A two-alarm fire ripped through a multi-use building in Milwaukee Sunday night.
Firefighters had to remove metal covers and bars that covered the windows, TMJ4 reported.
The owner of the building advised fire officers there were hoarding conditions in the basement.
Deputy Fire Chief Ron Firnrohr told reporters: "The wind will push the smoke into the building, and then it'll push out. When air pushes into the building, it's more likely to flame up, and you'll see that. But it's mostly the wind. It's usually not something that's inside the building that's doing it, it's wind conditions. Especially now, since we've opened so much up. So we're trying to manage our water towers to be able to get to the pockets of fire that are deep inside the building."
There were no injuries.
