Six tornadoes in SK/MB on June 12
NTP investigation has concluded that six tornadoes occurred in SK and MB on June 12. The first tornado hit Salcoats in southeast SK early in the afternoon, while a further five tornadoes developed between Rivers and St. Alphonse in southweste MB during the late afternoon and early evening. The EF scale ratings were assessed at between EF0-Default (no damage) to EF1. A downburst was also identified at the end of one of the tornadoes near Glenboro.
Note that these are the first tornadoes of the season for both SK and MB - a somewhat late start in those provinces.
Event summaries for each tornado and downburst are provided below, along with maps and damage photos. The events can also be plotted using the NTP Dashboard here.
