The alpine rating is Wind Slabs.
, the treeline rating is , and the below treeline rating is Known problems includeAssess for pockets of consolidated wind slabs near ridge features and high points. Head to areas sheltered from the recent wind for the best riding conditions.
Plenty of early season hazards, such as buried rocks and tree stumps still exist.

Avalanche Summary
No new avalanches have been reported in the past few days in the region.
Please continue to share any observations of photos on the Mountain Information Network!
Snowpack Summary
20-40 cm of snow received last week has been redistributed into isolated pockets of windslab in wind exposed terrain at higher elevations. In sheltered areas, with no recent wind effect, loose dry snow can still be found.
The mid and lower snowpack generally consists of sugary faceted, weak snow.
Snowpack depths are highly variable, ranging from 80-180 cm in the alpine. Below treeline the snowpack is thin and generally below the avalanche threshold, making it a challenge to access terrain in many areas without damaging your sled or skis.
Weather Summary
Monday Night
Mostly cloudy. No precipitation is expected. Light westerly winds in the lower alpine. A temperature inversion in the alpine with temperatures ranging from -5 to -15 C and colder at lower elevations.
Tuesday
Mostly cloudy, isolated flurries in the afternoon. Moderate westerly winds and temperature -5 to -10 C in the lower alpine.
WednesdayMostly cloudy with no new snow expected. Moderate westerly winds and temperature -5 to -10 C in the lower alpine.
ThursdayMostly cloudy with no new snow expected. Moderate westerly winds and temperature -5 to -15 C in the lower alpine.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Seek out sheltered terrain where new snow hasn't been wind-affected.
- Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
Problems
Wind Slabs
It is still possible that reactive wind slabs can be found in isolated, wind exposed terrain features (ridges and high points) at higher elevations on all aspects.
Aspects: All aspects.
