Isaac's Louisiana lashing far from over

Posted: Updated:

NEW ORLEANS – It has already been a long day for people in southeast Louisiana, and the director of the U.S. National Hurricane Center says the rain and wind is far from over.         

Rick Knabb says the first half of Hurrican Isaac hasn't moved through the New Orleans area yet.         

The hurricane made landfall Tuesday evening on Louisiana's southeast coast with 80 mph winds. Since then, it has pushed water over a rural levee to flood some homes, knocked out power to more than 500,000 people and flooded beachfront roads in Louisiana and Mississippi.

The National Weather service has issued a tornado warning for the cities of Long Beach and Gulfport, which are west of Biloxi on Mississippi's Gulf Coast.
