We haven't received any reports of recent avalanche activity.

Please consider posting a MIN if you head into the backcountry.

Around 10 to 20 cm of snow accumulated since the start of the weekend. Strong southwest wind likely formed deeper and touchier slabs in lee terrain features.

Around 30 to 60 cm of snow may overly surface hoar and/or faceted grains and a hard melt-freeze crust from mid-November. Weak faceted grains may extend to the base of the snowpack, particularly in areas where the snowpack is thin.

Snow depths at treeline vary from about 50 to 100 cm and decrease rapidly at lower elevations.

Monday Night
Mostly cloudy. 2 to 5 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -2 °C. Freezing level 1700 m.

Tuesday
Mostly sunny. 30 km/h west ridgetop wind. Treeline temperature -4 °C. Freezing level 1300 m.

Wednesday
Cloudy. 10 to 20 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level rising to 2000 m.

Thursday
Cloudy. 5 to 15 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1400 m.

No recent avalanches have been reported, but observations are very limited in this region.

If you're heading out into the backcountry, please consider sharing your observations on the MIN.

30 to 45 mm of rain has fallen at lower elevations, while heavy wet snow may have accumulated at upper elevations. Exposed terrain has been highly wind-affected by southwesterly winds.

This builds upon previous storm slabs, which currently overlie older layers and a thick melt-freeze crust down 50 to 60 cm.

Total snowpack depths range from around 80 to 150 cm deep at treeline, and diminish rapidly at lower elevations.

Monday Night
Cloudy. 15 to 25 mm of rain or wet snow at upper elevations. 60 km/h southwest ridgetop wind. Treeline temperature +2 °C. Freezing level 2000 m lowering to 1500 m.

Tuesday
Cloudy. 5 to 15 mm of rain expected late afternoon. 50 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1600 m rising to 2200 m at night.

Wednesday
Cloudy. 10 mm of rain or wet snow at upper elevations. 50 km/h southwest ridgetop wind. Treeline temperature +1 °C. Freezing level 1800 m.

Thursday
Mostly cloudy. 50 km/h southwest ridgetop wind. Treeline temperature +1 °C. Freezing level 1800 m.

Many storm and wind slabs were triggered naturally, by riders, and by explosives on the weekend. They ranged from 20 to 80 cm deep, with the deeper avalanches likely failing on the weak layers described in the Snowpack Summary.

Looking forward, human-triggered avalanches remain very likely on Tuesday as the snowpack remains stressed from all the recent snow load.

Upwards of 80 cm of snow has accumulated since the start of the weekend, accompanied with strong southwest wind. A warming trend will increase slab properties.

All this snow is loading a weak surface hoar layer and/or weak faceted snow found 50 to 100 cm deep. Surface hoar is most likely in tree openings sheltered from the wind whereas faceted snow may be found in wind-exposed terrain into the alpine. Below this is a hard melt-freeze crust that formed mid-November.

Average treeline snow depths range from 90 to 140 cm, which tapers quickly at lower elevations.

Monday Night

Cloudy. 15 to 30 cm of snow with local amounts up to 50 cm possible. 50 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1600 m.

Tuesday

Mix of sun and clouds. 30 km/h west ridgetop wind. Treeline temperature -4 °C. Freezing level 1500 m.

Wednesday

Cloudy. 15 to 30 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level rising to 1800 m.

Thursday

Mostly cloudy. 5 to 15 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1500 m.
