Avalanche Advisory

7,000-8,500 ft.
Below 7,000 ft.

bottom line There is a MODERATE overall avalanche danger today. Heightened danger can be found along ridges where the wind has drifted snow into fresh drifts. Human triggered avalanches are possible or maybe even likely if you provoke these drifts. Especially watch for these if you are in areas that have a thinner and weaker preexisting snowpack. Shallow rocky spots scattered throughout deeper snowpack areas are suspect as well.

description
You will most likely find numerous fresh wind slabs that are likely to release if provoked. These are always the most sensitive during and just after they've formed. This is a manageable problem for those with good avalanche experience in that you can recognize areas that have fresh drifts and avoid them. However, a greater concern would be where it's perhaps not quite so obvious that the wind has drifted snow into areas that have buried weak faceted snow which could then collapse. The best policy is to avoid the fresh wind drifts. This issue is most pronounced on the lee sides of ridges mostly on northeast through southerly facing slopes. Watch for crossloaded terrain features on the windward slopes as well. |

weather The little disturbance that bumped the winds and is giving us a little snow will move through by mid day today. We shouldn't see much more snowfall. Northwest winds will start to slow and ridgetop temperatures will get into the 20s. Clouds should break a bit as the day progresses. We'll have another small disturbance tonight into Friday morning then a warming trend into Saturday. More storms are on deck. |
