Lifeguards have posted warning signs at Waimea Bay today after sharks were spotted just offshore for the second day in a row.

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

On Monday lifeguards saw aggressive sharks roughly 5 yards from shore in water murky due to recent heavy rain. The sharks were likely feeding on dead animals, city Emergency Services Department spokeswoman Shayne Enright said. She could not provide a number of how many sharks were seen, saying the water was too murky.

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.
