The coldest temperatures to hit Johnson County in two years had firefighters responding to three fires caused by residents trying to keep warm.
The fires — one in Franklin, a second west of Franklin and a third near Bargersville, along with two in Indianapolis — have officials warning residents to make sure fireplaces work properly and to keep flammable items away from space heaters.
One of the local fires was caused when gasoline fumes were ignited by a space heater in a garage. The other two were caused by flames that spread from a home fireplace.
The fires caused three families to flee their homes during the coldest weather in two years. The temperature hit a low of 4 degrees Tuesday morning, with wind chills as low as 10 degrees below zero — the coldest the area has had since Feb. 10, 2011, when the low was 1 degree below zero.
