MANITOBA: Thunderstorm Forecast for Tuesday, May 30, 2023

Isolated pop-up storms are possible across much of Southern Manitoba on Tuesday. A few of these storms could become severe with nickel-sized hail and 90 km/h wind gusts in Southeastern Manitoba and parts of South-central along the American border. Another concern 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.
