Clint Blevins captured stunning footage of lightning strikes off of Florida’s Daytona Beach in June 2015. In slow motion, the video clearly shows strikes in the distance rapidly followed by a much closer strike that flares several times before fading, leaving a vertical streak of burning air.
The flaring is actually a series of secondary strikes. “It is very possible that a main strike can be followed by 30 or 40 secondary strikes,” says an April 2000 article inHowStuffWorks. “Depending on the time delay between strikes, we may see what looks like one long-duration main strike, or a main strike followed by other flashes along the path of the main strike.”
