Tropical Storm Lee has been downgraded to a tropical depression but the slow-moving storm still poses a flooding threat to inland areas as it makes its way toward the Southeast.
"Just because it's been slow it does not mean it's over," New Orleans Mayor Mitch Landrieu said Sunday.
Lee has already left a major impact on residents along the Gulf of Mexico and beyond. It brought bands of heavy rain and strong winds that pounded parts of Louisiana and Mississippi.
Many spent the holiday weekend shoveling and bagging sand. Flooding swamped many who live in low lying areas.
"This is a subdivision. Look here now, it's all flooded. You got people walking in it, boats and everything," Jesse Wheeler with St. Tammany Parish said.
"It's just overwhelming, a lot of water," flooding victim Kendall Fisher said.
The storm dumped more than a foot of rain in New Orleans.
Six years ago, Hurricane Katrina swamped New Orleans when the levees failed. This time they were prepared.
"We are expecting 15 to 20 inches of rain in the New Orleans region as a result of the tropical storm," Landrieu said.
"As all of us who have been through this know, it is not how much we get but how much we get in a short period of time," he added.
At least 10 tornados touched down across the region, including one in Biloxi, Miss., that nearly killed one woman.
Mississippi resident Mary Lancaster watched from her car as her mobile home was flipped upside down.
"It was unbelievable it was just like nothing I've been through before it was terrible," Lancaster said.
Parts of Lillian, Ala., looked like a war zone after a tornado roared through the area.
"I thought we were dead," one tornado survivor said. "We couldn't breathe. I thought we were dead."
"Came like a freight train. It was real fast, and then it was gone," another storm survivor said.
Meanwhile, President Obama visited residents of Wayne and Paterson counties in New Jersey to see firsthand the devastation caused by Hurricane Irene.
The area was hit hard by flooding. The president promised federal assistance not only for New Jersey but also other areas of the East Coast affected by the storm.
