In rural Livingston County, a number of homes are uninhabitable and residents are displaced, Sheriff Tony Childress said.



"We have quite a bit of destruction," he said, noting there also was damage to metal sheds and metal grain bins.



Within Pontiac city limits, a mobile home park was struck first and storm continued down Ray Street.



Most of the damage there was caused by downed trees and power lines, he said. During a news conference Thursday morning, a ComEd spokesman said about 99 percent of power had been restored.



Crews were still working in the area of Ray Street removing trees in order to access the remaining power lines.



Russell said about 500 feet to the north of the tornado's path, there was no damage. He said in his home, which is on the north side of Pontiac, the lights did not even flicker.



Pontiac police Chief Jim Woolford credited the fire department for sounding the sirens, which gave people about a 15-minute lead time.



He said the area is in "pretty decent shape" considering the strength of the storm.
