Avalanche Summary
A few small (size 1) wet loose avalanches were observed out of steep and rocky terrain on Wednesday. Riders also triggered some small (size 1) wind slabs on Tuesday.
Looking forward, small wet loose avalanches could be triggered during periods of sunny skies but they are unlikely to impact riders. Use plenty of caution along alpine ridges, where cornices may be large.
Snowpack Summary
Around 5 to 10 cm of dry snow overlies a hard melt-freeze crust. The snow may moisten on sun-exposed slopes during sunny conditions and freeze into a melt-freeze crust overnight.
The remainder of the snowpack is strong with varying hard snow layers and bonded melt-freeze crusts. Cornices are large along many alpine ridges.
