The cold snap is draining fuel supplies and sending prices higher for customers..
Officials with Amerigas, a propane supplier that serves Berks County, said supplies are tight right now. The company said it's rationing propane in the Reading area and trying to make sure there's enough to go around.
Amerigas said it's running at full force in the Midwest and much of the Northeast.
The company said wholesale propane prices are up 60 percent compared to a year ago.
