President Joe Biden Saturday said he was briefed on the “devastating tornadoes” across the central United States. “To lose a loved one in a storm like this is an unimaginable tragedy,” Biden tweeted. The affected states would “have what they need as the search for survivors and damage assessments continue,” he said. At least seven people were killed overnight as a storm system battered a candle factory in Kentucky, an Amazon facility in Illinois and a nursing home in Arkansas. Kentucky Governor Andy Beshear said he feared dozens more could be dead as about 110 people were in the factory in Mayfield when the tornado hit.

“We believe our death toll from this event will exceed 50 Kentuckians and probably end up 70 to 100,” Beshear said at a news conference Saturday. “It’s very hard, really tough, and we’re praying for each and every one of those families.”

At least one person died at an Amazon facility in Edwardsville, Illinois, Police Chief Mike Fillback told reporters Saturday morning. Two people at the facility were taken by helicopter to hospitals in St. Louis, Fillback said.

The National Weather Service office near St. Louis reported “radar-confirmed tornadoes” in the Edwardsville area around the time of the collapse.“The safety and well-being of our employees and partners is our top priority right now,” Amazon spokesperson Richard Rocha said in a written statement Friday night. “We’re assessing the situation and will share additional information when it’s available.”

Workers at a National Weather Service office had to take shelter as a tornado passed near their office in Weldon Spring, Missouri, about 30 miles (48 kilometers) west of St. Louis. One person died and two others were injured in building collapses near the towns of Defiance and New Melle, both just a few miles from the weather service office.

A tornado struck the Monette Manor nursing home in Arkansas on Friday night, killing one person and trapping 20 people inside as the building collapsed, Craighead County Judge Marvin Day said.
