The storm caused damage to properties and uprooted trees, leaving many without power. Fortis Alberta reported power outages in Newell and Vulcan counties. Alberta 511 also confirmed that Highway 1 was temporarily closed between Brooks and Bassano due to collisions and fallen power lines.

Near Brooks, metal power lines were flattened, trees and poles snapped, and irrigation pivots sustained damage.

As of Thursday morning, there have been no confirmed tornadoes associated with this storm, but peak wind gusts reached nearly 150 km/h. The Northern Tornadoes Project (NTP) and Northern Hail Project (NHP) will investigate this event further.
