There is a widespread persistent weak layer (PWL) of faceted snow on northerly-facing slopes at the mid and upper elevations. On some upper-elevation slopes, there is a stronger slab on top of the PWL where it is possible to trigger an avalanche. Observers in the Salt Lake mountains have also noted the entire snowpack is now nearly all facets:

with similar conditions in the Ogden mountains likely.
Our locator rose shows where this PWL exists: mid and upper elevation aspects facing northwest through northeast, including upper-elevation aspects facing west and east. A common theme from the three observations is that, although the PWL is present, it is currently not a widespread problem as we lack a slab on top of the facets, but with heavy, dense snow and strong winds forecasted, expect a rising avalanche danger as we place a load on top of this PWL.
