The toll is probably higher, as recent studies have shown that many lightning accidents go unreported. This causes a rapid expansion of the air which produces thunder. A single lightning stroke also contains an enormous amount of electricity, enough to supply power to several homes for a month. The heat and electricity pose the greatest risk to the individual. Most lightning deaths and injuries occur when people are caught outdoors.
Lightning also causes many grassland and forest fires in Colorado.
Stay alert for fast-changing weather conditions. It does not have to be raining where you are for lightning to be a threat. Many people are struck before the rain begins or after it ends at their location. Avoid being the tallest object in the area , and stay away from other tall objects such as a small group of tall trees. Unplug all unnecessary appliances and stay off the phone.
