Safety Tips

If you are in a vehicle...

  • Stop driving.
  • If you can see a safe place close-by to drive to (like inside a garage, under a highway overpass, or under a service station awning), do so as soon as you can.
  • Make sure you pull completely off the highway.
  • Do NOT leave the vehicle until it stops hailing. Your car will furnish reasonable protection.
  • Cover your eyes.
  • If possible, get onto the floor face down, or lay down on the seat with your back to the windows.
  • Put very small children under you, and cover their eyes.

If you are in a building...

  • Stay inside.
  • Don’t go into the basement.
  • Stay away from windows, especially those being struck by hail.
  • Account for all family members, building occupants, pets, etc.
  • Do not go outside for any reason.
  • Avoid using telephones and electrical appliances during a severe storm to avoid the danger of electrocution from lightning.

If you are outdoors...

  • Seek shelter immediately.
  • If you can’t find something to protect your entire body, at least find something to protect your head.
  • Trees are a last resort. It is common during severe storms for trees to lose branches. Also, large isolated trees attract lightning.
  • Keep away from areas with deep hail.
  • Try to find shelter from deep hail and lightning.
  • Stay out of culverts and lowland areas to avoid being swept away by water or deep hail.
