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.
Isaac pushed water over a rural levee to flood some homes, knocked out power and immersed beach-front roads in Louisiana and Mississippi early Wednesday as it began a drenching slog inland from the Gulf of Mexico with a newly fortified New Orleans in its path.
Wind gusts of more than 60 miles per hour and sheets of rain pelted New Orleans, where people braced themselves for the storm behind levees that were strengthened after the much stronger Hurricane Katrina hit seven years ago to the day.
Isaac's dangerous storm surges and flooding threats from heavy rain were expected to last all day and into the night as it crawls over Louisiana, the U.S. National Hurricane Center in Miami warned.
