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 on Tuesday, including one responsible for at least four tornadoes, according to the National Weather Service office in Chicago.

The storms shattered windows, tore off roofs and smashed vehicles in Kankakee. 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 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, leaving a cars stranded with water up past their doors in some places.

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

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

The storm spawned a tornado that killed an elderly couple in their home in Lake Village, in northwestern Indiana, Newton County Coroner Scott McCord said. Their names have not been released.

Crews rescued some who were trapped in their damaged homes, at least 70 utility poles were knocked down and many roads are unpassable, Newton County officials said Wednesday morning.

“Please do not come here. Do not try to help right now,” Sheriff Shannon Cothran said in a video update Tuesday night in front of a destroyed Lake Village 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 Wednesday that no other significant injuries have been reported but that search and rescue operations continue.

Lake Village is about 60 miles southeast of Chicago and 25 miles west of Kankakee County, Illinois, where at least one tornado struck Tuesday night.

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 to 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.

Jennifer Telford, 49, said she hid in her basement in Lake Village, from where she followed news reports of the storm. She didn’t hear the tornado that struck to the south, but said she heard the hail as it pelted her roof.

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

She said power had been restored at the truck stop where she works Wednesday morning but that 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 customers at the peak of the storm, the Northern Indiana Public Service Co. said on its website.
