Spring has rolled into the mountains with warm weather, sunshine and some rainy days in between. Although winter is coming to a close, avalanche season is still well underway. As the snowpack heats up, melts down and loses its strength, small to large wet avalanches are expected to continue region wide - into May. Be aware, these can release naturally or be easily triggered on steep slopes that are wet and saturated. The key is: If the snowpack frozen and hard = avalanches are unlikely. If the snowpack is soggy and supportable to your snowmachine/skis/boots/etc, it will easily slide down the mountian if the slope is steep enough = avalanches are probable. #playsafe
Turnagain Advisory
Saturday, April 29th 2017
The avalanche danger is expected to remain at MODERATE on slopes above 1,000' for wet avalanches this weekend. The danger could rise to CONSIDERABLE by the early evening hours in the event of significant daytime warming. Keep in mind the snowpack continues to slowly warm and destabilize as it undergoes the springtime transition. Human triggered wet loose and wet slab avalanches are possible on slopes over 35 degrees with a wet snowpack. Natural wet snow avalanches will also become possible later in the day as the snowpack becomes wet. Additionally, glide cracks continue to slowly creep open and can release without warning.  There is a LOW avalanche danger below 1,000’ where little snow remains.  Hiking on summer trails during the springtime warm-up (including the Byron Glacier …
