Schweitzer ski patrol is encouraging and offering weekly free "Transceiver Sundays" (clock tower at 10:00 a.m.) to all interested public with two permanent practice areas and one more difficult challenge that is on a less regular basis. All they ask is that the public covers up their tracks and if practicing digging techniques, please replace your divot. This is a great way to keep on your A game for those venturing out of bounds.

Solar loading during the inversion temperatures which have hit the 40's at elevation this week have increased the surface melting on solar aspects. The melting on the surface has increased the amount of water percolating into the snowpack which makes solar aspects more susceptible to loose wet avalanches.
Current snowpack is right side up and most areas have a firm base of snow. The weakest layer is the layer of facets about 10cm down in the sugary storm snow, which is potential bad news for when we recieve more snow in the (hopefully) near future; this layer won't be supportive enough.
Thank you Gabe White, IPAC volunteer forecaster for excellent observations. Check Facebook and Instagram for a photo of the large surface hoar that is being seen in the field.
A big ridge over the pacific is pushing cold air far south and north around our forecast region. We continue to sit in a high pressure for the next couple of days with inversion conditions. Tuesday, Wednesday and Thursday are all mostly sunny with highs in the upper 30's and nighttime lows just below freezing. Look to Friday for a shift in weather patttern and an increased chance in precipitation.

Avalanche conditions change for better or worse continually. Backcountry travelers should be prepared to assess current conditions for themselves, plan their routes of travel accordingly, and never travel alone. Backcountry travelers can reduce their exposure to avalanche hazards by utilizing timbered trails and ridge routes and by avoiding open and exposed terrain with slope angles of 30 degrees or more. Backcountry travelers should carry the necessary avalanche rescue equipment such as a shovel, avalanche probe or probe ski poles, a rescue beacon and a well-equipped first aid kit.
