What 3 Inch Plus Hail Does to Property

3 inch or larger hail is golf ball to baseball size and beyond, representing some of the most destructive hail possible from a severe thunderstorm. At this size, hail will total vehicles instantly, shatter windows, punch through roofs, destroy solar panels and injure or kill anyone caught outdoors. The Level 4 Moderate zone centered on Wichita and Topeka faces this extreme hail threat on Monday, May 18. Move all vehicles under solid cover before Monday afternoon.

Cities Inside the Level 4 Moderate Zone

EF2 to EF3 Tornadoes Are a Life-Threatening Risk

An EF2 tornado carries winds of 111 to 135 mph while an EF3 reaches 136 to 165 mph, both capable of destroying homes, overturning vehicles and producing life-threatening flying debris across wide areas. The Moderate risk zone for Monday, May 18 highlights EF2 to EF3 or stronger tornadoes as a real possibility for Wichita, Topeka, Omaha and Hastings. Anyone in these cities must have a confirmed tornado shelter plan before Monday morning.
