This from Eric Haak:

At 11:30 Wednesday (1/30/19), the Merrillville, Indiana Fire Department had a 3-Alarm fire at the Stanley Steamer Warehouse, 9154 Louisiana St. The building was a 75×300, 1-story, metal clad structure. The fire burned from the north end all the way through to the south. They had two aerials working on the north side of the building but I had no access to that side. The weather was a brutal; -14 degrees with sustained wind gusts of 23 to 30 mph.
