In the piece, author Kevin Ambrose from the Capital Weather Gang investigates an unexpected lightning bolt that struck the ground near the Washington Monument last August. Using Ambrose’s photo and timestamp, Quick and Rudlosky determined that this was a compact flash of negative lightning produced by a rapidly dissipating storm. The flash was short but produced three ground contacts.
Quick states, “It’s important to note the lightning flash occurred about 10 minutes after the apparent end of the thunderstorm, a time period when an eager soccer coach may say that it is safe to play again. Wait 30 minutes after the last lightning.”
