MILWAUKEE — The buzz of chain saws could be heard around Wisconsin Thursday as residents worked to clean up from this week’s damaging storms.

The National Weather Service says at least eight tornadoes touched down in Wisconsin as storms rolled through the state Tuesday into Wednesday.

Weather service meteorologist Mark Gehring says six of those tornadoes were in Fond du Lac County.

Lori Getter, a spokeswoman with Wisconsin Emergency Management, said the seventh tornado landed in Dodge County and traveled 3 miles (5 kilometers) on the ground, destroying trees. The eighth tornado formed along the Calumet-Manitowoc County line and destroyed a barn. There’s been no reports of any injuries, she said.

Gehring said the weather service is still surveying damage and the confirmed number of tornadoes will likely increase.

Gov. Scott Walker planned surveyed damage in Fond du Lac County on Thursday morning. He posted pictures on Twitter showing him walking with U.S. Rep. Glenn Grothman past a downed tree and examining storm-twisted fascia on a house.

Walker declared a statewide emergency on Wednesday, authorizing state agencies and the Wisconsin National Guard to help local governments with recovery efforts.

Despite a day of quieter weather Wednesday, flood warnings remained in effect for the Milwaukee River in Ozaukee County, the Crawfish River at Milford, the Rock River at Waupun, the Wisconsin River at Portage, the Baraboo River in Sauk County and the La Crosse River in La Crosse County.
