The region continues to see small amounts of overnight precipitation and northwesterly winds. Watch for newly formed reactive wind slabs as you transition into wind-affected terrain.
5-10 cm overnight brings this week's storm snow totals to 40 cm in the alpine. Strong northwesterly winds are redistributing available snow into fresh wind slabs in lees. Seek out sheltered terrain where you can avoid wind slabs and find great riding.
On Wednesday, we received a MIN report of a skier accidental avalanche from Nak Bowl. The avalanche happened when skiing over a convexity and likely released on a crust below the storm snow. A natural size 2.5 wind slab avalanche was also reported from Nak Peak area. This avalanche is suspected to have stepped down to deeper layers. Several loose avalanches were observed up to size 2 on south aspects from solar input and elevated freezing levels.
On Tuesday, several, size 1, natural loose dry avalanches were reported from within the storm snow.
Thank you for all the MINs, please continue to share any observations or photos on the Mountain Information Network.
30-40 cm of storm snow at alpine and treeline is being redistributed into deep pockets at higher elevations. Below 2000 m supportive crust is found 50 cm deep.
Generally, the snowpack is well-settled. Weak layers exist within the mid and lower snowpack but the thick crusts sitting above them make triggering avalanches on these layers unlikely.
Snowpack depths are roughly 150 cm at treeline and taper rapidly below 1500 m.
