{"blocks":[{"key":"3m446","text":"The incoming storm is expected to rapidly add a new layer to our snowpack. The new snow will fall on 15-25 cm of snow from over the weekend overlying a weak interface. At higher elevations, winds from the southwest drifted this snow into slabs on leeward features. Elsewhere this recent snow remains unconsolidated. The interface below it may present as surface hoar in many sheltered locations.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":247,"length":7,"key":0},{"offset":354,"length":12,"key":1}],"data":{}},{"key":"duvf3","text":"The upper snowpack consists of around 70 to 120 cm of snow that overlies a variable weak layer of surface hoar and a crust from mid-December (down 70-90 cm), as well as a deeper weak layer of sugary faceted grains and a crust buried in late-November (down 100-200 cm). Both of these persistent weak layers produced many large and destructive avalanches during and in the days after last week's storm. Snowpack tests continue to produce sudden and propagating results on these layers (like this MIN report from Disease Ridge on Sunday). This fundamentally unstable snowpack structure remains a serious concern with the incoming storm.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":401,"length":14,"key":2},{"offset":447,"length":11,"key":3},{"offset":494,"length":10,"key":4}],"data":{}}],"entityMap":{"0":{"type":"LINK","mutability":"MUTABLE","data":{"href":"https://www.avalanche.ca/glossary?q=leeward#leeward","target":"_self","url":"https://www.avalanche.ca/glossary?q=leeward#leeward"}},"1":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/glossary/#surface-hoar"}},"2":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/glossary/#snowpack-tests"}},"3":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/glossary/#propagation"}},"4":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/mountain-information-network/submissions/8956a025-8227-4dc9-abe1-7e01533ad71c"}}}}
