What types of weather warnings does Canada issue?
Environment Canada categorises alerts into warnings, watches, and advisories. Warnings mean hazardous weather is occurring or imminent; watches indicate conditions are favourable for a storm to develop; advisories cover less severe but still disruptive events like blowing snow or poor air quality. For specific regions, ontario weather warnings today often include lake-effect snow in the south and blizzard conditions in the north.
How can I use the Canada weather warnings map?

What is the difference between a warning and a watch?
A warning means the hazardous weather is already happening or will occur within hours. A watch means conditions are possible within the next 24 to 48 hours, so you should stay informed and prepare.
How often are Environment Canada weather warnings updated?
Warnings are updated as conditions change, often every few hours during active weather. Critical updates may come more frequently for fast-moving storms like tornadoes.
