Current lightning data, updated every 60 seconds! A red "+" indicates a strike within the last 60 seconds; a yellow "." indicates a strike between 1 and 10 minutes ago. For a loop of images over the past hour, click here.
Please note: the strikes you see at the bottom of the screen when in the 100 or 200 mile display, and in southern Illinois and southern Indiana at the 300 mile display are electrical interference and should be ignored.
