A tornado (search) damaged about 100 houses in Youngstown (search) on Monday as severe storms across the state flooded streets and knocked out power to thousands. A boy drowned after wading into a rain-swollen ditch.

Wind from the tornado was between 75 and 110 mph, meteorologist Jim Kosarik said. The storm, besides damaging homes, ripped the roof off a tire dealership, overturned several rail cars and uprooted trees. No injuries were reported.

About 2 to 3 inches of rain fell in less than two hours in eastern Ohio (search), adding to the 1 to 2 inches that fell overnight.

In Warren, 10-year-old John Keytack was riding bikes with friends when he wandered into a ditch, which had a strong current, authorities said.

The boy was unconscious when firefighters freed his foot from a drain 5 feet under the water. He was declared dead at a local hospital.

In Cecil in northwest Ohio, authorities suspected lightning started an early morning fire that destroyed Immaculate Conception Catholic Church. The white wooden church, organized in 1879, was a town landmark.

About 23,000 homes and businesses were without power in two eastern Ohio counties Monday night, down from about 50,000 earlier in the day, said Ohio utility officials.

The same storm system swirled east and toppled part of the 121-year-old Kinzua Viaduct, a historic railroad bridge in western Pennsylvania that was once the tallest and largest in the world, officials said.

According to state park officials, storms packing winds up to 80 mph caused much of the bridge to collapse, sending most of it crashing into the gorge below.

"Essentially the middle part of the bridge is gone," said Gretchen Leslie, a spokeswoman for the state Department of Conservation and National Resources, which owns the bridge.

Other storms battered Iowa overnight, with the National Weather Service confirming Monday that a tornado sheared the tops off of three houses in Cedar Rapids, Iowa.

Dave and Trudi Kesterson and their three children took shelter in their basement.

"Then we heard water running everywhere. I thought it was pipes that had burst, but it was raining so hard," Dave Kesterson said. He said he realized their roof was gone when he saw water pouring down the stairs.

The storm system also pushed gusting wind and up to 2 inches of rain in parts of Michigan, where about 1,200 of an estimated 10,000 homes that lost power were still without electricity Monday evening.

Nearly 160,000 customers lost power and thousands of Chicago-area commuters were stranded after the storms rumbled through Illinois early Monday. Lightning was blamed for a substation fire that temporarily knocked out service on a commuter rail line.
