The mighty Mississippi River is expected to rise to record levels tonight, as it surges south towards Natchez and Vicksburg.
Experts say the river is moving at 1.8 million cubic feet per second through the Mississippi Delta.
This is so fast, it could fill Louisiana's Superdome in just thirty seconds.
Governor Jindal says, when the river's flow reaches 1.5 million cubic feet of water per second at Red River Landing, the U.S. Army Corps of Engineers will open the Morganza Spillway.
This will send a torrent of water down the Atchafalaya, that may flood more than 3 million acres, according to Governor Bobby Jindal.
