Canmore, Alberta is expected to see temperatures drop to -20°C on the nights of February 17 and February 18, 2026. This forecasted cold is nearly double the typical seasonal low of -11°C for the middle of February. According to Environment Canada, the extreme dip in temperature follows several days of predicted snowfall.
The Town of Canmore and utility provider EPCOR are advising residents to take steps to prevent outdoor water lines from freezing. Homeowners can help protect their pipes by leaving a small trickle of water running if their service lines are prone to freezing. This precaution is especially important in older sections of the community where pipes may not be buried deep enough to avoid the frost.
The Government of Canada warns that exposed skin can freeze in as little as 10 to 30 minutes during these conditions. People working or travelling at night are encouraged to cover up to avoid frostbite. The sudden change from warmer weather earlier in the week may also lead to icy road conditions as moisture on the ground freezes quickly.
Regional forecasts note that heavy snow forecast for February 16 and February 17, 2026, combined with the deep freeze, may increase the risk of avalanches in the Bow Valley. Residents and visitors planning to be outdoors should remain cautious of changing conditions in the surrounding mountains. The cold weather is expected to continue through the early part of the week.
