The midpack in most areas is weak and facetted. Any slab sitting overtop of this weakness should be considered suspect and there is a high level of uncertainty and variability concerning this layer.
Recent winds ranging from East to SW have created some new windslabs in alpine and treeline features. In some cases, these have been observed to provide enough weight to step down to the deep persistent layer, causing a larger avalanche.
Deep persistent slabs are best managed by:
Cornices are best managed by:
A bit more cloud with a chance of trace amounts of precip for Monday before skies clear. Cold nights will be the price to pay for sunny afternoons with maybe some light winds reaching -5 C at valley bottom elevations. Watch for the sun to create moist snow on steep SW slopes given these conditions.
The snowpack is quite localized. 10-40 cm of storm snow (often windslab) rests on weak facets. Deeper layers of weak facets and depth hoar are common. A supportive midpack can be found, but it is often friable and may contribute to deeper failures. Lower elevations have unsupportive bottomless facets!
No new avalanches were reported today.
