Areas of MODERATE avalanche danger exist at all elevations on slopes 32 degrees and steeper due to a combination of wind slabs and persistent slabs. Several human triggered avalanches occurred yesterday with signs of persistent instability present in other areas. Human triggered avalanches are possible again today in a variety of areas. Isolated natural avalanche activity is unlikely but not impossible today. Exercise caution and conservative decision making during backcountry travel.

THIS ADVISORY WILL BE UPDATED ON JANUARY 2, 2017 at 7:00 am.

Human triggered avalanches will remain possible today and tomorrow on some slopes steeper than 32 degrees. MODERATE avalanche danger exists at all elevations. Evaluate the snowpack and terrain carefully; identify areas where instability may exist, and use this information to avoid those areas of concern. As more snow and wind imapct the region this week the avalanche danger will increase.

Human triggered avalanches will be possible today at all elevations due to new wind slabs, new storm slabs, and lingering persistent slabs. Some avalanches could be large and have serious consequences. Evaluate the snowpack and terrain carefully; identify areas where instability may exist, and use this information to avoid those areas of concern. MODERATE avalanche danger exists at all elevations. As more snow and wind impact the region this week, the avalanche danger will increase.

CONSIDERABLE avalanche danger at all elevations exists today, increasing to HIGH danger this evening. Human triggered avalanches are likely and natural avalanches are possible. A complex mix of wind slab, storm slab, and deep slab avalanche problems exist. The majority of avalanche activity today is expected on slopes 35 degrees and steeper but could occur on slopes 30 degrees and steeper in isolated areas. An Avalanche Warning has been issued starting 4 pm today lasting through 7 am Thursday.

Moderate avalanche danger exists throughout the forecast area due to deep slab and wind slab avalanches.  Dangerous avalanche conditions continue to be possible with many deep slab avalanches occurring throughout the forecast area within the last 48 hours including a skier triggered deep slab avalanche in the Mt. Rose area yesterday partially burying a skier and a car.  Large avalanches with severe consequences could be human triggered today.   Cautious route finding and conservative decision making are essential.

UPDATED @ 1:30PM 

Due to snow levels rising sooner than expected, natural and human triggered avalanches are likely this afternoon and tonight. Large destructive deep slabs, wind slabs, and wet slabs that run long distances are likely as more rain and snow impact the region. Very dangerous avalanche conditions exist. Travel in or near avalanche terrain is not recommended. The avalanche danger has increased to HIGH at all elevations due to rain, wind, and snow impacting the region.

Natural and human triggered avalanches are certain today due to the significant amount of rain on snow expected below 9300 ft. and heavy wet snow loading above 9000 ft. Large, deep, destructive wet slab, deep slab, and wind slab avalanches will occur today as well as loose wet avalanches. Avalanches could run farther than expected and involve almost the entire snowpack. Avoid travel in or near avalanche terrain or runout zones today. EXTREME avalanche danger exists at all elevations.

Dangerous avalanche conditions still exist and large, deep, destructive human-triggered avalanches remain likely due to deep slabs and wind slabs. CONSIDERABLE avalanche danger exists at all elevations. This danger rating is when the most avalanche fatalities occur. Carefully evaluate the snowpack and terrain and use this information to create safe and conservative travel plans. Avoid areas where avalanche problems may exist. The avalanche danger will rise to HIGH again tonight as more snow and wind impact the forecast area.

HIGH avalanche danger exists for all elevations and aspects due to a combination of wind slab, storm slab, and deep slab avalanche problems. Travel in avalanche terrain, on or below slopes 30 degrees and steeper is not recommended. Avalanches could run into areas of mature forest. A backcountry avalanche warning is in effect through at least 7 am Wednesday.

MODERATE avalanche danger exists at all elevations due to newly formed wind slabs and unlikely but not impossible lingering deep slabs. Human triggered avalanches may remain possible today especially in regards to the wind slabs that formed yesterday. Evaluate the snowpack and terrain carefully before committing to any route and use this information to identify and avoid areas of concern. This data can also help find safer areas to recreate where good snow conditions exist.

The avalanche danger has decreased to LOW. Low avalanche danger does not mean no avalanche danger. Unstable snow may still exist on isolated terrain features and small avalanches could still occur in isolated or extreme terrain. Continue to evaluate the terrain and snowpack while traveling in the backcountry to identify where these isolated areas of unstable snow may still exist and avoid those slopes.

LOW avalanche danger exists at all elevations. While triggering an avalanche has become unlikely, some unstable snow may still exist on isolated terrain features and small avalanches could still occur in isolated or extreme terrain. Continue to evaluate the terrain and snowpack while traveling in the backcountry to identify where these isolated areas of unstable snow may still exist.

Human triggered wind slab and storm avalanches are likely today. Natural avalanches are possible. CONSIDERABLE danger exists at all elevations. Some large and destructive avalanches could occur. Dangerous avalanche conditions exist. Carefully evaluate the snowpack and the terrain before committing to any slopes. Use this information to make conservative and cautious decisions and plan safe routes of travel that avoid avalanche problems. As another strong winter storm impacts the region tonight through Monday morning, the avalanche danger will increase.

HIGH avalanche danger exists at all elevations. Due to heavy snow, intense snowfall rates, and gale force winds human triggered wind slab avalanches and storm slab avalanches will be very likely today and natural avalanches will be likely. Some avalanches could be large, deep, and destructive. Travel in or near avalanche terrain or in the runout zones of avalanche paths is not recommended.
