Although a severe thunderstorm can without much warning, you can take some safety precautions to plan ahead. To prepare for severe thunderstorms:

  • Secure outdoor objects that could blow away or cause damage. Remove dead or rotting trees and branches that could fall and cause injury or damage during a severe thunderstorm.
  • Shutter windows and secure outside doors. If shutters are not available, close window blinds, shades or curtains.
  • Listen to local news or a weather radio for emergency updates. Watch for signs of a storm, like darkening skies, lightning flashes, or increasing wind. If you can hear thunder, you are close enough to be in danger from lightning. If thunder roars, go indoors!
  • If a storm is approaching, get inside a home, building, or hard top automobile (not a convertible).
  • If you are outside and cannot reach a safe building, avoid high ground; water; tall, isolated trees; and metal objects such as fences or bleachers. Picnic shelters, dugouts and sheds are NOT safe.
  • If you are driving, try to safely exit the roadway and park. Stay in the vehicle and turn on the emergency flashers until the heavy rain ends.
  • Keep away from windows.
  • Avoid electrical equipment and corded telephones. Cordless phones, cell phones and other wireless handheld devices are safe to use.
