Waves and currents whipped up by Tropical Storm Bill are creating dangerous conditions on Alabama's beaches. Rescuers have had to assist at least three dozen people in the surf since Friday. 20 of those rescues occurred Tuesday on Orange Beach and Gulf Shores. At least two people had to be taken to hospitals. The main problem is rip currents, which can pull swimmers out to sea. They're difficult to detect, and many people are in the water because it's so hot. Orange Beach safety director Melvin Shepard says people are getting too far out in the surf. The National Weather Service says there's still a moderate risk of rip currents even though the tropical storm has moved ashore.
