Prepare for a storm

Preparing your home and neighborhood before a storm can help reduce potential damage.

  • Cut down or trim trees that may be in danger of falling on your home.
  • Consider buying surge protectors, lightning rods, or a lightning protection system to protect your home, appliances, and electronic devices.


During thunderstorms & lightning

Seek shelter from wind & lightning

  • Get inside a home, building, or car.
  • You're much safer inside a vehicle than outside.

Avoid contact with electricity & plumbing

  • Don't touch electrical equipment or cords that are plugged in.
  • Don't wash your hands, shower, or wash dishes. Plumbing and bathroom fixtures can conduct electricity.

Avoid flood waters

  • Move to higher ground.
  • Don’t walk or drive through flood waters. 
  • If water rises around your car, abandon the car immediately.
