Rescue crews pulled people out of submerged cars and homes overnight as floods swept the southeastern part of the state.

A mother, father and child were killed when a tree fell on their car during heavy rain and flooding in Tennessee, where submerged roads also led to dramatic rescues of people trapped in their cars, authorities said.

The family of three was killed when saturated ground caused a large tree to fall in the Chattanooga suburb of East Ridge just after midnight, Hamilton County OEM spokesperson Amy Maxwell said. No one else is believed to be missing at this time, officials said.
