Transcript for Isaac Wreaks Havoc Despite Storm Downgrade
We're going to begin with isaac. No longer a hurricane. But still wreaking havoc this morning. Here, we see the storm track. The remnants are coming further north and bringing dangerous rain to the northwest this morning. Take a look at these pictures. New flooding overnight, in alabama, arkansas, mississippi and missouri. Let's get the latest from our extreme weather team, starting with ginger zee in new orleans. Good morning, ginger. Good morning, everyone. To florida, through alabama, parts of mississippi, and now new orleans, my crew and I have had a long week covering isaac. At least seven deaths attributed to that slow-moving storm. And now, it still isn't done with us. Isaac's idle leftovers are pounding the midwest. Overnight, floods in arkansas left 5,000 people without power. Missouri and illinois, bracing for impact. They'll get up to six inches of rain this holiday weekend. 25 bags of sand will help out, hopefully. Reporter: And the aftermath in louisiana, catastrophic. An eerie sight in braithwaite, uprooted tombs lining the area. A horrible scene, leaving folks lucky to be alive. That tree right there fell right behind my r.V. And I was in it. That tree right there would have killed me. Reporter: We hitched a ride through jean lafitte, louisiana. People here swamped by water and emotion. It's horrible to see anything you worked for just gone. Reporter: And on the east side of the mississippi, plaquemines parish is littered with debris, displaced boats and displaced people. I lost my home in oakdale. We rebuilt here. That's strike two. Waiting on strike three. Reporter: Officials at one gulf coast power company says isaac is the fourth-largest storm in terms of power outages, ever. The number overnight, still over 400,000. And although hundreds of thousands will spend the weekend in the dark, some are choosing to see the light. It's not going to run me off. I love it here. Me and I'm sure hundreds and thousands of people feel the same way. The mississippi river, right behind me, opened today for the first time after four days. We're starting to see boats back and forth. I'll have that full forecast in a couple moments. First, we have to get to my other extreme weather team partner this morning. That would be ryan owens, in robert, louisiana. Reporter: Ginger, good morning to you. It is another sleepless night for the 50,000 or so people who live along this river and still cannot come home. The reason, well, it's painfully clear. Look behind me. This is the main road in and out of the town of robert, louisiana. It is swamped and so is the town. All eyes on that dam to the north of us in mississippi. We thought earlier in the week, at least parish officials here in louisiana did, that that was about to breach. At this point, authorities up in mississippi are telling us it is still holding. And the good news right now, the lake levels behind that are slowly starting to drop. But officials here in louisiana, not ready to take any chances. They are telling people they still can't come home. We were there on thursday when they packed up all they could be just 90 minutes of warning. Think about that. They got in their cars and got out after the parish president said that thing was about to breach. But right now, authorities tell us it's still holding. Ryan, many thanks. We have radar and satellite. Got to show you where this thing is. It is now all the way up in parts of missouri, illinois, and dropping heavier rains this morning. Even some thunderstorms there. And there's a tornado threat, which I'll talk about later in the broadcast. Look how much rain we're talking. Up to six inches in that red targeted area. Parts of illinois, st. Louis, back into far northeastern iowa. I'm going to show you what this is going to help, that drought. South of st. Louis, over to indianapolis, that's where isaac is going to be a good boy and we're going to be thankful that it's moving through. But look at the flood concerns still down here. Rivers crest days after you get all of the flooding. So, we're having a lot of flood watches and warnings. Other than that, it's going to be a pretty normal day here in new orleans. Very summer-like, with the afternoon showers and thunderstorms possible. I can tell you this morning, it's really sticky. I'll have more of the nation's forecast coming up. Now, back to bianna. Thank you. Isaac is packing a punch at
