Avalanche Summary

There have been very few reports coming from the region in the past week. On Sunday, the main concern is lingering wind slabs in high elevation north facing terrain and the possibility of large overhanging cornices releasing with overall warm temperatures and the sun coming out over the coming days.

Snowpack Summary

A series of Pacific frontal systems have passed through the region in the latter half of last week accumulating 15-25cm of moist new snow tree line and above. In high elevation terrain, recent moderate southerly winds and new snowfall has formed wind slabs in leeward features. At lower elevations and on sun exposed slopes, there is likely moist or wet snow sitting on top of several well bonded crust layers in the upper snowpack.
