{"blocks":[{"key":"4ihnn","text":"The next storm arrives midday on Friday bringing 5-10 cm of snow and strong southwest wind. At upper elevations, a total of 15-25 cm of snow has accumulated in the past week over a substantial crust that formed in early December. A thin crust from a brief warm-up on Tuesday can be found within this snow. Strong west and southwest winds have redistributed available snow into dense wind slabs in wind-exposed areas. These wind slabs may be possible to human trigger in immediate lee terrain features (for example, just down-wind of ridges), particularly where the snow is poorly bonded to a crust.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"d9q4","text":"We have uncertainty about the distribution of a layer of surface hoar or facets near the early December crust.
