How should you respond to a weather alert?
When an alert is issued for your region, take it seriously. For a warning, take shelter or postpone travel. For a watch, stay informed and prepare to act. Keep a Canada weather warnings page open, and check the Canada weather hub for regional forecasts. Ensure your emergency kit is stocked and that you have a battery-powered radio or reliable cellular service to receive updates.
What is the difference between a weather watch and a warning?
A watch means conditions are favourable for hazardous weather to develop; a warning means the hazardous weather is imminent or occurring. Take action on a warning; stay alert during a watch.
How can I get weather alerts on my phone in Canada?
Enable Wireless Public Alerting on your mobile device – it uses cell-broadcast technology to deliver emergency alerts automatically, including weather warnings from Environment Canada. No app needed.
Should I drive during a weather warning in southern Ontario?
Only if absolutely necessary. Toronto weather snow storm warnings often bring rapidly deteriorating roads. If you must go, reduce speed, use winter tires and carry an emergency kit.
