Up to 10cm of new snow is forecast to fall over the weekend along with strong SW winds.

Summary

Confidence

Good - Timing, track, or intensity of incoming weather system is uncertain

Weather Forecast

Dribs and drabs of new snow over the next 24hrs but not enough to really change the current avalanche danger. Winds are forecast to become strong out of the SW as the chinook approaches

Avalanche Summary

No new avalanche activty.

Snowpack Summary

5-10cm recent HST overlying a variety of snow surfaces from hardslabs, facets and ground. Snowpack is weak and shallow in most areas. The 1027 melt freeze crust is found but it is very spotty in many areas.

Problems

Persistent Slabs

Pockets of wind slabs can still be found in the Alpine and selected areas at Treeline. Any avalanche that is triggered will likely fail on the basal October crust (or the ground) and involve the entire winters snowpack.

Be aware of thin areas that may propogate to deeper instabilites.>Early season hazards such as rocks, trees and stumps are still visible.>
