“These are very difficult to see when driving. Do not approach wires down, dial 911,” the sheriff’s office said.

Alex Vucha, a spokesperson for several fire departments in McHenry County, said there have been hundreds of weather-related calls that crews responded to in the past day.

Vucha urges residents who are experiencing a power outage to not run generators inside their homes.

Gas-powered generators create deadly carbon monoxide which can quickly fill a home, Vucha said.
