Severe Weather Rakes Midwest; 5 Dead

(CNN) -- Five people were killed in Ohio as severe thunderstorms and tornadoes raked the Midwest on Saturday and early Sunday, authorities said.

The deaths came in Wood County, Ohio, when a tornado touched down there overnight, state Emergency Management Agency spokeswoman Kelli Blackwell told CNN. Wood County is about 30 miles south of Toledo.

A 4-year-old child was among the deaths in Millbury, Ohio, Blackwell said. A man was also found dead in the street in Millbury, and two adults died in a van in Lake Township, about five miles from Millbury. Blackwell said she did not have details on the fifth fatality.

In Michigan, 11 people were injured when a storm struck Monroe County, Michigan, and damage to the exterior wall of the Fermi 2 Nuclear Power Plant prompted an automatic shutdown, said Dan Smith, spokesman for the county's emergency management division. The plant will remain closed until crews have assessed the damage, he said.

Ten people were taken to hospitals by ambulance, and one was flown, after the storm struck about 3 a.m. Sunday, Smith said. Field crews were assessing the number of homes and businesses damaged in Dundee Village and Dundee Township, he said.

Up to 500 people staying at a water park resort were evacuated safely to a middle school, Smith said.

Several other communities in Illinois were hard-hit by severe weather. The town of Streator, Illinois, looks "like a war zone," Mayor Jimmie Lansford said. A total of 50 people were triaged, and 17 were transferred to hospitals and later released, Lansford said.

Thirty homes sustained major damage, and several others had minor damage, Lansford said. Animal rescue officials were set to begin searching through the rubble.

Officials are not sure whether the damage was caused by a tornado, pending confirmation by the National Weather Service, he said. "All we know is, it cut a path from the west side of town all the way through to the east side of town."

Many trees and power lines were downed, he said, and "a couple of businesses sustained some damage but we don't know to what extent."

"If it would have been two blocks farther north, St. Mary's Hospital would have been right in the path and it would have been devastating," Lansford said. "It could have been a lot worse."

A tornado touched down in Elmwood, Illinois, Saturday night, according to the Peoria County Sheriff's Office. Pictures from CNN affiliate WMBD showed a twisted gas station awning and streets covered with debris, branches and broken glass. The tornado ripped through downtown Elmwood, tearing the second stories off buildings in some cases, WMBD said.

Footage of storm damage across several states showed buildings with roofs ripped off, other structures reduced to rubble and overturned school buses and RVs.

The severe weather may continue Sunday, forecasters said, as there is a moderate risk of severe storms and tornadoes over areas of the northeastern United States. A tornado watch, meaning conditions are favorable for tornadoes, was issued until 8 p.m. Sunday for an area stretching from New Hampshire and Vermont southward to Virginia. The watch includes the cities of Boston, New York, Philadelphia, Baltimore and Washington.
