Alberta: Thunderstorm Forecast for Tuesday, May 23, 2023

Pop-up non-severe thunderstorms are possible on Tuesday afternoon and evening to the northwest of Edmonton. This includes Whitecourt, Edson, Westlock, Slave Lake and High Prairie. While these storms will be non-severe, there is the potential for funnel clouds and maybe even a landspout.

Landspout: A landspout is a type of tornado that forms under a weak thunderstorm. Unlike traditional tornadoes, which develop from supercell thunderstorms and are associated with a rotating updraft called a mesocyclone, landspouts form from non-supercell storms and do not have a mesocyclone. These tornadoes are generally weaker and shorter-lived than their supercell counterparts but can still pose a threat to property and life, with wind speeds occasionally reaching up to 160 km/h.
