As the seasons shift from the heat of summer to the unpredictable patterns of fall, severe weather in Canada becomes more common and potentially more dangerous. From heavy rain and windstorms to late-summer tornadoes and early snowfall, knowing the difference between a weather advisory, watch, and warning can help protect your home, family, and property.
Here’s what Canadians need to know about severe weather alerts and how to be prepared when Mother Nature turns.
Understanding Weather Alerts
1. Weather Advisory: A weather advisory is issued when conditions are expected to cause inconvenience or difficulty. While not immediately dangerous, advisories signal that caution is needed. Examples include strong winds, minor freezing rain, or reduced visibility from fog or smoke.
2. Weather Watch: A watch means conditions are favourable for severe weather to develop. It’s a heads-up to stay alert and prepare to act quickly if conditions worsen. This could include a tornado watch, thunderstorm watch, or winter storm watch.
3. Weather Warning: A warning is the most serious alert, issued when severe weather is already occurring or imminent. This is the time to take action and follow safety protocols.
Severe Weather in Late Summer & Fall
While summer heatwaves and storms may be winding down, late summer and fall bring their own risks:
- Tornadoes can still occur, especially in Ontario, the Prairies, and Quebec.
- Hurricanes and tropical storms can affect Atlantic Canada.
- Wind and hail storms become more frequent in early fall.
- Sudden drops in temperature may bring early snowfall and icy roads.
How to Stay Prepared
- Build a 72-hour emergency kit with food, water, a flashlight, batteries, a wind-up, solar or battery-operated radio, first aid supplies, and important documents.
- Secure outdoor furniture or equipment to prevent wind damage.
- Trim tree branches to reduce the risk of them falling and causing damage during storms.
- Create a family emergency plan and know your evacuation routes.
- Review your home insurance policy to ensure you're covered for wind, water, and storm damage.
