First QC tornado of 2024 at Rigaud
An NTP investigation has confirmed the first QC tornado of 2024 in the Rigaud area - just east of the ON border.
The tornado was initially confirmed based on video/photos plus radar. An NTP severe storm survey team began a ground / drone investigation starting the next afternoon and was able to document damage to a house, barns and farm silos over a 14.3 km path. The damage was consistent with a maximum wind speed of 155 km/h, which is the middle of the range for EF1 on the EF scale.
The event summary is included below, along with maps, survey photos and related radar imagery. The event can also be plotted using the NTP Dashboard here.
