La Crosse, Wis.- Gov. Scott Walker is in La Crosse to tour the damage caused by Sunday's tornado.

Walker says his heart goes out to everyone affected by the storm and says he's grateful no one was seriously injured. Walker toured damaged neighborhoods by car Monday afternoon.

At least 200 homes and businesses were damaged by the tornado, which was part of the same big storm system that spawned the deadly tornadoes around the Midwest.

National Weather Service meteorologist Glenn Lussky said preliminary assessments from field crews show the powerful storm was in fact a tornado and possibly an EF1.
