Storm safety tips: how to prepare for a storm

Thunderstorms are caused by an unstable moisture-filled air mass and the rising and falling atmospheric motion known as a convection cell. All thunderstorms are accompanied by lightning, however, you may see bolts of lightning in the sky without hearing thunder. About 100,000 thunderstorms occur across the U.S. every year, and of these, about 10% are considered severe. Rainfall associated with thunderstorms can cause flash flooding, which is responsible for more deaths annually than hurricanes, tornadoes, or lightning. While the chance of getting hit by lightning in the U.S. is one in 700,000, a strike can be fatal or result in permanent physical and behavioral side effects. And fire departments in the U.S. respond to an estimated 22,600 fires started by lightning every year. In addition, thunderstorms are associated with strong winds (up to more than 120 mph) that can knock down trees, power lines, and mobile homes. Listening to weather forecasts and planning ahead are two essential steps for staying safe when a storm hits.
