MANITOBA: Thunderstorm Forecast for Wednesday, June 7, 2023

Isolated thunderstorm activity is expected across much of Southern Manitoba on Wednesday. It will be more concentrated in Southwestern Manitoba along with the Interlake region. Some of these storms could reach severe levels with 90+ km/h wind gusts and up to quarter-sized hail. The environment is also favourable for the development of 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.
