This from Eric Haak:

The Harvey Fire Department had a 3rd Alarm in a commercial building Sunday morning (1/19). There was heavy fire on the second floor of the 50 x 75 corner building. Once the main body had been brought under control, there was a ton of overhaul to be done in the frigid temperatures with a lot of hidden fire that needed to be located before being extinguished.
