MANITOBA: Thunderstorm Forecast for Monday, June 5, 2023

Isolated pop-up thunderstorms are possible in Western Manitoba along the Saskatchewan border on Monday. These storms are expected to remain non-severe, but the environment is favourable for the development of funnel clouds and maybe even a landspout tornado.

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.
