When Lightning Strikes

Lightning and thunder occur simultaneously, but because light travels faster than sound, we see lightning first. Count the seconds between a flash of lightning and a clap of thunder and divide by five to estimate how far away in miles the storm is. Divide by three for kilometers. While dope to observe, do not observe too close, lightning kills more people on an annual basis than tornadoes, hurricanes or winter storms. It is second only to flash floods in the annual number of deaths caused by storm-related hazards.
