How to use the public weather alert maps and tables

New and Improved Alert Maps and Tables

The alert map displays all forecast regions in Canada, with coloured regions indicating those regions with alerts in effect. The new and improved alert maps and table now include the alert type “special weather statement” along with warnings and watches. The special weather statement will be identified on the maps by the dark grey colour, and will be listed in the table below the maps under the new header “statement”.

The new and improved table below the alert maps lists all forecast regions with alerts in effect. Selection can now be made at the level of a province or territory, a region or an event name. Selecting a province or territory name will take the user to that province or territory alert page, which includes a table listing all regions with alerts in effect. This is the same as clicking on a province or territory on the National alert map. Selecting a region name will take the user to the top of the region alert page. Selecting the event name will take the user to the details for that event in that region’s alert page.



On the provincial or territorial map, the user can click on a region on the map and be taken to the alert listing page for that region. The alert listing page will give a summary, in chronological order, of all alerts in effect for that region.
