Emergency crews are trying to assess the damage. The Mehlville Fire Protection District said there are six collapsed homes that are west of Watson Road, near Lindbergh. Cars are overturned and many more homes have extensive damage. Trees and branches littered the streets making it very difficult for vehicles to get around.
Thirty homes had to be temporarily evacuated because of a gas leak.
People who are without a place to stay tonight can go to the Community Center. The Red Cross is also in the area to help the families.
Major Jim Curl from the Salvation Army said its teams are in the area to hand out vouchers for hotel rooms to storm damage victims. Teams are also passing out snacks, food, water and drinks to emergency crews.
Power is out in the area and crews hope to get it restored as soon as possible since temperatures are expected to drop dramatically tonight.
