If an orange weather warning appears for your community today, from southern Ontario to the Maritimes, expect conditions serious enough to disrupt travel and daily routines. Environment Canada issues these alerts when weather poses a moderate risk to life or property, meaning you should reconsider non-essential travel and monitor local forecasts closely.
What does an orange weather warning mean in Canada?
An orange warning marks a moderate hazard, bridging the gap between a yellow warning (minor risk) and a red alert (extreme danger). For snowfall in particular, this level indicates significant accumulations within a short period—often 15 centimetres or more in 12 hours—making roads hazardous and reducing visibility. When you see an orange warning for your area, conditions will actively require you to adapt your schedule and driving habits.
How should you respond to an orange warning today?
If an orange weather warning is active for southern Ontario or your region today, postpone unnecessary trips and secure loose outdoor items. Ensure your emergency kit is ready and your home is stocked for 24 to 48 hours, as heavy snow or ice can bring down trees and power lines. Stay tuned to local radio or our Canada weather hub for updates as the situation evolves.
Is an orange weather warning worse than a yellow warning?
Yes. A yellow warning means watch for potential changes, while an orange warning means a moderate hazard is imminent or already happening. You should actively change your plans—especially around travel—to stay safe during an orange alert.
What does an orange warning mean for snowfall?
An orange snowfall warning signals heavy accumulation expected within 12 hours, typically 15 centimetres or more. Roads will become difficult to travel, and visibility may drop suddenly. Plan to stay off the roads until the storm weakens and crews can clear the routes.
