Avalanche Summary
Recent avalanches have been limited to loose wet sluff to size 1.5.
Snowpack Summary
North and Northeast aspects above 2000m continue to hold up to 20cm of dry snow, otherwise, the surface condition is crusts. The carrying strength of the crusts vary depending on aspect and elevation as well as proximity to rocks, etc.... Generally speaking, the crusts have been going moist in the afternoon and then refreezing at night in all but the lowest terrain. Immediate lee features in the high alpine hold isolated softslabs that may still be reactive to rider triggering. Planar results have been observed in sheltered start zones. In some places outflow winds have reverse loaded pockets of the most recent storm snow onto the melt freeze surfaces of south facing slopes, creating small, reactive slabs in unusual places.In the upper snowpack (down 50-70cm) a significant melt-freeze crust lingers. Some facetting has been observed above and below this crust. At the same interface spotty surface hoar may linger on high, sheltered north facing terrain. There has been no recent stability test results on this layer.Cornices are huge and will continue to grow with the forecasted precipitation.
