NEW ORLEANS (AP) - The director of the U.S. National Hurricane Center says Hurricane Isaac could keep its strength through the day as it lashes southeast Louisiana with rain and wind.
Rick Knabb says the storm's main area of circulation is over watery marshlands Wednesday and the New Orleans area may see another day of storm conditions because the first half of the storm hasn't moved through the 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 thousands and has immersed beach-front roads in Louisiana and Mississippi.
A tornado warning has been issued in southern Mississippi as Hurricane Isaac hits Louisiana and Mississippi with high winds and drenching rains.
The National Weather Service says the tornado warning area Wednesday includes the cities of Long Beach and Gulfport, which are west of Biloxi on Mississippi's Gulf Coast.
The warning comes as Category 1 Isaac moves inland in Louisiana, bringing flooding and power outages after making landfall Tuesday evening.
