Canada has unveiled a new downfall alert system designed to make it easier for the public to understand and respond to extreme downfall events.
The action, led by Environment and Climate Change Canada, uses a simple colour-coded warning system to show the strictness of downfall risks, helping residents stay safe during storms, snow, or heavy downfall.
Three Colours, One Clear Message
The system uses three colours, yellow, orange, and red, to communicate the potential impact of incoming weather:
1/4 New: #Weather alerts—Warnings, Advisories, and Watches—are now colour-coded. Moving from yellow, to orange, to red as the potential risk increases.
Always read your alerts to be #WeatherReady.

- Yellow Alerts: These are the most common warnings. They indicate hazardous conditions that could cause minor damage or local disruptions. Think short travel delays or minor power outages.
- Orange Alerts: Issued when severe weather is expected to cause significant problems. This could include widespread flooding, road closures, or structural damage.
- Red Alerts: The rarest and most serious warnings. They indicate life-threatening conditions capable of causing extensive damage and disruption, such as major storms or ice events.
Why a New System Was Needed?
Canada has faced several extreme rainfall events in recent decades. Red cautions would have applied to the 1998 ice storm in Ontario and Quebec, the 2020 “snowmageddon” in St. John’s, Newfoundland, and the 2021 atmospheric swash in British Columbia.
By learning from these events, the government hopes the new extreme rainfall warning system will give clearer guidance for the public.
Practical Examples for Everyday Life
The government has shared examples of how these alerts will work in practice:
- Snowfall: A yellow warning may cause minor travel delays, while an orange alert could shut down roads for days.
- Rainfall: Yellow alerts indicate potential flooding in low-lying areas. Orange alerts signal major flooding, travel delays, and possible landslides. Red alerts, such as during the 2021 atmospheric rivers, warn of extreme flooding.
- Wind: Yellow warnings may mean broken branches and short outages, orange warnings indicate possible structural damage, and red warnings signal extensive property damage and prolonged power cuts.
Minister Highlights Importance of Clear Alerts
Julie Dabrusin, Minister of Environment and Climate Change, emphasised that clear and timely rainfall cautions are pivotal.
She said, “These improvements aim to help Canadians make informed decisions to safeguard themselves and their property.”
With extreme weather events on the rise, the government hopes the new system will make Canadians better prepared.
A Step Towards Safer Communities
The preface of this colour-enciphered Canadian rainfall alert system marks a significant step forward in public safety.
By offering easy-to-understand guidance on storms, cataracts, snow, and wind, the system ensures people can act instantly to cover themselves, their families, and their property.
