A massive Pacific low-pressure system is tearing across the British Columbia Interior into Alberta today. It is dragging severe winter weather back into the region just as Canada’s broader aviation network attempts to recover from a grueling 85-day national disruption crisis.
As of the morning of March 25, 2026, a sudden blast of snow following unseasonably warm temperatures triggered chaotic scenes across the city. The Calgary Police Service issued an urgent public advisory instructing motorists “not to travel” due to zero-visibility blowing snow and active road closures.
The localized travel hurdle is hitting hard. Major commuting arteries including Stoney Trail and Deerfoot Trail are heavily impacted. Between midnight and 8:00 a.m. local time, police recorded 14 separate collisions. Two of those crashes resulted in injuries.
Calgary International Airport confirmed multiple flight delays and cancellations. Crews scrambled to clear runways this morning. National aviation data from March 25 indicated that overall Canadian flight disruptions had finally dropped by 80 percent following a prolonged period of winter storms, Middle East crisis airspace cascades, and Air Canada maintenance groundings. YYC is now a localized chokepoint in an otherwise recovering national airspace.
Environment and Climate Change Canada expanded yellow-level snowfall and winter storm warnings across the province. Calgary is seeing localized bands of snow. Surrounding regions are bracing for 20 to 30 centimeters of accumulation. Up north, extreme wind chills are dropping to -40 degrees Celsius.
The backcountry is also taking a hit. The sudden dumping of fresh snow critically elevated mountain dangers. Avalanche Canada issued high-risk warnings for the areas directly west of Calgary.
