Canadian Mesonet Portal Update! ⚡
The new Severe Storm Summaries feature automatically compiles a 24-hour overview of severe weather activity across Canada by combining multiple datasets (lightning, weather stations, alerts, radar-indicated severe weather signatures) into a single interactive map!
We are currently implementing a large update to the Canadian Mesonet Portal (meso.cssl.ca), which will result in data being temporarily unavailable for the next 24 hours. Please be patient with us as we work to make the site even better!
