Early Season Conditions Update #9

Normal caution is advised throughout the forecast area when traveling in the backcountry.  A useable snowpack of 2-3' exists above 8000' with generally safe avalanche conditions. Small wind slabs may exist or develop in wind loaded areas in near treeline and above treeline terrain through the week.   Practice safe travel protocols when in or near avalanche terrain.

Early season conditions update #8

Continue to use normal caution when traveling in the backcounrty. Rain, snow, and wind during the storm on Sunday and Monday could allow wind slabs, possible storm slab, or minor loose wet instabilities to form in some areas where enough snow accumulates. Near and above treeline terrain holds the best potential for these areas of instability especially in areas where significant wind-loading occurs. These instabilities should diminish during the week as the weather calms down.

Early season conditions update #5

Normal caution, focusing on best travel practices in or near avalanche terrain is appropriate for most of the forecast area. Ongoing concern for deep slab avalanches in the Mount Rose portion of the forecast area is decreasing, but not entirely gone. Large destructive avalanches are unlikely but not impossible in isolated areas. Uncertainly remains for terrain that matches the location of the deep slab avalanche problem. Do not underestimate potential avalanche size or consequences.

Early season conditions update #4

A deep slab avalanche problem has formed with human triggered avalanche activity in the Mount Rose portion of the forecast area. Feet of new snow continue to accumulate in some portions of the forecast area above 8,000' as the current storm progresses. Wind slab avalanche problems remain a concern area wide. Heightened avalanche conditions exist on specific terrain features. Evaluate snow and terrain carefully; identify features of concern. Large destructive avalanches are possible.

General Spring Avalanche Statement

At the tail end of this historic winter, we have stopped issuing daily avalanche advisories for the 2016-2017 season. For more info explaining the chosen end date, click here. Avalanche activity will invariably occur this spring. Continued daily wet snow melt-freeze cycles and additional storm cycles will impact the forecast area. Some information and resources to aid in trip planning and decision making have been assembled on the advisory page.

MODERATE avalanche danger exists this morning due to the potential for loose wet and wet slab avalanche problems. In areas that received little to no snow surface refreeze last night these problems are possible beginning early this morning. In areas where a refreeze did occur these avalanche problems will develop as daytime warming occurs, accelerating once cloud cover clears from the area today. Avoid travel in avalanche terrain once wet surface snow begins to loose supportability.

LOW avalanche danger early this morning will increase to MODERATE avalanche danger in response to daytime warming as the day progresses. Areas of loose wet avalanche problems are expected to develop on all aspects at all elevations today. Cornice collapse may continue to occur today, presenting an additional hazard to backcountry travelers.

LOW avalanche danger this morning will rise to MODERATE avalanche danger as the day warms up. Loose wet avalanches will become possible again today on slopes where wet snow forms. While triggering a wind slab has become unlikely except in a few isolated places, cornice failures remain possible today especially as warming weakens the cornices. Avoid slopes where wet, unsupportable snow exists and complex or extreme terrain where isolated wind slabs may exist. Give all cornices a wide berth.
