Warnings signs remain posted at Waimea Bay today as a precautionary measure.

City Emergency Medical Services spokeswoman Shayne Enright said there were no shark sightings today. Because of the frequent sightings in recent days, however, the signs will remain posted until further notice, she said.

Lifeguards have posted warning signs at Waimea Bay for the past several days after sharks were spotted in murky water just offshore.

The pubic is urged to stay out of the water until further notice.

On Monday lifeguards saw aggressive sharks roughly five yards from shore. The sharks were likely feeding on dead animals, Enright said. She could not provide a number of how many sharks were seen, saying the water was too murky. Sharks were seen close to shore again Tuesday, but not today.

On Thursday an aggressive 6- to 8-foot shark was seen feeding on fish about 30 yards offshore at Waimea Bay. Lifeguards kept signs posted Thursday and Friday.
