While conditions are generally safe, expect some minor sluffing from steep terrain during the heat of the day.

A stable pattern with more seasonal temps will persist for the remainder of the week. The cold air in valley bottoms is beginning to mix with the warmer air aloft.Wednesday: Cloudy with sunny periods. Alpine temperature: Low -4 C, High 3 C. Light ridge wind. Weak temperature inversion.No precipitation is forecast until the weekend.

Cold temps have facetted the upper snowpack. Isolated pockets of wind slab in ALP areas sitting on an old snow interface of facets, sun crust, wind effect, or surface hoar. 2 buried crusts extend into the lower limits of the alpine, both are dormant.  The upper crust is providing mid-pack strength, but has facets above and below it.

Isolated small loose snow avalanches occurred in steep alpine terrain with today's warming temps.
