Alberta Reels from Powerful Windstorm & Widespread Power Outages

A powerful windstorm swept across Alberta on Sunday, unleashing gusts of up to 121 kilometres per hour. The extreme weather event resulted in widespread damage, including downed trees, structural damage to buildings, and significant power outages affecting thousands of residents. While Chilliwack wasn’t directly impacted, the event serves as a reminder of the potential for severe weather across Western Canada.

Devastating Wind Gusts & Damage Reports

The storm’s fury was particularly evident in Swan Hills, approximately 200 kilometres northwest of Edmonton, where the school sustained significant roof damage. The Pembina Hills School Division promptly closed the K-12 school and initiated a structural assessment to ensure student and staff safety. Students will temporarily transition to online learning during the assessment period.

Environment Canada had issued wind warnings for most of Alberta, extending to parts of southwestern Saskatchewan. Scientist Christy Climenhaga explained that the province experienced a low-pressure system and a cold front, bringing exceptionally gusty winds and snowfall to various regions.

The strongest recorded wind gust in Alberta occurred in Two Hills, reaching a peak of 121 km/h. Numerous other communities experienced winds exceeding 100 km/h, including Waterton Lakes National Park (116 km/h), Slave Lake (109 km/h), Medicine Hat (107 km/h), and Vegreville (107 km/h). Even geographically distant cities like Lethbridge and Peace River both registered winds of 100 km/h.

Power Outages & Safety Concerns

The storm’s impact on Alberta’s power grid was substantial. At 1 p.m. on Sunday, EPCOR reported approximately 8,400 homes in Edmonton without power. Fortis Alberta reported similar outages, with around 8,000 residents affected throughout the day. ATCO also reported power outages in northwestern Alberta.

Authorities urged residents to exercise extreme caution, particularly staying at least 10 metres away from downed power lines and avoiding any damaged electrical equipment. Reports surfaced of debris being blown into yards, including an entire metal shed landing in a West Meadowlark yard.

Snowfall & Travel Disruptions

Adding to the challenges, southern Alberta experienced significant snowfall, with accumulations of up to 20 cm expected in areas like Calgary, Banff, Strathmore, Waterton Lakes, and Vulcan. The RCMP issued a warning near Airdrie regarding limited visibility on major highways, including the QEII, due to strong winds and blowing snow, responding to several crashes.

Looking Ahead: Potential for Further Weather Events

Environment Canada anticipates a similar weather system may return later this week, though it is expected to be more active in southern Alberta. Residents are encouraged to stay informed and prepared for potential further disruptions.
