You can determine the distance of an approaching thunderstorm by counting the number of seconds between the lighting flash and the thunder clap, and dividing by five. This will give you the distance in miles you are from the storm. Lightning does not strike just during the height of the thunderstorm. In fact, the greatest danger often comes with the first or last flash, when people least expect it. Florida leads the nation in lighting deaths and injuries.
Some locations are more dangerous than others.
The greatest number of people are struck while near a body of water. This includes people at the beach, near lakes, on fishing piers, and in small boats. Another vulnerable location is an open area with a few trees around, such as a ball field, playground or golf course. Become familiar with lighting safety rules an save your life or that of a loved one. Avoid leaning against vehicles.
