The change in the frequency of flooding and in the occurrence of flooding is sometimes due to development. Our communities really like to develop flood plains because that's the most desirable property and people want lakefronts or riverfronts for their homes.
It's also the change in the nature of storms. Storms cluster much more now than they used to. We get more multiple-day storms, greater storm intensities, greater rainfall intensities and now, in some cases, more rain on snow, depending on the elevation. All these are working together to make those changes to our flood regimes in Canada.
We now even have glacier melt causing floods. The peak flood in Whitehorse, Yukon, which occurred in 2021, was started by the heat dome that occurred that year. It was the Llewellyn Glacier and other snowpacks in the mountains above Whitehorse melting away at a rapid pace. We've never seen this before. This is what we have now.
