Central and southern Alberta are under yellow-level rainfall warnings as heavy rain continues, with totals since Saturday reaching over 135 mm in some areas. Environment and Climate Change Canada (ECCC) reported that rainfall amounts varied, with most areas receiving between 40 to 120 mm. A flood watch is currently in effect for the Bow River near Lake Louise due to increased water flow, while high streamflow advisories are in place across the region. The heavy rain, combined with strong winds of 40 to 60 km/h in Calgary, poses risks of falling trees on saturated ground. In southeastern British Columbia, a special weather statement warns of flooding and landslides, with expected rainfall amounts of 60 to 80 mm in certain areas. Cooler temperatures have resulted in snow accumulation in higher elevations, which helps maintain the winter snowpack. As rain tapers off, Calgary may see an additional 5 to 10 mm of rain on Tuesday, with a return to more seasonal temperatures expected by Thursday.
