Thunderstorm Safety Cheat Sheet: Essential Guidelines for Protection

Thunderstorms are a common and potentially dangerous weather phenomenon in the United States, capable of producing lightning, hail, strong winds, and even tornadoes. Understanding how to stay safe before, during, and after a thunderstorm is crucial.

What Are Thunderstorms?

A thunderstorm is a rain-bearing cloud system that produces lightning and thunder. Severe thunderstorms are defined as storms capable of producing hail one inch or larger in diameter or wind gusts over 58 mph. These conditions can lead to property damage, power outages, and pose significant risks to personal safety. (weather.gov)

  • Create an Emergency Plan: Establish a family emergency plan that includes communication strategies and designated safe locations within your home.

  • Assemble an Emergency Kit: Prepare a kit with essentials such as a flashlight, batteries, first aid supplies, non-perishable food, water, and important documents.
