Points saillants

Dial back your terrain choices as the storm intensifies. Snowfall and moderate wind will build larger and more reactive wind slabs in the afternoon.

    The wind slab problem will increase throughout the day as snow is accumulating. Wind slabs may be very reactive to rider traffic due to poor bonding with the underlying crust.

Confidence

Moderate

  • We are uncertain due to the timing, track, and intensity of the incoming weather system.

Avalanche Summary

No new avalanches have been observed or reported.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

By Wednesday evening, we may receive around 15 cm of new snow, which will overlay a widespread melt-freeze crust present on all aspects and at all elevations. Deeper deposits may be found on northerly aspects, while westerly aspects are mostly bare.

The remainder of the upper snowpack is composed of multiple crusts and moist snow. The mid and lower snowpack are well settled.

At mid-elevations, the average snowpack depth is around 110 cm.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Wind slabs are most reactive during their formation.
  • Carefully evaluate steep lines for wind slabs.
