Environment Canada Issues Tornado Warning Manitoba for Southern Communities
Environment Canada issued a tornado warning Manitoba Tuesday for parts of southern Manitoba after meteorologists tracked a severe thunderstorm that was possibly producing a tornado. The warning covered multiple rural municipalities and nearby communities, with dangerous weather moving through the region.
At 4:57 PM CST, meteorologists were tracking the storm and said it could produce damaging winds, large hail and locally intense rainfall. Forecasters also said one or two tornadoes were possible, and they described the situation as dangerous and potentially life-threatening.
Southern Manitoba warning areas
The warning included the R.M. of Thompson, including Miami, Rosebank and Deerwood; the R.M. of West Interlake, including Eriksdale and Ashern; the R.M. of Grahamdale, including Gypsumville, Moosehorn and Camper; and the R.M. of Dufferin, including Carman, Roseisle and Homewood. Locations in the path included Miami, Graysville, Carman and Homewood.
Those communities were in the path as thunderstorms were expected to initiate in the U.S. before moving into southwestern Manitoba during the afternoon, then tracking northeast toward the Interlake and eastern regions by early evening. Brandon faced the greatest storm risk from 3 to 6 p.m. local time.
Storm setup across Manitoba
Environment Canada said thunderstorms were expected Tuesday as a shortwave trough moved across southern Manitoba and North Dakota. Wind shear and steep lapse rates were expected to support supercell development, with large hail potentially toonie-sized or larger identified as the primary threat.
The same system was expected to organize into isolated storms before becoming widespread clusters by early evening. Thunderstorms were expected to reach Winnipeg after dinner and into the evening hours, after moving out of southwestern Manitoba and across the region.
Tuesday evening risk
For people in the warning area, the immediate concern was the track of the storm through rural municipalities and nearby communities already listed by forecasters. The combination of possible tornadoes, large hail and strong outflow wind gusts kept the warning focused on fast-changing conditions rather than a single hazard.
As the storm moved northeast, the most relevant next step for residents was to follow the warning area and the storm path already identified by meteorologists, especially in Miami, Graysville, Carman and Homewood.
