{"blocks":[{"key":"1dchb","text":"Prior to Friday's storm, up to 35 cm of snow from last Sunday buried the January 30 interface which consists of a melt freeze crust at lower elevations and on solar aspects extending into the alpine and widespread surface hoar in sheltered areas at and below treeline which is typically up to around 20 mm in size and very weak in some places. Prior to Friday's storm, the older storm snow had not formed a slab in most places except for where it was wind loaded. With warming and sun this weekend, rapid settlement is possible and this may result in the formation of a more widespread reactive slab over the weak surface hoar and crust. Ongoing wind over the past week has formed reactive wind slabs in exposed terrain at higher elevations and new wind slabs may build during Friday's storm.
