Look for signs of instability and assess for wind slab as you move through terrain.
Wind slabs remain the primary concern.
The likelihood of avalanches could increase if the sun comes out.

Avalanche Summary
No new avalanches have been reported in this region.
Numerous large to very large natural and human triggered persistent slab avalanches continue to be reported in the neighboring region . Some have run full path to valley bottoms. Many of the human triggered avalanches have been reported as remotely triggered (from a distance). This speaks to the sensitivity of the persistent slab.
Snowpack Summary
A variety of surfaces can be found including a new crust on sun exposed terrain and wind effect in the alpine.
A thick and hard widespread crust that formed in early February is buried about 40 to 70 cm deep. This crust may have a layer of facets above it.
The snowpack below this crust is generally not concerning.
Weather Summary
Saturday Night
A mix of clear skies and cloud with up to 5 cm of new snow. 15 to 30 km/h southeast alpine wind switching to southwest. Treeline temperature -10°C.
Sunday
A mix of sun and cloud with 2 to 4 cm of new snow. 5 to 25 km/h south alpine wind. Treeline temperature -9°C.
Monday
A mix of sun and cloud with trace amounts of new snow. 10 to 25 km/h southwest alpine wind. Treeline temperature -8°C.
Tuesday
Mostly sunny. 5 to 20 km/h northwest alpine wind. Treeline temperature -13°C.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
- Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.
- Remote triggering is a concern, watch out for adjacent and overhead slopes.
Problems
Wind Slabs
Wind slabs may remain triggerable to riders. Assess for slabs in lee terrain features prior to committing.
