Chinook winds have been raging in all elevation zones Thursday with intense wind transport of now occurring.  Look for windslabs to become increasingly sensitive to human triggering in the Alpine over the next few days.

    30-40cm thick windslabs are being encountered on north to southeast aspects at treeline and above. The stiffness of these slabs will have increased with the extreme winds at higher elevations. Expect larger propagation if hard slabs are triggered.

Confidence

Good
