Alberta: Thunderstorm Forecast for Monday, June 19, 2023
/
Pop-up thunderstorms are expected around Edmonton and to the northeast during the afternoon and evening on Monday. These storms are expected to remain non-severe. However, the environment is favourable for funnel cloud development. In rare cases, funnel clouds can touch down and become a landspout tornado. This landspout risk stretches from Leduc through Camrose and into Cold Lake.
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.
