With at least 25 people dead in Mississippi, tornadoes that ravaged parts of the Deep South overnight were the deadliest in the state in more than a decade, according to National Weather Service records.

By comparison, 31 people died in Mississippi in April 2011 during tornadoes that tore through several states, mostly in the southeastern U.S., weather service meteorologist Chris Outler said Saturday. Alabama was hit hardest during that so-called “super outbreak” of hundreds of twisters that killed more than 320 people and caused an estimated $12 billion in damage.

Just a month later, another deadly twister ripped through Joplin, Missouri, killing 158 people. Outler, in Las Vegas, called 2011 “the headline year for tornadoes for the last 20 years or so."

The sheriff's office in Morgan County, Alabama, reported one storm-related death on Saturday, bringing the overall total during overnight storms to at least 26.

Records show that 12 people died in Mississippi during Easter storms in April 2020, and 10 died in the state during a tornado event in April 2014.
