It is important to be disciplined with terrain choices. Many slopes look quite attractive with the recent snow, but the Feb 10th layer still needs time to heal. Human-triggering remains likely.

Problems

Persistent Slabs

Naturally triggered avalanche activity has subsided, but human triggering remains touchy. The Feb 10 persistent weak layer will be a problem for some time and is now buried 35 and 70cm. Whumpfing and cracking have been observed in recent days.

Use caution in lee areas in the alpine. Recent wind loading have created wind slabs.>Be cautious as you transition into wind affected terrain.>Avoid steep, open slopes.>
