Calgary is bracing for significant rainfall over the next 24 hours, but city officials are sounding an optimistic note: major flooding is unlikely, thanks to a decade of strategic infrastructure improvements implemented since the devastating 2013 flood.
The City of Calgary released a statement Monday confirming that weather conditions are tracking "largely as forecasted," with between 40 and 70 millimetres of rain expected to fall across Calgary and the Bow and Elbow River catchments through Tuesday. While the rainfall is substantial, the city's enhanced reservoir management and upgraded flood defence systems have reduced the potential for catastrophic damage by more than 70 per cent compared to what Calgarians experienced in 2013.
"The infrastructure investments and water management strategies we've implemented since 2013 have fundamentally changed our flood resilience," a city spokesperson confirmed.
Environment Canada meteorologist Christy Climenhaga provided an update Monday, describing conditions across Alberta as "cats and dogs"—a colloquial reference to heavy downpours driven by a low-pressure system pulling moisture into the province. A yellow rainfall advisory remains in effect for Calgary.
Rain Distribution Varies Across the Region
As is typical for Alberta weather, rainfall is not distributing evenly across the city. Climenhaga noted significant variation, with the airport recording 27.8 millimetres over the past 48 hours, while the Springbank area measured 42 millimetres. Further south toward Staveley, some areas have already received approximately 100 millimetres.
"There's a lot of variation through the city, as you often see," Climenhaga said, highlighting the unpredictable nature of Alberta's precipitation patterns.
Relief is expected by Wednesday as the weather system moves through the province, though rainfall will continue through much of Monday night and into early Tuesday.
