Thunderstorms are a common and potentially dangerous weather phenomenon across the United States. Understanding and implementing safety measures can significantly reduce the risks associated with these storms.

What Are Thunderstorms and Why Are They Dangerous?

A thunderstorm is a rain-bearing cloud system that produces lightning and thunder. These storms can lead to severe weather conditions, including heavy rainfall, strong winds, hail, and tornadoes. The dangers associated with thunderstorms include:

Lightning Strikes: Lightning can cause fires, power outages, and injuries.
Flooding: Heavy rainfall can lead to flash floods, especially in low-lying areas.
Strong Winds: High winds can uproot trees, damage structures, and pose risks to vehicles.
Hail: Hailstones can damage crops, vehicles, and roofs.

How Can I Stay Safe Indoors During a Thunderstorm?

Staying indoors during a thunderstorm is the safest option. To protect yourself:

Avoid Water: Do not bathe, shower, wash dishes, or have any other contact with water during a thunderstorm because lightning can travel through a building’s plumbing. (cdc.gov)
Stay Away from Windows and Doors: Keep away from windows and doors, and stay off porches. (cdc.gov)
Avoid Electrical Appliances: Do not use corded phones or electrical appliances. (cdc.gov)

What Should I Do if I'm Outdoors During a Thunderstorm?

Seek Shelter Immediately: When thunder roars, go indoors. (cdc.gov)
Avoid Water: Get out of and away from ponds, lakes, and other bodies of water. (cdc.gov)
Stay Away from Tall Objects: Avoid tall structures such as telephone poles and trees; lightning tends to strike the tallest object around. (cdc.gov)
