Storms raged across the United States this weekend, claiming the lives of at least 32 people, destroying homes and livelihoods as it cut a swath of destruction through the South and Midwest.
An estimated 50 tornadoes struck, from Illinois to New Jersey, Arkansas to Michigan.
In tragic scenes, two children and an adult were found dead on Saturday in Memphis after winds knocked trees onto several houses, according to the Memphis Police Department. The bodies of a couple were found at a campground in McCormick's Creek State Park. Nine of the deaths in Tennessee were in buildings that were destroyed, per NBC News.
Another 15 deaths from the storm, which generated tornadoes in several areas, were earlier reported in Arkansas, Illinois, Indiana, Delaware, Mississippi and Alabama.
Dr. Jenna Houser from The Ohio State University told KCBS that it's not unusual to have an active March and April in terms of severe storms and tornadoes. But how far north the deadly storms spread at this time of year is unusual.
"This time of year is a little bit more typical for the southeastern portion of the United States and the areas that were kind of the southern side of that -- Arkansas Tennessee, Alabama Mississippi, and so forth. But the northward extent of that, the most recent severe storm outbreak, is so, so incredibly unique," Dr. Hauser said.
President Joe Biden declared a "major disaster" in Arkansas on Sunday and said federan money will help rebuild the disaster-struck areas.
"We know families across America are mourning the loss of loved ones, desperately waiting for news of others fighting for their lives, and sorting through the rubble of their homes and businesses," he said.
North Texas suffered hail, significant wind gusts and a "strong tornado or two," with weather raging so hard that Dallas Fort Worth International Airport was under a ground-stop order for hours on Sunday.
And there's more on the way, with severe weather coming for Texas, Oklahoma and moving toward Ohio, Illinois and Michigan. Gusts of up to 50 mph are expected to strike the Bay Area in California.
"It's almost a rinse and repeat of what we just had," Dr. Hauser said.
