Strong winds wreaked havoc across Alberta, causing significant disruptions and damage. Gusts reached speeds of up to 121 kilometers per hour on Sunday, impacting various communities across the province.
Severe Weather Impact in Alberta
The strongest winds were recorded in Two Hills, approximately 90 minutes east of Edmonton. Other areas, including Swan Hills, experienced serious structural damage. At the Swan Hills School, high winds ripped sections off the roof and damaged the underlying trusses. As a result, the Pembina Hills School Division closed the K-12 institution and transitioned its 200 students to online learning until a thorough structural assessment is completed.
Extent of Damage
The chaos caused by the winds included:
- Downed trees and branches.
- Flipped semi-trailers.
- Shingles and entire roofs torn off buildings.
Environment Canada issued wind warnings spanning from the Alberta-U.S. boundary to Fort McMurray, and parts of southwestern Saskatchewan. According to scientist Christy Climenhaga, the extreme winds formed as a low-pressure system swept through the region, bringing blustery conditions and light snowfall to certain areas.
High Wind Speeds Recorded
Many locations across Alberta recorded wind gusts exceeding 100 km/h. Notable speeds included:
- Waterton Lakes: 116 km/h
- Slave Lake: 109 km/h
- Medicine Hat and Vegreville: 107 km/h
- Lethbridge and Peace River: 100 km/h
Climenhaga emphasized the significance of such widespread and sustained wind events. Traditional tracking methods often struggle due to the variable nature of winds linked to different weather phenomena.
Power Outages and Safety Warnings
The powerful winds also resulted in widespread power outages. Approximately 8,400 homes were reported without electricity in Edmonton as of 1 p.m. that day. Fortis Alberta confirmed that outages affected around 8,000 residents at various times throughout the day.
Residents were advised to maintain a distance of at least 10 meters from downed power lines and damaged electrical equipment. Additionally, snow compounded the risks in southern Alberta, leading to reduced visibility and dangerous driving conditions on major highways.
As Alberta recovers from the chaos caused by these strong winds, Environment Canada warned that a similar wind system could develop later in the week, potentially affecting southern Alberta more acutely.
