Calgary sits on Canada’s Prairies, where a dry continental climate means annual precipitation is modest, but spring snowmelt combined with rain can raise rivers quickly, and summer brings the risk of intense, fast-moving thunderstorms.
At the confluence of the Bow and Elbow rivers, the city suffered one of Canada’s costliest natural disasters during the 2013 Alberta floods. Because the region’s flat terrain and clay-rich soil drain slowly, a heavy spring or summer storm on already-saturated ground can produce flooding well out of proportion to the region’s usual dry conditions, making radar useful for tracking storm cells across the open landscape.
