Summary

Most slopes do not have enough snow or lack the required slab for dangerous avalanches. You might trigger a small avalanche in very steep, alpine terrain that faces north, through northeast, to east. If you see signs of previously wind-drifted snow like pillows or smooth, hard, hollow-feeling snow, consider moving to a more wind-sheltered area.

A storm moves into the areas tonight, this will likely increase the avalanche danger on Tuesday. Watch for changing conditions as the snow starts to fall and the wind increases.

The avalanche danger will increase across the Northern Mountains on Tuesday as a weak shortwave trough moves through the state. The old snow surface is weak and won't handle much load. The most dangerous slopes will be north, northeast, and east-facing slopes near and above treeline, where the old snow is the weakest. If you plan to travel in the mountains over the next few days, be aware that conditions have changed. Places you could safely travel since the beginning of the season will no longer be safe. 

Other aspects generally don't have enough snow or have such spotty snow cover that a few inches of snow, even with some wind, won't do much to change the danger on those aspects on Tuesday. However, a stronger storm is forecast for Thursday into Friday, and right now, this one looks strong enough to cause more widespread avalanche problems. Snowfall amounts should be enough to create dangerous avalanche conditions in the areas that receive the most snow. Check back frequently over the next few days for the most up-to-date avalanche conditions.
