{"blocks":[{"key":"enojt","text":"There have been substantial changes to the snowpack over the past few days. 40-60 cm of snow fell during the weekend storm above 1900 m. Higher snow totals fell in the northern and western parts of the region. Extreme winds originating from the southwest and shifting to the northwest have created a tricky loading pattern in the alpine and have elevated concern for cornice triggers. These winds drifted the snow into deeper, stiffer slabs on leeward terrain features that may remain prone to human triggering. During a warming event Saturday night, rain saturated snow surfaces up to around 1900 m that have since refrozen with cooling temperatures.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":444,"length":7,"key":0}],"data":{}},{"key":"1un7v","text":"A weak layer of surface hoar may still be found about 90 cm deep around Golden and Kimberley, 50 cm deep around Invermere, and 130 cm deep along Kootenay Lake.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":16,"length":12,"key":1}],"data":{}},{"key":"31pkl","text":"As usual for the Purcells, the base of the snowpack contains basal facets and it remains possible to trigger these deep weak layers in shallow rocky start zones or from a heavy trigger such as a cornice fall or explosives.
