How to read this map:
This map is displaying the current and past 30 or 60 minutes of lightning strikes

The image below is a screenshot of current lightning data and updated every 5 minutes. On this image, calculated locations of thunderstorms can be seen. Based on classification criteria, a green, yellow or red diamond will appear where thunderstorm locations are predicted by the detector software.  The map will automatically adjust the range to provide the best view of the current activity from 25 - 1200 km.
