The National Weather Service says a tornado packing peak winds of 90 mph traveled nearly 7 miles through the northern Illinois city of Ottawa.
It says the tornado was one of at least four that touched down in northern and central Illinois Wednesday night as powerful storms moved across the state.
The weather service said the Ottawa twister was an EF-1 in strength and carved a 100-yard path over four minutes. No one was hurt.
It said earlier an EF-2 tornado with estimated top wind speeds of 115 to 125 mph cut a path more than 11 miles long through the nearby city of Pontiac. It was about four football fields wide. That tornado injured four people.

A northwestern Indiana town buffeted by high winds has declared a state of emergency.
Brookston made the declaration Thursday morning after the entire town lost power. WLFI TV says two state highways in the town are blocked by storm debris. Authorities are warning people to avoid the area.
Town Marshal Troy Yeoman says storm sirens didn't sound because of the power outage. The National Weather Service says a 100 mph wind gust was recorded in the nearby town of Battle Ground.
Brookston resident Steve Hall tells WLFI-TV "the wind was so ferocious" that people couldn't stand in it. He says the wind took a healthy, young tulip poplar tree and "just twisted it and laid it over like a pretzel."
Red Cross volunteers say nearly 50 families are at an emergency shelter.

One homeowner says he huddled in a basement with his wife, two children and seven neighbors when a storm that produced a tornado moved into the northern Illinois village of Seneca.
