Tornadoes and very strong winds peel the roofs from homes in the Deep South and heaped snow and ice on the Midwest.
Golf-ball and baseball-sized hail pelted parts of Georgia and the Carolinas late Thursday and early Friday.
Three people were killed.
Isaac was downgraded to a tropical depression on Thursday and is moving into the central United States.
It left little damage in New Orleans, where stronger barriers were installed after Hurricane Katrina in 2005 but leaving large areas of the region flooded.
A report says that seven tornadoes have spun off from Isaac in Mississippi and Alabama.
A tornado that touched down in Gulfport, Mississippi had caused significant destruction to homes.
Now, there is a potential failure of Lake Tangipahoa Dam in Mississippi’s Percy Quin State Park.
Authorities ordered the immediate evacuation of tens of thousands of residents in nearby communities in Louisiana and Mississippi as a protective measure if the dam burst flooded the areas.
The Category 1 Hurricane Isaac hit New Orleans exactly seven years after New Orleans was hit by Hurricane Katrina on August 29, 2005.
So far the new barriers built to protect the city after the 2005 Katrina disaster has not been breached.
Anyway a levee on the outskirts of New Orleans has been breached on Wednesday.
Emergency management officials in low-lying Plaquemines Parish reported the over topping of an 8-foot (2.4-meter) high levee between the Braithwaite and White Ditch districts southeast of New Orleans.
There are reports of people on their roofs and attics and 12 to 14 foot of water in their homes.
The greatest concern is an expected storm surge of between 6 and 12 feet off the Louisiana and Mississippi coasts, 4 to 8 feet along the Alabama coast and 2 to 4 feet on the Florida Panhandle.
Storm surge is when hurricane winds raise sea levels off the coast, causing flooding on land.
Farther south, water was pushed over a rural levee and flooded some homes.
Beach front roads were under water, and more than a half-million people had lost power in Louisiana.

Hurricane Isaac crashed ashore in southeast Louisiana on Tuesday, bringing high winds and heavy rain.
Nearly 70,000 people in Louisiana were without electricity.
On Tuesday, some parts of Louisiana’s low-lying Plaquemines Parish were already flooded.
The effects of the large, slow moving storm have already been felt along the coast lines of Louisiana, Mississippi and Alabama.
Large storm surge caused flood in Louisiana and winds gusted to 99.7793 kilometers per hour (62 miles per hour) in New Orleans.
On Tuesday morning, engineers closed the new floodgate at Lake Borgne, east of New Orleans, for the first time.
It is largest storm-surge barrier in the world.
Hurricane Isaac is predicted to hit New Orleans almost exactly seven years after Hurricane Katrina hit New Orleans on August 29, 2005 killing more than 1,800 people and causing billions of dollars of damage.
People were urged to leave the low-lying areas in Mississippi, Alabama and Louisiana because the hurricane could flood towns and cities in, with a storm surge of up to 12 feet high!
Before turning into a hurricane, Tropical Storm Issac had already killed at least 23 people in Haiti and the Dominican Republic.
Tropical Storm Debby is moving slowly to the Florida coast on Sunday, June 24.
This brings strong winds and waves that forced the closure of about a quarter of offshore oil and gas production in the Gulf of Mexico.
Several Alabama beaches were closed due to rough surf.
According to an emergency management official, earlier on Sunday, it caused tornadoes that killed a woman, severely injured a child and wrecked homes in central Florida in rural Highlands County.
The National Hurricane Center maintained a storm warning for the Mississippi-Alabama border, extended warnings for Florida’s northwest coast to Englewood, and discontinued warnings for the Louisiana coast.
Residents were warned to expect storm conditions within 36 hours.
This is a disaster.
Powerful storms stretching from the Midwest to the Gulf of Mexico caused powerful tornadoes late Friday.
This is the second powerful tornado outbreak this week.
The powerful tornadoes flattened buildings in several states, badly hit two Indiana towns and killing at least one person in Southern Georgia.
At least 39 people were killed by the Friday disaster.
Missouri, Illinois, Kentucky, Indiana, Tennessee and Kansas were hit by storms and powerful tornadoes from late Tuesday through Wednesday.
On Sunday a powerful storm hit Alabama.
The storm produced a possible tornado that damaged the area.
At least 2 people were killed and about 100 people were injured.
It happened hours after tornadoes struck portions of Arkansas.
The storm cut down trees and power lines and damaged houses.
By Monday, almost 8,000 people across Arkansas were still without power.
A tornado is a big huge wind that is shaped like a torn and brings things away.
If you’re in a car driving and there’s a tornado some where around you, get out of your car.
Search for a drain and lie flat facing down and put your arms above your head.
Do not drive under any fly-over or highway.
On Sunday afternoon, May 22, 2011 a tornado hit Joplin, a southwestern Missouri town killing at least 89 people.
