Northerly winds increase Thursday and redistribute storm snow into fresh wind slabs. Seek out sheltered terrain where snow has not been wind affected to find the best riding.

Avalanche Summary
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.
Snowpack Summary
20-35 cm of settling snow at alpine and treeline overlies old wind slabs in wind-exposed areas. 30-50 cm of snow covers a thick supportive crust found below 2000 m.
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.
Weather Summary
Wednesday Night
Partly cloudy with clear periods. Northwesterly ridge top winds 15 km/h. 1500m temperature low of -2C. The above freezing layer is present from 1500 - 2500 m tonight.

Overnight, cloudy with scattered flurries, 5-10 cm accumulation.

Terrain and Travel Advice
- Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
- Wind slabs are most reactive during their formation.
- Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
Problems
Wind Slabs
Up to 35 cm of very light unconsolidated storm snow is settling with elevated freezing levels and being redistributed by northerly winds. Watch for newly formed reactive wind slabs as you transition into wind-affected terrain.
Aspects: North East, East, South East, South, South West.
