Given the short daylight hours at this time of year, start your trip early and plan to be back at the trailhead before sunset.

Weather Forecast

Light flurries accompanied by light winds will be the weather today. Freezing levels may rise as high as 1200m, but then lower to valley bottom for Wednesday morning. Generally cloudy for the next few days afterwards, without any significant snow, sun, or wind input to talk about.

Snowpack Summary

The overnight dusting we received covered up the variable snow surfaces from the holidays. There was widespread surface hoar from 1700m to ridgetop, thin variable slab in wind-exposed alpine areas, and thin sun crusts on steep solar aspects. Lower elevation and wind-protected areas have 10-15cm of low density faceted snow on a well settled base.

Avalanche Summary

Several loose size 1 to 2 avalanches were observed east of Rogers Pass in the highway corridor, all off of Mt Tupper and Mt Macdonald. Start zones were steep, rocky, unskiable terrain and the debris stopped high on the fans, so they were not travelling too far.

Confidence

Avalanche Problems

Loose Dry

Loose sluffs can be expected in steep rocky terrain. Gullies can focus the force of moving snow, causing these innocent-looking masses to pack a punch.
Be cautious of sluffing in steep terrain.Be aware of party members below you that may be exposed to your sluffs.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
