After the storm: Record-breaking rainfall and a possible 2nd tornado near Montreal

A powerful storm that swept through southwestern Quebec on Thursday produced record rainfall, flash flooding, and at least one tornado on the territory -- possibly two. Environment Canada recorded 38.6 millimetres of rain in Montreal alone, surpassing the 1997 record of 34 mm.

A powerful storm that swept through southwestern Quebec on Thursday produced record rainfall, flash flooding, and at least one tornado on the territory -- possibly two.

Environment Canada recorded 38.6 millimetres of rain in Montreal alone, according to its online database, surpassing the 1997 record of 34 mm.

At least one tornado was recorded in Quebec. The funnel clouds touched ground Thursday afternoon near the Mirabel airport, about 50 kilometres northeast of Montreal.

Environment Canada is also investigating a second possible tornado, this one southwest of Montreal in the Salaberry-de-Valleyfield area.

No injuries or damage were reported in either case.

Montreal was under a tornado warning for part of the day, something experts described as exceedingly rare -- but the warning was downgraded to a tornado "watch" by the early evening, with no twisters in sight (just lots and lots of lightning, thunder and rain).

The same can't be for Ottawa, however, where a tornado damaged over 100 homes in the south-end suburb of Barrhaven. No injuries were reported.
