ASHLAND, Miss. — The death toll from weekend thunderstorms that hit Tennessee, Mississippi and Kentucky has risen to 19.

The deaths of two additional people in Mississippi are being called weather-related traffic deaths.

Officials in Nashville are preparing for more deaths and for the Cumberland River, which winds through the Music City, to crest more than 11 feet, putting portions of downtown in danger of the kind of damage experienced by thousands of residents whose homes were swamped by flash floods.

At least 11 are dead in Tennessee, six in Mississippi and two in Kentucky.
