Before a Thunderstorm



Know the Terms


  • Familiarize yourself with the terms that are used to identify a thunderstorm hazard, including understanding the difference between a severe thunderstorm watch and a severe thunderstorm warning.
  • A severe thunderstorm watch means there is the potential for severe thunderstorms (damaging winds/large hail) to impact your area within the next 6 hours.
  • A severe thunderstorm warning means a severe thunderstorm is occurring or will likely occur soon. If you are advised to take shelter, do so immediately.
  • Note, a severe thunderstorm refers to a thunderstorm producing winds of 58 mph or greater, 1-inch (quarter) sized hail or larger, and/or a tornado. Although lightning can be deadly, severe thunderstorm watches and warnings are not issued specifically for lightning.

Take Action


  • Remove dead or rotting trees and branches that could fall and cause injury or damage during a thunderstorm.
  • Know your lightning safety rules. For example, if you hear thunder or see lightning, go indoors. Stay indoors for at least 30 minutes after hearing the last clap of thunder.
  • If thunderstorms are expected in your area, postpone outdoor activities.
  • Secure outdoor objects that could blow away or cause damage.
  • Shutter windows and secure outside doors. If shutters are not available, close window blinds, shades, or curtains.

During a Thunderstorm


  • If there is a thunderstorm in the area, go quickly inside a home, building, or hard top automobile, if possible.
  • If shelter is not available, go to the lowest area nearby and make yourself the smallest target possible but do not lie flat on the ground.
  • If on open water, get to land and shelter immediately.
  • Listen to a battery-operated NOAA Weather Radio or radio for the latest updates.
  • Avoid taking a shower or a bath during a thunderstorm. Plumbing and bathroom fixtures can conduct electricity.
  • Do not use electrical items such as computers or television sets as power surges from lightning can cause serious damage.
  • A corded telephone should only be used in an emergency, but cordless phones and cell phones are safe to use.
  • Things to avoid include:
    • A tall, isolated tree in an open area.
    • Hilltops, open fields, the beach, a pool, a boat on the water, isolated sheds or other small structures in open areas.
    • Anything metal, such as tractors, farm equipment, motorcycles, golf carts, golf clubs, and bicycles.

After a Thunderstorm



After the storm passes remember to:
  • Never drive through a flooded roadway. Turn around, don’t drown!
  • Stay away from storm-damaged areas to keep from putting yourself at risk from the effects of thunderstorms.
  • Stay away from downed power lines and report them immediately to your local power company.
