Hail is preciptation that is formed when updrafts in thunderstorms carry raindrops upward into extremely cold areas of the atmosphere. Large hail can indicate the presence of an unusually dangerous thunderstorm.

Hail can damage aircraft, homes, and cars; it can cause injury, and in rare cases death, to livestock and people.


As hail develops, get inside as quickly as possible

  • Close all drapes, blinds, and shades to prevent broken window glass and hail from getting inside.
  • If possible, move to a lower level and directly below the roof.
  • Stay indoors until the storm has passed.

You may be driving when the hail begins. Consider:

  • Stay in the vehicle unless you are able to safely take shelter.
  • When safe to do so, pull over.
    • Avoid ditches where water may rise and cause flooding.
  • Angle the vehicle so the hail is hitting the front of your car.
    • Front windshields are built to withstand pelting objects.
  • Keep your back to the windows.
    • Lie down, if possible.
    • Cover yourself with a blanket to prevent debris and glass from injuring you.
