AETNA, Tenn. (AP) — Authorities say a dozen residents in a central Tennessee county have been evacuated from their homes because of flooding caused by heavy rain while tornado watches and warnings have been issued for northern Alabama.

Janet Kelley of the Hickman County Emergency Management Agency in Tennessee says flat-bottomed rescue boats were used Saturday morning to retrieve residents in Aetna, located about 80 miles southwest of Nashville.

Kelley says the flooding later receded and many of the residents were able to return to their homes. She says some county bridges remained closed because of the weather on Saturday.

Meanwhile, the National Weather Service has issued a tornado warning for Fayette and Lamar counties in western Alabama.
