At least 18 people were killed Sunday by three separate tornadoes spawned by a powerful storm system that moved through the central and southern United States. The Arkansas Department of Emergency Management confirmed early Monday that at least sixteen people had died after a tornado tore through central Arkansas, while an Oklahoma county sheriff’s dispatcher reported that one person had died in the town of Quapaw, near the state’s borders with Kansas and Missouri. Fox News has also confirmed that one person died when a tornado hit Keokuk County, Iowa. The Arkansas tornado touched down about 10 miles west of Little Rock at around 7 p.m. local time and moved northeastward for at least 30 miles, the National Weather Service reported. It missed the state capital but passed through or near several of its suburbs, causing widespread damage in the communities of Mayflower and Vilonia.
