Due to current snowpack conditions the Kootenai National Forest will begin posting advisories begining December 15th, 2017.  This will of course be snowpack dependent.  Until then continue to keep an eye on the weather and pre-existing snow conditions as this will form the begining of our season history and the potential weaknesses to come.

The snow trends in the mountains are currently being driven by the inversion.  Large surface hoar was found on all aspects below 5100' , with smaller hoar found at higher elevations.  Near surface faceting found on all aspects. The pack hasn't changed much since Thursday with some melt freeze crusts forming on the southern aspects at higher elevations.

Not a lot has changed with the weather or snowpack since the last advisory. The good news is... most area have a firm base of snow to help limit the amount of basal rotting that's typical during long spells of high pressure. The bad news is... the upper portion of the pack has 2 distinct weak layers and is not supportive enough to receive more snow on top of it.

With not much snow recently or much in the future, the forecast area will remain at a LOW danger rating. The biggest area of concern would be above treeline on steep slopes. Loose snow avalanches are possible in isolated areas.

Rain and warm temperatures over Thanksgiving had a toll on the depth of our snowpack. The newer snow is fairly well bonded to the Thanksgiving crust, but small windloaded pockets were observed on all aspectsSurface hoar and near surface faceting was also observed.  Looking ahead at the weather forecast, no new precipitation is expected for a while and daytime highs over the weekend could form sun crusts.

It's been at least 2 weeks since the Cabinet or Selkirk mountians have seen any new snowfall. The recent high presusure and colder temperatures have started to break down the snowpack (near surface faceting). In most areas the snowpack can be summed up in 2 parts. The bottom half of the pack is old firm frozen snow and the upper portions of the pack is light unconsolidated snow. In it's current state the snowpack doesn't present much avalanche danger.

I hope you're all out enjoying the sunshine! The avalanche danger is on the rise while the sun is out. With these warm temperatures and solar radiation be aware of the possibility of wet avalanches.  Solar aspects will be the most likely spot to find unstable snow.
