UPDATE: Rescue crews started around 8:00 am Saturday assisting people.

By lunchtime, 20 people had been helped out of their homes by truck or boat.

Most of those residents live along Highway 111 near the Sequatchie River, which was a foot above flood stage this afternoon.

Rescue crews have opened an emergency shelter at the Sequatchie County Rescue Squad located on Rankin Avenue. 

The Red Cross is set up there to help.

While evacuations are not mandatory, officials urge anyone who lives in a flood-prone area to evacuate on their own and make use of the shelter.

Lt. Christopher Walker with the Dunlap Fire Department expects about 100 people to take advantage of the shelter tonight.

There have not been any injuries reported.

The Dunlap Police Department did say a horse became stuck in fencing in a flooded field. It was able to free itself.
