Severe storms that hit Arkansas and Missouri push towards the southeast.
There may be as many as three dozen spots where waters of the black river are pouring over the levee in Poplar Bluff, Missouri.
That's why police ordered more evacuations.
Over a foot of rain has fallen since Friday in parts of Missouri.
The Mississippi and Ohio rivers are rising so fast, the 28-hundred residents of Cairo, Illinois have been asked to leave voluntarily.
In Kentucky, people living below an earthen dam in Henry County have already left.
There's evidence the dam there is eroding and might break.
While, in Arkansas, cleanup continues after a terrifying night of tornados, one of which killed four in the town of Vilonia.
Arkansas Governor Mike Beebe toured the damage Tuesday after declaring a state of emergency Monday.
"We had the warning signals that were going off so we got everybody into the safe room…” said Natasha Rowe who, with her family, survived but just barely.
"Honestly we just held on to each other and said we loved each other and that was about it…" said Rowe.
Others just barely had enough time to make it to the basement.
But it's more rain falling and feeding into rising rivers in the Midwest and Midsouth and that's the concern going forward.
