Updated news – Photos: Isaac Flooded New Orleans, Louisiana and Mississippi (August 30, 2012)
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.
