach. She was found at 4:15 p.m. by Newport Beach lifeguards on a routine boat patrol of the water when she frantically waved her hands from the water. She was conscious and able to talk to them.

A press conference is scheduled for 10:30 a.m. Tuesday, Corliss said. More details of the shark attack, injuries, and the woman’s condition are expected to be revealed then, he said.

Following the incident Sunday, Newport Beach lifeguards closed off the ocean from Balboa Pier south to Crystal Cove State Park. A Huntington Beach helicopter, an Orange County Sheriff Harbor Patrol boat and Newport Beach lifeguard boats on Monday began monitoring the water early looking for the shark.

Newport Beach Chief lifeguard Rob Williams said boat and helicopter patrols were aware of what to look for and would continue patrols into Monday night.

The helicopter – that last year patrolled Sunset Beach after reports of multiple juvenile great white sharks – was expected to fly beyond the closed off water area and sweep the coastline from Seal Beach to San Clemente, Williams said.

By early evening lifeguards reported no shark sightings. Still, lifeguards will keep the water off Newport Beach from Balboa Pier south to the city limits closed until at least Tuesday morning, said Tara Finnigan, a spokeswoman from city of Newport Beach. Lifeguards at Crystal Cove State Park will make their own assessment, Finnigan said.

Newport Beach lifeguards and police personnel will continue to evacuate anyone who enters the water in this area until a determination is made that all, some or none of area can be reopened, she said.

For Booker Thorpe, it was supposed to be his first day in the ocean Monday.

But as the 3-year-old ran into the shallow waves with his dad, Sam Thorpe, Newport Beach lifeguards quickly hailed them from the water.

Sam Thorpe, 34, of Corona del Mar, said he noticed news crews at the top of the cliffs overlooking the beach but didn’t worry much about them on the dreary cool Memorial Day holiday.

“We just went out into the water,” he said. “We thought no one was in the water because it was overcast. We thought maybe there was a 5 K or some race going on down here.”
