WAUKESHA COUNTY, Wis. (CBS 58) -- A big clean up is underway in Waukesha today after a powerful storm ripped through the area on Thursday evening, causing a lot of damage including at Carroll University.

Education Hall is closed indefinitely because a majority of the roof blew off.

The physical therapy building is also closed due to damage it sustained.

The rest of the campus reopened Friday morning.

The storm that ripped through Waukesha Thursday around 5:00 p.m. ripped out massive trees, turned over a semi-tractor trailer, collapsed the cinder block wall of a building, downed power lines and blew off several roofs.

Sue Pierman of Carroll University is still warning everyone to be careful when walking or driving through the area.

“It was stunning when I drove in last night the large trees that were uprooted, things like that even coming into Waukesha apart from the Carroll campus. We do want to warn people to still stay away and be mindful of debris because there’s nails and boards and things like that and we don’t want people to get injured," spokeswoman Sue Pierman said.

Pierman says they don’t have a timeline of when the physical therapy building and Education Hall will reopen.
