Devastating thunderstorms in Tennessee, Kentucky and Mississippi this weekend triggered flooding that left at least 19 people dead and thousands of homes damaged.

The torrential rains are expected to end Monday, but resident will still have to face the painful task of cleaning up.

All Eyes on the Cumberland 

Scores of highways are closed and all eyes are now on the Cumberland River, which winds through Kentucky and Tennessee. The river is expected to crest at its highest level since the early 1960s.

The storms have flooded the Nashville, Tenn. area. A building which once belonged to the Lighthouse Christian school has floated away. Authorities said the water rose so high and with so much power that little could be done to keep the building anchored.

Gov. Phil Bredesen, R-Tenn., has called the state's Army National Guard in to help.

"This is going to go on for a while," Bredesen said. "It's going to take a while for the water to recede and us to get down into this. It's going to take several days for this to get back to anything near normal."

In Kentucky, flooding has forced some to evacuate their homes. It is also washing out roads and threatening bridges.
