{"blocks":[{"key":"8uabu","text":"5-15 cm of snow is forecast to fall overnight Saturday and into Sunday with moderate south winds, burying a surface hoar layer that was reported in sheltered locations at treeline. New snow will add to recent 5 -25 cm of snow from earlier this week that has covered a widespread layer of weak surface hoar.  The highest snowfall amounts were reported in the south Monashees while in the far north there are regions with only trace amounts, as reported in this MIN from Clemina.  The surface hoar (5-15 mm) that is buried 10-35 cm has recently been most reactive in sheltered north aspects (see avalanche summary). It sits on a variety of surfaces:  old wind slabs and wind affect in exposed terrain, a thin sun crust on steep solar and faceted snow.  Below 1600 m, 20-30 cm of snow is settling above a decomposing melt freeze crust.
