Daytona Beach, FL - 13 Oct 2006: 'Purple Flag' Shark Warning Issued

Purple flags, indicating that dangerous marine life has been spotted in the water, were flying along beaches in Daytona Beach on Friday, near where a surfer was bitten in the leg earlier this week.

"Hundreds of bait fish were seen in churning up the water and, according to lifeguards, where there are small fish there are also sharks sure to be in the same vicinity," Local 6's Tarik Minor said, prompting lifeguards to warn swimmers not to go in water above their waist and to stay close to shore.

The conditions are expected to persist through the weekend.
