Friday's storm shattered rainfall records in Montreal and across Quebec

While municipalities across Quebec continue to survey the damage caused by Friday's rainstorm, is is clear that the amount of rain that fell on Montreal shattered the record for percipitation accumulation in a single day.

It is the second top five daily rain total recorded in 2024.

Environment and Climate Change Canada (ECCC) said that at 153.8 millimetres, Friday's rain broke the Montreal daily record set in November 1996 by over 60 millimetres.

Here are the top five single-day rain accumulation records for Montreal:

1. 153.8 mm - Aug. 9, 2024
2. 93.5 mm - Nov. 8, 1996
3. 81.9 mm - Sept. 14, 1979
4. 80.5 mm - Oct. 6, 1995
5. 79.2 mm - July 10, 2024

ECCC began tabulating rainfail levels in 1942.
