American Red Cross Offers Severe Thunderstorm Safety Tips. The Tulsa Area Chapter American Red Cross urges Tulsa-area families to take caution during severe thunderstorms.
Every thunderstorm produces lightning, which kills more people each year than tornadoes.
Heavy rain from thunderstorms can lead to flash flooding. Strong winds, hail, and tornadoes are also dangers associated with some thunderstorms. Look for darkening skies, flashes of light, or increasing wind. Listen for the sound of thunder. Go to safe shelter immediately.
