In sintesi

Dangerous avalanche conditions exist. Skiers and riders could easily trigger very large, destructive persistent slabs in steep avalanche terrain. While the likelihood of triggering these slabs is slowly decreasing, the consequences remain high. Don’t let previous tracks fool you into thinking a slope is stable, and continue to make conservative terrain choices. Backcountry travelers could also trigger small pockets of wind slab that could easily step down and release the much larger persistent slab below.

    Strong southwesterly to westerly ridgetop winds have transported recent snowfall and increased the load on persistent weak layers of faceted snow. These strong winds have also scoured windward slopes. This scenario continues to increase the spatial variability of dangerous, persistent slabs that could reach depths of four feet. These slabs are just waiting for a trigger, and any slope that has not slid should be viewed as suspect. Take note of obvious signs of instability, which include recent avalanche activity, whomphing and cracking, and avoid avalanche terrain where these indicators are present.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Light, scattered snow showers will linger this evening before a drying and cooling trend takes hold as high pressure moves into the region. Overnight lows in the mountains will drop into the single digits before rising into the mid-teens during the day. Westerly ridgetop winds will veer to the northwest and decrease to 15 to 25 miles per hour.Dangerous avalanche conditions exist, and the general avalanche hazard is expected to remain CONSIDERABLE on Sunday. While the likelihood of triggering persistent slabs to depths of four feet will slowly decrease, the consequences remain high. Don’t let previous tracks fool you into thinking a slope is stable, and continue to make conservative terrain choices.
