This is from Josh Boyajian:

Today, I headed to the 2-11 area on the near west side for a fire call. The structure was a large 50x100 Greystone building, and the fire appeared to be mostly on the second floor and in the attic. Firefighters were making an interior attack, while Truck 36 was cutting multiple holes in the roof to ventilate the fire. It was a cold and windy morning, and as the wind picked up, the fire seemed to spread more rapidly. The conditions made it a challenging situation for the crews on scene.
