Waveland public works employee Darryl Antoine looks over his cousin's house near the beach in Waveland, Miss., as Isaac's rain and winds flood the street Wednesday, Aug. 29, 2012, the seventh anniversary of Hurricane Katrina hitting the Gulf Coast. Antoine had been making his rounds of checking the city's water wells when he made a quick stop to make sure the house was secure. (AP Photo/Rogelio V. Solis)
