Snowpack Summary
Recently developed surface hoar and near-surface facets are getting gently buried by light snowfall, potentially creating a weak interface which could become reactive with enough new load from snow and/or wind-transport.Other buried surface hoar layers exist in the upper 15-25cm (with sudden test results on these layers in some locations). Soft and hard wind-slabs can be found on certain slopes in the alpine and around treeline. Generally light snowfall amounts are forecast for the region over the next few days. Without the certainty of heavy or rapid loading, it's hard to know when the weight of new snow building over buried weaknesses might reach a tipping point. Areas with locally heavier snowfall should reach this point sooner. Facets at the base of the snowpack could create a deep persistent slab problem that deserves attention in shallow snowpack areas on planar rocky slopes.
