Lightning is a powerful electrical discharge that forms during thunderstorms when opposite charges build up between clouds and the ground. When the difference in charge becomes extremely high, electricity travels suddenly through the air as lightning.
A human can be struck when standing in an open area, under a tree, near water, or close to tall objects. The body can become part of the easiest path for electricity to reach the ground. Lightning may strike directly, jump from a nearby object (side flash), travel through the ground, or pass through metal and water.
When lightning strikes a person, it can cause severe burns, heart stoppage, nerve damage, unconsciousness, hearing loss, or even death. Some people survive but may suffer long-term health problems.
To stay safe, move indoors during thunderstorms, avoid trees and open fields, stay away from water, and do not touch electrical appliances or wired devices. If thunder is heard, lightning is close enough to be dangerous.
