Tropical Storm Isaac is heading north after battering the Gulf Coast with heavy wind and rains. More than 730,000 people remain without power in Louisiana and Mississippi after Isaac slowed to a crawl and lashed the area on Wednesday. Sixty percent of residents of New Orleans have gone without power, and some neighborhoods saw flooding, but the city’s rebuilt levees helped prevent a repeat of the mass devastation of Hurricane Katrina seven years ago. Among the areas to see flooding was Plaquemines Parish, where residents braved surging waters.

Stephen Mattison: “I am concerned. I don’t know what it’s going to do, but we’re going to stay here as long as we can.”

Patty Mattison: “I’m looking at the water in the back (of the house). It’s about ready to get into my laundry room. It (the rising water) doesn’t have too much further to go, because it’s — the laundry room is a little bit lower than the house. And I’m hoping that don’t happen.”

Sherry Campbell: “I saw water in my house. We have a computer room. The computers are all underwater. Just a couple of inches, but still a mess.”

New Orleans Mayor Mitch Landrieu said Isaac’s slow pace would result in extra damage to the Gulf Coast.

Mitch Landrieu: “Unfortunately, the storm just won’t seem to leave us. So, you know, some storms move by very quickly and cause a lot of damage shortly; other storms, that seem to be less powerful, stick around for a long time, and the continual pounding can actually cause more damage. And I believe we’re beginning to see the effects of that across all of Louisiana.”
