{"blocks":[{"key":"4cfqf","text":"The overnight storm is expected to rapidly add a critical new load to our snowpack. This will create a widespread storm slab problem at all elevations that will need to be managed conservatively. At higher elevations, strong southwest winds are expected to exacerbate the reactivity of the new snow in drifted areas. The new snow is falling on another recent layer of surface hoar that has been showing increasing reactivity as snow accumulates.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"1o48","text":"Buried deeper in the snowpack, there are multiple weak layers, which include a variable layer of surface hoar and crust from mid-December (down 70-90 cm) as well as a deeper layer of sugary facets and crust buried in late-November (down 120-200 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 as new snow and wind add a critical load and increase the likelihood of triggering these large and destructive avalanches.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":190,"length":6,"key":0},{"offset":382,"length":14,"key":1},{"offset":428,"length":11,"key":2},{"offset":475,"length":10,"key":3}],"data":{}}],"entityMap":{"0":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/glossary#faceted-snow"}},"1":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/glossary/#snowpack-tests"}},"2":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/glossary/#propagation"}},"3":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/mountain-information-network/submissions/8956a025-8227-4dc9-abe1-7e01533ad71c"}}}}
