SHAWANO, Wis. (AP) — Severe storms packing winds estimated at 90 to 100 mph damaged residential property, downed power lines and toppled trees, including one which fatally injured a motorist in Menominee County. Emergency management officials say a woman was killed in Keshena Wednesday night when a tree fell on her vehicle. Authorities say about a dozen homes in the Bonduel area of Shawano (SHAW'-noh) County sustained damage. A lightning strike caused a fire at a nursing home forcing the evacuation of approximately 13 residents. They were taken to a sister facility. The National Weather Service says most of the damage in Shawano County was caused by straight-line winds. More than 20,000 utility customers lost power in the storms. By Thursday, crews had restored service to all but about 1,000 customers.
