The Canadian Lightning Danger Map (CLDM) highlights areas that are at the greatest risk of being struck by lightning in the next 10 minutes. It is based on lighting strikes that have been recorded in the past 20 minutes.  An FAQ is provided to help you learn more about what you can do to protect yourself. A video of "How to Use the Canadian Lightning Danger Map" will be available in June 2013.
