Lightning can strike up to 10 miles from a storm, averaging 2-3 miles between strikes. It travels at 100 million volts and over 100,000 amps, generating temperatures over 54,000 degrees Fahrenheit. To estimate how far away a lightning strike is, count the seconds between seeing the flash and hearing the thunder, as sound travels about 1 mile every 5 seconds. Proper lightning protection systems use air terminals to intercept strikes, conductors to guide current to ground, grounding rods, and surge protectors to mitigate damage.

2. Facts about Lightning A strike can average 100 million volts of electricity Current of up to 100,000 amperes Can generate 54,000 o F Lightning strikes somewhere on the Earth every second Kills 100 US residents per year

3. Lightning Doesn’t Go Straight Down

4. What Does This Mean? Lightning can strike ground up to ten miles from a storm ( Lightning out of the blue ) There is an average of 2-3 miles between strikes So how can we tell how far away lightning has struck?

5. Use The Five Second Rule Light travels at about 186,291 miles /second Sound travels at only 1,088 feet /second You will see the flash of lightning almost immediately 5280/1088= 4.9 About 5 seconds for sound to travel 1 mile
