Tornado watches and warnings have already been issued this year as severe weather continues to batter communities across the United States.
The National Weather Service in Springfield confirmed that a tornado with 80 mph winds briefly touched down near Iantha, Missouri, on March 6, marking what could be the first tornado in the state in 2026. No injuries were reported, but the storm caused major damage to a barn, with roofing materials thrown more than a mile away.
Here’s what to know about Missouri’s tornado season.

Tornado safety tips to know
You cannot do much to prevent property damage during a tornado, but you can take several precautions to reduce the risk of injury if a tornado touches down near you.
- If you cannot remain at home, make arrangements to go to a public shelter.
- Move to a safe shelter immediately, such as a safe room, basement, storm cellar, or a small interior room on the lowest level of a sturdy building.
- Stay away from windows, doors, and exterior walls.
- Do not take shelter under an overpass or bridge. You are safer in a low, flat area.
- Stay alert for flying debris, which can cause serious injury or death.
- Use your arms to protect your head and neck.
