Fair - Due to the number of field observations

Weather Forecast

Light flurries and a mix on sun and cloud are expected for the forecast period. Freezing levels are expected to sit between 1200m and 1400m. Winds should remain generally moderate from the southwest.

Avalanche Summary

I'm sure human wind slab triggering will be possible over the weekend. Check out the blue dot on our Forecast Region Overview Map for details on a recently triggered wind slab avalanche.

Snowpack Summary

New snow has landed on recently formed wind slabs and wind-scoured surfaces. Weaknesses buried in the upper snowpack include hard crusts, surface hoar, and/or surface facets. At the base of the snowpack, weak facets may be found. Cornices are large and potentially fragile. Below treeline, the snow appears to be in a spring melt-freeze cycle.
