MARSHFIELD, Wis. (WHBL) - Authorities now say almost two dozen homes were damaged, and about 20 farm buildings were destroyed by a tornado and thunderstorms in Clark County on Tuesday night. The storms contributed to the death of 75-year-old William Nickel, a hospice patient at a home in Granton. He died after a power outage caused his oxygen machine to stop running. Two people also suffered minor injuries. The National Weather Service said an E-F-Two tornado was on the ground for over seven miles near Chili. It packed winds of up to 130 miles an hour. Clark County emergency management officials said four homes were destroyed, two others had major damage, and 17 received minor damage. Four barns and 15 farm out-buildings were destroyed – and numerous other farm structures were damaged. The National Weather Service surveyed the area yesterday – and it found that some structures near Neillsville were also damaged. A minor “F-Zero” tornado also touched down in the Shawano County town of Lessor on Tuesday night. The only damage was to trees. Wisconsin Emergency Management says it’s monitoring the situation – and so far, it has had no requests for state assistance.
