Lifeguards posted warning signs at Waimea Bay on Tuesday 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. Shayne Enright of the city Emergency Services Department could not say how many sharks were in the area due to murky water caused by recent heavy rain.

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.
