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.
