The headline implies that this is an agricultural center, which is misleading. There are some farming operations in the basin, and a few small towns (which are protected by ring levees.) That anyone is being flooded is tragic. But it is mostly swampland.
Those ring-levee towns are about to get an epic snake, alligator, and rat infestation. The animals will flee to the nearest dry land.
IMO, sleeping on the second floor with a gun would be recommended.
