Severe Thunderstorms – What to Know

Thunderstorms are dangerous storms that include lightning and can:

  • Include powerful winds over 50 MPH;
  • Create hail; and
  • Cause flash flooding and tornadoes.

Lightning is a leading cause of injury and death from weather-related hazards.  Although most lightning victims survive, people struck by lightning often report a variety of long-term, debilitating symptoms.

IF YOU ARE UNDER A THUNDERSTORM WARNING, FIND SAFE SHELTER RIGHT AWAY

  • When thunder roars, go indoors!
  • Move from outdoors into a building or car.
  • Pay attention to alerts and warnings.
  • Unplug electronic devices (phones, TVs, computers).
  • Do not use landline phones.

HOW TO STAY SAFE WHEN A THUNDERSTORM THREATENS

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.
  • Cut down or trim trees that may be in danger of falling on your home.
  • Consider buying surge protectors to protect 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.
