Map of Lightning Strikes in Close to Real Time

Approximately 25 million lightning strikes occur in the United States each year; slightly less that one per second. You can see what this means at blitzortung.org. Using data collected from detectors around the country, the website’s map emits a click and flashes a circle every time lightning strikes. The colored dots indicate where lightning has struck within the past two hours or┬áless. And an overlay of green lines show the detectors that help triangulate the event. It is entertaining to watch and can help you understand the danger of lightning strikes.
