A Plaquemines Parish vehicle rides through rising floodwater behind the levee as Isaac approaches, which is expected to make landfall in the region as a hurricane this evening in Venice, La.,  the southernmost tip of Louisiana, Tuesday, Aug. 28, 2012. Venice has been under a mandatory evacuation.  Forecasters at the National Hurricane Center warned that Isaac, especially if it strikes at high tide, could cause storm surges of up to 12 feet (3.6 meters) along the coasts of southeast Louisiana and Mississippi and up to 6 feet (1.8 meters) as far away as the Florida Panhandle.
