Highlights
Human triggered slab avalanches and shallow loose snow sluffs are possible in steep terrain at the mid and upper elevations. Avalanches are unlikely at the lower elevations.

Avalanche Discussion
A high pressure ridge will continue to dictate our weather regime. Skies are expected to be mostly clear above areas of morning valley fog. Temperatures will again drop into the teens in the mountains and to near zero in the valleys overnight. Daytime temperatures will be slightly warmer than today and approach 30 degrees in the mountains. Winds will back towards the southwest and remain light.The potential for humans to trigger slab avalanches at the mid and upper elevations is slowly decreasing. This decrease is attributed to a gradual decrease in the sensitivity of these slabs to human triggers and to the concept that areas of unstable snow are becoming increasingly isolated in distribution. That said some potential may persist for humans to trigger slab avalanches up to two feet in depth in steep terrain at the mid and upper elevations where the general avalanche hazard is expected to be MODERATE. Avalanches are unlikely at the lower elevations.
