Thunderstorms that hit Ohio on Monday brought flooding, tornado warnings and lightning that apparently struck a 911 center in northwest Ohio.

The 911 center in Defiance County lost use of the equipment that automatically locates where calls are originating. No problems were reported due to the loss of the equipment.

Low-lying roads throughout northwest Ohio were closed because of flooding, including state routes in Defiance, Fulton and Seneca counties.

Toledo officials said some areas received as much as 4 to 5 inches of rain since Saturday.

In Columbus, the stormy weather forced postponement of the open football practice and autograph session that Ohio State had scheduled for Monday at Ohio Stadium. The practice, which drew an estimated 28,000 fans a year ago at another field on campus, was rescheduled for Thursday night.

In Crawford, Morrow and Richland counties in north-central Ohio on Monday afternoon, the National Weather Service issued tornado warnings, but they expired without any serious problems reported.

The heavy rainfall in Barberton, in northeast Ohio's Summit County, caused Wolf Creek, connected to the Tuscarawas River, to overflow its banks, flooding streets and buildings.

The ground floor of Heritage Apartments, which police described as a housing complex for senior citizens, was flooded, and about 70 residents were evacuated.

In all, about 200 people in the Akron suburb were evacuated due to high water, and most went to stay with friends or relatives, Barberton police Chief Mike Kallai said. No injuries were reported.
