In addition to being able to subscribe to Watches and Warnings issued by Environment Canada, as well as view the details of the alert, you can now subscribe to Weather Bulletins.
These are issued by Environment Canada and are of a more generic nature than the watches and warnings. They'll contain information about weather that may not warrant issuing a watch or warning, but can still affect your day. You'll see the option to subscribe to areas throughout the country on the User Menu while logged in.
