Avalanche Canada
Moderate your storm stoke! Early season hazards such as rocks and snaggy trees are plentiful below treeline, and lurk just below the surface at treeline and above.
We've reached threshold for avalanches to occur at treeline and above- be sure to assess for instability with the 55+cm of recent storm snow!

Moderate
Avalanche Summary
Several avalanches were observed today in the highway corridor from very steep terrain in the alpine (Mt Macdonald and Tupper). These avalanches were large enough to bury, injure or kill a rider and ran down into below treeline elevations.
Snowpack Summary
Rogers Pass received ~35cm of new snow in the last 24 hours! This brings our height of snow up to 1-1.2m at treeline elevations. Moderate to strong SW'ly winds have been redistributing the new low density snow, which may leave some areas scoured and other areas in lees building slabs. Below treeline remains below threshold for avalanches with 50cm on the ground at Rogers Pass (1300m).
Weather Summary
The warm, stormy period will come to an end as an artic ridge of high pressure moves into the southern half of the province. Expect an alpine high of -13°C with moderate east winds. Monday
Bundle up! The arctic ridge will be firmly in place by Monday with temperatures hovering around -20°C with moderate east winds. This ridge looks like it's here to stay into the foreseeable future this week.
Terrain and Travel Advice
- Make conservative terrain choices and avoid overhead hazard.
- Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
