Figure 3.7: Annual number of heavy precipitation days projected for 2021-2050 in Canada, based on current GHG emission trends (RCP 8.5).

Blue areas correspond to areas with more than 10 days per year of extreme precipitation, while brown areas correspond to areas with less than 4 days per year of extreme precipitation. A Heavy Precipitation Day (HPD) is a day on which a total of at least 20 mm of rain or precipitation falls. Frozen precipitation is measured by its liquid equivalent: 20 cm of snow equals about 20 mm of precipitation.
