{"blocks":[{"key":"dofk9","text":"Incremental snowfall and wind formed wind slabs in the alpine and open areas at treeline that may remain possible to human trigger. Cornices are large and looming after a week of successive storms. Intense solar radiation is rapidly destabilizing recent snow on steep, sun-exposed slopes and weakening cornices.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"fhqbm","text":"A weak layer of surface hoar may be found 50-100 cm deep. Reports indicate that this layer may be absent in the northern tip of the region (check out this MIN from Sugarbowl). However, observers have identified the layer in snow profiles ranging from Barkerville to Valemount (see this MIN from Mt Greenbury, this MIN from the Trophy Mountains, and this MIN from Allan Creek). Sheltered north, northeast, and east facing slopes near treeline are the most suspect.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":155,"length":3,"key":0},{"offset":286,"length":3,"key":1},{"offset":314,"length":3,"key":2},{"offset":354,"length":3,"key":3}],"data":{}},{"key":"dtrep","text":"This persistent slab problem is transitioning into a low probability/high consequence scenario. Snowfall, wind, temperatures, and solar radiation have increased the depth and slab properties of the snow above the weak layer, making it more difficult to trigger and masking obvious clues that the problem is present (i.e. cracking, whumpfing). However, if triggered, avalanches will likely be larger in size and getting caught could have more serious consequences. Managing this problem requires a patient and diligent mindset, implemented by avoiding suspect slopes and maintaining conservative terrain margins. This persistent weak layer will likely pose the threat of a low probability/high consequence avalanche until there is a substantial change in the snowpack.
