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

There is a LOW avalanche danger below 1,000’ where little snow remains.
