An EF-3 tornado tore through the Chicago suburb of Naperville, Illinois, Sunday night, damaging over 130 homes and leaving 22 houses uninhabitable, fire officials said.
"It was like a bomb went off with all the debris in the streets," Ryan Puraleski told ABC News.
Eight people were hospitalized following the late-night twister. One person was critically injured but has since been upgraded to fair condition, Naperville Fire Chief Mark Puknaitis said at a news conference Monday.
Some people had to be pulled from their rubble-filled homes, he said.
Everyone is expected to survive, Puknaitis said.
