    To reduce your risk of injury or death: 

    • 30/30 Rule: If you hear thunder within 30 seconds after seeing the flash, move indoors quickly and stay inside until 30 minutes after the last thunder.
    • The Flash to Bang Lightning Distance Calculator: If you see lightning, count the seconds until you hear thunder, then divide by 5. This is how far in miles the lightning is away from you. Any distance less than 10 miles puts you in danger. Seek shelter immediately.
    • Stay away from windows, doors, plumbing, appliances, electronics or anything that conducts electricity.
    • Do not take a shower, bath or hot tub if you hear thunder or for 30 minutes after.

    An enclosed vehicle with metal roof and sides is the next best alternative if no safe building is available. Roll up the windows and avoid contact with the radio, CB and ignition.

    If you are outside and feel your hair stand on end, squat down, tuck your head low and cover your ears.
