advisory discussion

The strong Pacific storm has resulted in very heavy snow accumulations across our forecast region.  Snotel sites are reporting 48 hour accumulations of 24 inches in the Clearwater Mountains, 14 inches in the St. Joe's, 25 inches in the Cabinets, and 15 inches in the Selkirks.  All this new snow has come with rising temperatures and significant inputs of strong westerly winds.  These three factors alone will increase the avalanche danger to the degree where natural avalanches are possible.  Add to that the fact that there are persistent weak layers in the pack and the new snow fell on variable hard snow surfaces and that is the factor that increases the danger to where natural avalanches are likely, on numerous aspects.
