    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

Extreme winds (100km/hr +) are forecasted for the next 36hrs in the alpine. Treeline winds will be considerably less, but still in the range for slab development. The winds will be out of the west. The temps will still be warmer than usual, especially in the Bow Valley and front range. No significant precip is forecasted until after the week-end.
