Sharks swarm near Palm Beach

A dangerous situation has the beaches in Palm Beach, Florida closed to swimming.

From their vantage point, beach goers can't really see what's lurking just off shore. But if you take a look from the air you can see hundreds of sharks.

The spinner sharks are just beyond the surf, feeding on migrating fish.

Cooler temperatures this winter have pushed the sharks closer to shore than usual.

Red flag warnings are posted keeping visitors grounded for now.
