    Recent storm snow will have increase the chance of storm slab avalanches.

    New snow and strong southwesterly winds may have formed fresh wind slabs in the alpine and at treeline. Watch for typical wind loading around ridgelines and convexities and be aware of mid-slope cross loaded features.

    Deeper weak layers have not produced avalanches for sometime, but may be possible to trigger with step down avalanches.

Avalanche Summary

There have been a number of avalanches observed in our region yesterday. These were caused by storm slabs and ranged in size 1 to 2. They were caused by skiers triggering them accidentally and remotely. A party also reported that they could hear a number of avalanches from Keith's Hut on Tuesday.

Please continue to share any observations or photos on the Mountain Information Network.

Snowpack Summary

Up to 50 cm of recent storm snow is now sitting in sheltered areas. At higher elevations and in exposed areas, this new snow has been redistributed by southerly winds.

Fresh wind slabs will be found laying onto older wind slabs while in sheltered areas, storm snow will be resting on 15 to 25 cm of soft snow. A crust may be found in the upper snowpack on steep solar aspects and below 1800 m.

A weak layer of faceted snow or decomposing crust can be found buried 70 to 100 cm deep.

Generally, the snowpack in this region is weak and shallow with sugary snow near the base. Snowpack depths around treeline range between 150 to 250 cm.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Be carefull around freshly wind loaded features.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
