A tornado struck Wisconsin on Monday, causing extensive damage and knocking out power to thousands.

The National Weather Service confirmed a tornado in Winnebago County, about 90 miles northwest of Milwaukee.

No injuries have been reported so far, according to meteorologist Holley Kamba.

The entire city of Menasha (population about 18,000) is believed to be without power due to a downed transmission line.
