Facts About Thunderstorms (Interesting & Fun)

Thunderstorms are fascinating natural phenomena that can occur in any season. Did you know that June is typically the most active month for thunderstorms? These powerful weather events can form in less than 30 minutes and last for hours, but on average, they last around 30 minutes and are roughly 15 miles wide.

One interesting fact about thunderstorms is that lightning kills and injures more people each year than hurricanes and tornadoes combined. It’s important to take thunderstorms seriously and be aware of the dangers they pose.

Another common misconception is the idea of “heat lightning.” There is actually no such thing. What people refer to as heat lightning is simply distant lightning from a thunderstorm occurring too far away for the thunder to be heard.

Hail is often associated with thunderstorms, but there are times when the hail melts before reaching the ground. Additionally, thunderstorm winds, also known as straight-line winds, can reach speeds of over 100 mph, causing significant damage.
