Lightning strikes the United States about 25 million times a year. Although most lightning occurs in the summer, people can be struck at any time of year. Lightning kills an average of 49 people in the United States each year, and hundreds more are severely injured.

Lightning: What You Need to Know

• Stay in safe shelter at least 30 minutes after you hear the last sound of thunder.

Indoor Lightning Safety

• Avoid plumbing, including sinks, baths and faucets.
• Do not lie on concrete floors, and do not lean against concrete walls.
