Tornadoes have slashed across the U.S. South and Midwest over the past two days, leaving at least 31 dead, while 75 million Americans remain under severe weather warnings. More tornadoes may come Tuesday night.
Many in affected areas have taken to social media to record the devastation. (Related: "How Scientists Hope to Improve Tornado Forecasting.")
Here are some of the powerful pictures on Facebook, Twitter, and Instagram:
A spate of tornadoes caused by massive thunderstorms has left a wake of destruction in parts of the South and Midwest.
On Sunday the hardest-hit area was central Arkansas's Faulkner County, where 11 people—including two children—were killed in the towns of Mayflower and Vilonia. Homes were smashed and trucks were tossed through the air.
A tornado was spotted just west of Joplin, Missouri, on Sunday. The town was devastated by a massive tornado in May 2011.
Damage and debris are scattered in Baxter Springs, Kansas, just north of the border with Oklahoma.
Most tornadoes are birthed by large rotating thunderstorms called supercells, like this one pictured near Brooksville, Mississippi, last weekend.
In this Instagram image said to be from Louisville, Mississippi, the poster writes that five people survived inside a flattened two-story home. "Their little dog was sucked out by the tornado but showed back up alive hours later," the user wrote.
This photo is said to depict some of the widespread devastation in Mayflower, Arkansas, about 25 miles (40 kilometers) northwest of Little Rock.
