MILWAUKEE (AP) -- The National Weather Service in Milwaukee says at least 16 tornadoes touched down in Wisconsin as storms rolled through the state.
That tally could grow as weather service crews complete damage surveys of the storm that hit the state on Tuesday and Wednesday.
Several tornadoes touched down in Fond du Lac County. Lori Getter is a spokeswoman with Wisconsin Emergency Management. She says one tornado landed in Dodge County and traveled 3 miles (5 kilometers) on the ground, destroying trees.
Another formed along the Calumet-Manitowoc County line and destroyed a barn. No one was hurt.
Gov. Scott Walker's latest stop on his tour of storm damage in Wisconsin is Fond du Lac County.
Walker's office says the governor plans to survey the damage in the county Thursday morning where at least six tornadoes touched down this week. State emergency officials say 20 counties have been affected by flooding over the last 10 days.
Walker on Wednesday declared a statewide emergency, directing state agencies and the Wisconsin National Guard to assist local authorities as needed.
This week's storms also left a trail of damage in Minnesota where torrential rain washed away an entire hillside near Como Falls, a waterfall on Thompson Creek. Local officials say the picturesque waterfall is gone and damage to the park is severe. Without the falls, authorities are concerned about a handful of nearby houses that could be flooded.
