Weather Forecast

Expect another 10-20cm by Wednesday afternoon with moderate SW winds. The day will start out around -8c and drop down to -18c.

Avalanche Summary

There is evidence of several size 2 and one size 3 that occurred during the last 24hrs. Skiers on Tuesday reported a skier triggered slab in the Tryst chutes.

Snowpack Summary

Another 15cm of 24hour snow, bringing the storm snow to 50-60cm. At treeline and below, the storm snow is bonding relatively well to the hard wind slab underneath. On Tuesday, in open areas at treeline and above, the winds were intense and have started to slab up the top 30cm+ and is reactive to skier traffic. Expect to find wind slabs up to 100cm thick, especially in lee features and cross loaded gullies. Open areas at treeline and above will need to be approached with caution. Watch for cracking around your skis.

Terrain and Travel

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Be careful as you transition into wind affected terrain.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Shooting cracks, whumphs and recent avalanches are strong indicators of an unstable snowpack.
