ORANGE BEACH, Ala. (AP) -- Some Alabama beaches are closed because of a swarm of sharks swimming just offshore.
The city of Orange Beach is flying double red flags to let swimmers know to stay out of the water around Alabama Point at Perdido Pass.
Aerial video shows large numbers of sharks swimming in shallow waters, and dorsal fins are sometimes exposed.
No attacks have been reported.
Beach safety supervisor Melvin Shepard says the beach closings began over the weekend, and fire officials say it continues Monday.
Shepard says anyone entering the water can be fined. While most people are staying out of the surf, a few are still venturing into the Gulf.
Shepard says the shark swarm may be linked to a large number of fish carcasses in the water during red snapper season.
