Wind slab remains the primary concern in this region.
Head to sheltered terrain for the best riding conditions.

Moderate
Avalanche Summary
Wind loaded features remained triggerable by riders on Sunday, to size 1. While explosives produced up to size 2 slabs.
We expect reactivity to decrease over the next few days. Observations are limited, please submit to the MIN network if you head into the backcountry.
Snowpack Summary
Surfaces at higher elevations are heavily wind effected, with wind loading on east facing slopes and west facing slopes likely scoured. These slabs may sit over a crust, hard wind affected surfaces or surface facets (weak crystals).
A melt freeze crust exists near the base of the snowpack, reports suggest it is currently not a problem for the region.
Treeline snow depths are typically 50 to 80 cm, with deeper wind-loaded pockets in the alpine.

Terrain and Travel Advice
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
- Expect slab conditions to change drastically as you move into wind-exposed terrain.
- Make observations and continually assess conditions as you travel.
Problems
Wind Slabs
Wind slabs remain reactive to human triggers. Fresh slabs will form where snow is available for transport.
Aspects: North, North East, East, South East.
