New QC tornadoes: June 16th
Careful and thorough NTP investigation has led to the confirmation of six new tornadoes in Quebec from supercell thunderstorms on June 16th. These storms occurred more than 250 km north of Montreal and moved toward the NE toward Lac Saint-Jean. Two of the tornadoes were assigned an EF2 rating while the rest were assigned EF1, based on analysis of high-resolution satellite imagery. Note that there were also two weak tornadoes on this day in Ontario.
Below are the events summaries in chronological order, followed by some event imagery.
