Pericolo valanghe
In sintesi
At the upper elevations, backcountry travelers could trigger pockets of surface slab up to 30 inches in depth on very steep, wind loaded slopes. Beware of large cornices and avoid the terrain below them. The mid elevation snowpack is mostly stable and avalanche activity is limited to isolated pockets of soft slab up to 18 inches deep in very steep, wind loaded terrain. With above freezing overnight lows at the lower elevations, afternoon warming and a chance of rain showers could also bring about the possibility of shallow wet slides below 7,000 feet.
Avalanche Discussion
A fast moving system moving is expected to bring two to four inches of new snow to the higher elevations by dawn. Light snowfall is expected in the mountains on Tuesday. One to two inches of accumulation are possible. Temperatures will rise into the 30s in the mountains and into the 40s in the valleys. Winds will be southwest at five to ten miles per hour.The general avalanche hazard is expected to be MODERATE. The potential persists for humans to trigger pockets of slab up to 30 inches deep in steep, wind loaded avalanche paths at the higher elevations. Sunlight and increasing temperatures will increase the sensitivity of these slabs to human triggers, may cause cornices to collapse and could initiate shallow wet slides in steep couloirs and cliff areas. Avalanches are unlikely at the mid and lower elevations except on steep banks and road cuts.
