Thunderstorm Prep

Thunderstorms can includes powerful winds over 50 MPH, create hail, include intense lightning, and cause flash flooding & tornadoes.

Prepare NOW

  • Know your area’s risk for thunderstorms. In most places, they can occur year-round and at any hour.
  • Sign up for your community’s warning system. The Emergency Alert System (EAS) and National Oceanic and Atmospheric Administration (NOAA) Weather Radio also provide emergency alerts. 
  • Identify nearby, sturdy buildings close to where you live, work, study, and play. 
  • 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.

Survive DURING

  • When thunder roars, go indoors. A sturdy building is the safest place to be during a thunderstorm.
  • Pay attention to weather reports and warnings of thunderstorms. Be ready to change plans, if necessary, to be near shelter.
  • When you receive a thunderstorm warning or hear thunder, go inside immediately.
  • If indoors, avoid running water or using landline phones. Electricity can travel through plumbing and phone lines.
  • Protect your property. Unplug appliances and other electric devices. Secure outside furniture.
  • If boating or swimming, get to land and find a sturdy, grounded shelter or vehicle immediately.
  • If necessary, take shelter in a car with a metal top and sides. Do not touch anything metal.
  • Avoid flooded roadways. Turn Around. Don’t Drown! Just six inches of fast-moving water can knock you down, and one foot of moving water can sweep your vehicle away.

Be Safe AFTER

  • Listen to authorities and weather forecasts for information on whether it is safe to go outside and instructions regarding potential flash flooding.
  • Watch for fallen power lines and trees. Report them immediately.
