Overview
- Environment and Climate Change Canada activated yellow, orange and red levels across Warnings, Advisories and Watches to show severity and expected risk.
- Meteorologists will use an Alert Colour Matrix with new Impact Guides that combine weather models, real-time observations and forecast confidence to describe likely effects on people, property and communities.
- Yellow denotes hazardous conditions with moderate, localized or short-term impacts, orange signals likely significant and possibly multi-day impacts, and red flags very dangerous, potentially life-threatening events with extensive disruption.
- Updated alerts are available now on Canada.ca/Weather and through the free WeatherCAN mobile app on Android and iOS.
- The rollout aligns with World Meteorological Organization practices as part of a broader public weather program modernization, with further forecasting and alerting improvements slated over the coming year.
