Flood waters expected to crest in Memphis later today.
The Mississippi River is expected to crest this evening in Memphis at a near record level of 48 feet.
The city has been fighting the water for weeks.
Emergency teams are making sure everyone is ready.
"I have 150 engineers out looking at flood walls, levees, pump stations and working close with our partners to ensure these structures are performing as designed," says Army Corps of Engineers Col. Vernie Riechling.
At this point they are working, but there's still just too much water to deal with, especially in tributaries that have poured over their banks and into neighborhoods.
"The water will recede about as slow as it crested, and then we have rain later this week so we'll be dealing with this event for some time to come," warns Shelby County EMA Director Bob Nations.
As the water continues to flow to the south, so do concerns.
The Army Corps of Engineers has opened the Bonnet Carrie Spillway just north of New Orleans, hoping to divert some of the flood waters before they reach that city.
