When thunder roars, go indoors. Move into a building or a car with a roof, and do not drive through flooded roads.
Before
Sign up for your community warning system and use NOAA Weather Radio. Trim trees that could fall on your home and consider surge protectors or a lightning protection system. Identify sturdy buildings near where you live, work, study and play.
During a warning
Move into a building or a car with a roof, pay attention to alerts, and avoid plugged-in electronics and running water.
After
Follow authorities and forecasts on whether it is safe to go outside and on possible flash flooding. Watch for fallen power lines and trees and report them.
