A large winter storm bringing heavy snow and strong wind begins overnight and is expected to last into Wednesday. As new snow accumulates, avalanche danger will rise, and wind-loading could trigger a natural cycle. You can trigger large avalanches in the new and drifted snow, and some could step down into deeper weak-layers, breaking wide across terrain features and running long distances. Avoid traveling on or under slopes steeper than about 30 degrees.
