A 51-year-old woman was in serious condition Wednesday after an apparent shark attack at a popular Hawaii surfing beach.

Lifeguards pulled the woman out of the water. She appeared to be bitten in her arm and shoulder. An expert is expected to examine her wounds to confirm that it was in fact a shark bite.

The Honolulu Emergency Services Department said lifeguards paddled out on rescue boards and brought the woman to shore. Surfers in the water helped. According to the Honolulu Star Advertiser, the woman was about 300 yards from shore at Makaha Beach.

Officials said she frequently visits the Oahu beach regularly. No information was available on the type of shark.

Lifeguards have posted shark warning signs and cleared the water. Officials will reassess Thursday morning whether to reopen the beach.
