Avalanche Summary
Several size 1 loose dry avalanches out of steep rocky terrain were reported yesterday as the sun poked out. One of these pulling a windslab resulting in a sz 1.5.
Early season reports have been very limited. Please consider helping forecasters and your backcountry community by submitting your observations to the Mountain Information Network.
Snowpack Summary
Up to 25 cm of recent storm snow has been redistributed by winds. This sits on old windslabs and a faceted midpack. There is a thin crust 20-30cm below the surface, as well as a notable 5-15 cm thick crust near the base of the snowpack, surrounded by facets above and below. Snow depth in the alpine is approximately 80 cm but varies greatly due to wind redistributing the snow. Snow amounts at treeline taper off quickly with elevation.
Weather Summary
Sunday
Cloudy with sunny periods and isolated flurries (trace amounts). High -9 °C with generally light ridge wind except for areas with strong gap winds that will weaken throughout the day. Freezing level at valley bottom.
Monday
Cloudy with sunny periods and isolated flurries (trace amounts). Low of -12 °C and a high of -8 °C with winds from the southwest 10-25 km/h. Freezing level at valley bottom.
Terrain and Travel Advice
- Be careful as you transition into wind-affected terrain.
- Avoid freshly wind-loaded terrain features.
- Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
Problems
Wind Slabs
Be mindful of newly formed windslabs from recent snow and wind. Older windslabs are also still present and could be sitting on a crust or facets, which may increase their potential for triggering.
