{"blocks":[{"key":"ccl71","text":"Recent sun and warm air well into the alpine had the greatest impact on the upper snowpack, showing signs of instability and promoting further slab development and cohesion. This may be most concerning where these slabs sit above an old thin crust on south aspects and feathery surface hoar crystals in wind-sheltered areas. New surface hoar formation can be found on slopes where it was protected from the warm temperatures, sunshine and wind. Northerly aspects will likely see fresh wind slab development at upper elevations on leeward slopes and melt-freeze conditions may exist on most aspects and elevations.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":100,"length":20,"key":0},{"offset":143,"length":29,"key":1}],"data":{}},{"key":"dt88h","text":"The lower snowpack is characterized by a few crusts formed during warm periods over the last month.
