Thanks for sharing your observations via the MIN if you are going out into the backcountry.

30 cm to 50 cm of new snow is expected by Friday afternoon, forming touchy and widespread slabs. This overlies wind-affected snow in lee terrain at upper elevations and a thin melt-freeze crust on southerly slopes. At lower elevations, the snowpack is expected to be heavy and wet.

A supportive crust is found 60 to 80 cm deep on all aspects except on high, north-facing alpine terrain, and the recent settling snow is bonding well to it.

A weak layer of facets and surface hoar from February is now 90 to 150 cm deep and a layer of facets and surface hoar from late January is 130 to 190 cm deep. No recent notable test results have been seen on these layers.
