How to Calculate the Distance of a Lightning Strike
Many people wonder how far away a lightning strike is during a storm. Using a basic math trick, you can estimate the distance by measuring the time between seeing the flash and hearing the thunder.
To do this, note the seconds between the lightning and the thunder. The general rule is that every five seconds corresponds to roughly one mile of distance from the storm. For example, if you count 10 seconds between the flash and the thunder, the storm is about two miles away.
This method provides a quick and easy way to gauge the proximity of a storm, helping you stay safe and informed during severe weather conditions.
