Wisconsin averages 21 tornadoes a year. The peak tornado season is April to August, but they can occur any time of year. About 80% of tornadoes that hit Wisconsin are relatively weak, with winds under 100 mph. Only 1% are violent with winds over 200 mph.
Tornado safety before the storm includes:
- Develop a plan for you and your family for home, work, school and outdoors. Know the safest shelter areas in multiple locations.
- Have frequent drills.
- Keep a disaster supply kit in your home including water, food that won't spoil and needs no heat to serve, first-aid kit, NOAA weather radio, a flashlight and special items for children, pets and elderly family members.
- Be sure your weather radio is working properly. Spring is a great time to install fresh batteries.
