A five-story warehouse building on Chicago's South Side caught fire Tuesday night, in what became the city's largest blaze in seven years, the Chicago Tribune reports. NBC Chicago describes the scene the next morning:
[T]he five-story building was covered in ice from all the water poured onto it in freezing temperatures. Chicago saw dangerously cold 10-degree temperatures overnight after the coldest day in several years with wind chill lows plunging to -10 and -20 degrees.
Here's what Reuters photographer John Gress saw today.
