Stay Safe during Severe Storms

Michigan weather can be unpredictable. Here are some tips for how to stay safe during severe storms:

During a Tornado

  • Go to a basement, safe room, or interior room on the lowest floor away from windows.
  • Avoid large open areas like gyms, auditoriums, or cafeterias.
  • If outside, seek shelter in a sturdy building immediately.
  • If you are in a vehicle and cannot reach shelter, protect your head and seek a low-lying area such as a ditch if safe to do so.

During a Severe Thunderstorm

  • Move indoors immediately and stay away from windows.
  • Avoid large open spaces where debris could pose a hazard.
  • If outdoors, do not take shelter under trees, which increase lightning risk.
  • Vehicles can provide temporary shelter if you cannot reach a building.

Lightning Safety

  • Lightning can strike miles from a storm. Remember: “When Thunder Roars, Go Indoors.”
  • Move inside a building or enclosed vehicle.
  • Avoid plumbing, electrical appliances, and wired electronics.
  • Stay inside for 30 minutes after the last thunderclap.

During Flooding

  • Floodwaters can rise quickly and be extremely dangerous.
  • Move to higher ground immediately if flooding occurs.
  • Never walk through floodwaters — six inches of moving water can knock you down.
  • Never drive through flooded roads. Just 12 inches of water can carry away a vehicle.
  • Follow evacuation orders and monitor local weather updates.
