We have received very little information on avalanche activity for this region. From the little we have heard, there were no new avalanches to report from Wednesday. Forecast heavy precipitation should mean that the likelihood of triggering avalanches is on the rise.We would very much appreciate it if you spend a moment to submit any observations you have to the Mountain Information Network here, even if it is just a photo. Thanks!

Rain is now falling as snow at upper elevations building reactive storm slabs which sit over a predominant thick crust. It is difficult to predict where and when rain will switch to snow, but expect the transition to happen and by Wednesday and most precipitation will fall as snow above 1300 m.At below treeline elevations, a spring snowpack exists. Rain has saturated and weakened the upper snowpack. Forecast rain will continue this trend.
