North Calgary sees biggest snowfall of the year, more possible this month
Calgary snowstorm drops up to 30 cm, causes 170+ collisions and hazardous roads
A narrow, intense snow band formed north of Calgary Wednesday afternoon. Below-freezing temperatures, along with sufficient moisture and instability from the Rockies, contributed to its development.
These types of localized snow events are challenging to predict because of their small size and complex dynamics.
The storm brought stark contrasts to Calgary, with heavy snowfall blanketing the city's north while the south remained relatively dry. Environment and Climate Change Canada (ECCC) recorded 17.8 cm of snow at YYC, making it the city's largest snow event of the year, and the most snowfall in a single day since Nov. 23, 2024.

The wintry weather caused significant disruptions, with Calgary police reporting over 170 collisions throughout the day.
Authorities urged drivers to avoid unnecessary travel, highlighting hazardous conditions on northern sections of Stoney Trail.
While spring is officially underway, Calgarians should remain prepared for further winter weather. March is typically Calgary’s snowiest month, averaging 23.8 cm of snowfall based on 1991-2020 data.
