    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.

Good

Weather Forecast

Continued warm and windy for another day.  Daytime highs approaching zero degrees with some concern for daytime heating issues on steep southerly aspects during sunny periods.  No new precip in the forecasts for the next few days.
