Environment Canada cancelled a tornado warning for the County of Warner on Thursday evening but maintained an active thunderstorm warning that includes Lethbridge as the region remains at risk of severe storms.
Current alert and risks
The national weather service says atmospheric conditions across southern Alberta remain conducive to storms capable of producing strong wind gusts, large hail and heavy rainfall. While the immediate tornado threat for the Warner area has passed, the broader threat of severe thunderstorms — and the damage they can cause — persists.
"Be prepared for severe weather."
Precautions for residents and services
Environment Canada advises residents to move indoors to a basement or an interior room if severe weather approaches and to stay away from windows to reduce risk from flying debris and hail. Municipal services in Lethbridge may need to monitor localized flooding, power outages and downed trees if storms bring intense rain or wind.
- Shelter: Go to a basement or interior room away from windows.
- Avoid hazards: Stay clear of debris, and avoid driving through flooded roadways.
- Stay informed: Monitor updates from Environment Canada and local authorities for changing warnings.
Local impacts and context
Lethbridge residents should expect sudden changes in conditions when storms move through: severe downpours can create brief but intense flooding on low-lying streets and underpasses, while large hail can damage vehicles and roofs. Utility crews and road maintenance teams often respond quickly after such events; however, restoration of power or removal of fallen trees can take time depending on the scope of damage across the region.
| Area | Alert | Status |
|---|---|---|
| County of Warner | Tornado warning | Cancelled |
| Lethbridge | Thunderstorm warning | In effect |
Residents should keep a battery-powered radio, charged mobile devices and emergency supplies available in case severe weather leads to temporary outages. For the latest advisories and any evacuation notices, follow Environment Canada bulletins and updates from City of Lethbridge emergency services.
