BENTON, Ark. -- Storms moving across Arkansas are bringing what a National Weather Service forecaster calls a "two-headed monster." Forecaster John Lewis is talking about flooding and the threat of tornadoes.

Heavy rain led to evacuations in the Searcy County town of Leslie, where there is a threat of mudslides. Parts of U.S. 65 were under water at Leslie and further northwest at St. Joe.

Many roads in southern Lonoke County were flooded, including Arkansas 13 near Carlisle and Arkansas 31 between Blakemore and Coy. Stone County also reported flood damage and Arkansas 263 in Cleburne County was impassable. Part of Arkansas 9 in Izard County was flooded, along with many county roads.

A number of washouts were reported on county roads in Sharp County.

Lewis says storms moving from Texas into Arkansas are setting the stage for possible tornadoes. He says there is a lot of shear in the atmosphere, which primes the sky for tornado development. Supercell thunderstorms are also a possibility.

Flooding remains a concern in eastern Arkansas, where rivers have been swollen for three weeks.
