Massive waves and powerful rip currents are battering shorelines with some beaches forced to close as the labor day weekend approaches. Nick watt shows us the damage caused by two storms.

Is no more, ripped from the cliffside by the waves. It's like watching a friend go down in the water. Reporter: Wednesday was dubbed big Wednesday. L.a. County lifeguards rescued 172 people. Today, they're pulling towers back from the water just in case, cleaning up the beaches and patrolling the waves. Slightly smaller Thursday? Slightly smaller.
