KANKAKEE, Ill. (AP) — Major storms whipped up tornadoes that killed at least two people in northwest Indiana and leveled buildings in Kankakee, Illinois, authorities said Wednesday, as another round of rain, hail and strong winds made its way through the region.

Several intense supercell thunderstorms moved across northern Illinois and northwestern Indiana the previous day, including one responsible for at least four tornadoes, according to the National Weather Service office in Chicago.

The Newton County Coroner’s office said Edward L. Kozlowski, 89, and his wife Arlene Kozlowski, 84, were killed when a tornado struck their home in Lake Village, in northwestern Indiana. The couple appeared to have been killed by blunt force trauma, the coroner’s office said, and an autopsy was scheduled for Friday.

“They were wonderful, just really wonderful human beings,” son-in-law Steve Rehfeldt told CBS News in Chicago. “You know, tough old guy and sweet old lady.”

They left behind four children, seven grandchildren and great-grandchildren.

The storms shattered windows, tore off roofs and smashed vehicles in Kankakee, Illinois. Wood planks and other debris littered yards, streets and parking lots. A landscape and garden center was seriously damaged, some parts completely destroyed.

Storms also dropped 1 to 2 inches (2.5 to 5 centimeters) of rain and left piles of hail in the Grand Rapids area in western Michigan, said Alex Manion, a weather service meteorologist in Detroit. Streets flooded, swamping cars with water above their doors in some places.

The weather service said crews were determining the strength and number of tornadoes, and parts of Illinois, Indiana, Kentucky and Ohio remained under a tornado watch Wednesday.

Suspected tornadoes last week killed four people in southwestern Michigan and two in eastern Oklahoma.

In Lake Village, where the Kozlowskis died, crews rescued some people who were trapped in damaged homes. At least 70 utility poles were knocked down and many roads were rendered unpassable, Newton County officials said.

“Please do not come here. Do not try to help right now,” Sheriff Shannon Cothran said in a video shot in front of a destroyed home.

Laurie Postma, a spokesperson for the Lake Township Volunteer Fire Department, said the storm injured less than 10 people in Lake Village. Cothran said no other significant injuries had been reported but search and rescue operations were continuing.

Lake Village is about 60 miles (95 kilometers) southeast of Chicago and 25 miles (40 kilometers) east of Kankakee.

Resident says not all warning sirens sounded

David Ferris of Lake Village said he, his wife, and their dogs “rode it out in our downstairs bathtub.” They were unscathed, except for losing power. Ferris, who is a paramedic, helped rescue and treat injured people.

“We had another house where a guy crawled out,” Ferris said. “He was having some trouble breathing because he was covered in house insulation.”

Ferris said a Family Dollar store and a gas station were destroyed, and multiple large trees were uprooted.

Newlywed Cassidy Sinwelski, 23, said she and her husband were aware of the tornado watch in their Lake Village neighborhood and were expecting a run-of-the-mill storm until her husband spotted dark clouds barreling toward them.

“We went into the bathroom, got a piece of plywood and within minutes, I closed my eyes, the lights flickered, and we just — there was nothing,” Sinwelski said.

Then she heard loud rumbles and the sound of shattering glass.

“I just kept crying out for God, because I didn’t know what else to do,” she said.

Jennifer Telford, 49, said she hid in her basement in Lake Village while she followed news reports of the storm. She did not hear the tornado, which struck to the south, but heard the hail pelting her roof.

“The siren in town didn’t go off,” she said. “The sirens outside town did.”

The power was back on in the morning at the truck stop where she works, but elsewhere, “everything is closed due to the downed trees and power lines.”

About 4,300 customers in Lake Village and surrounding communities were without power late Wednesday morning, down from more than 11,000 at the peak of the storm, the Northern Indiana Public Service Co. reported.

In Kankakee, the storms produced exceptionally large hail, ranging from 3 to 5 inches (7.6 to 12.7 centimeters) in diameter. One 6-inch (15.2-centimeter) hailstone may have set a new state record, the weather service said.

A tornado touched down near the fairgrounds before traveling northeast into the small suburb of Aroma Park, where it caused extensive damage, the Kankakee County Sheriff’s Office said.

Nine people in the county had minor injuries, officials said at a news conference. Kevin Birk, a meteorologist in the NWS Chicago office, confirmed at least one tornado touched down in the area.

The storm shattered a longtime garden center’s spring plans

Tholens’ Garden Center on the south side of Kankakee was hit hard by the tornado, owner Nancy Tholen said.

“We have multiple buildings, and lots of them are destroyed,” Tholen said. “This is our 50th year in business, and this was not how we planned to kick off our spring.”

Workers had just left for the day when the tornado hit Tuesday afternoon, she said. Thankfully, no one was hurt.

“You know, we make our living in the next 12 weeks,” Tholen said. “We’ll figure something out to open, but it’s just … it’s crazy. But again, everybody’s safe, so we’re thankful for that.”

In Aroma Park, just southeast of Kankakee, restaurateur and village trustee Kathleen Slavin watched the destruction of the tornado and “baseball-sized hail” from the village hall, where she attended a village board meeting.

“It took down trees that are probably over a hundred years old, huge trees came down. It took out main power lines,” Slavin said.

Her friend, 69-year-old Ruth Denoyer, swept up glass after the tornado blew out her windows.

“It took our whole garage down, our pool, we have broken windows in the house, glass everywhere.” Denoyer said. “But we still have a roof, unlike some people out here.”
