Avalanche Forecast
Avalanche Bulletin - Glacier National Park
Very limited observations recently assess each slope independently. Expect some natural avalanche activity in extreme terrain, human triggered avalanches are still possible.

Travel and Terrain Advice
- Dig down to find and test weak layers before committing to a line.
- Use caution in alpine and open treeline lees. Recent snowfall has created storm slabs.
Avalanche Summary
No new avalanches were observed in the highway corridor yesterday or reported from the backcountry.
Snowpack Summary
Another 20+ cm of new snow fell in the last 24 hours at tree line. The new snow overlies a variety of older surface conditions, from wind slabs in exposed areas at and above tree line to protected storm snow in sheltered areas. The Nov 23rd/26th crust complex is now buried approximately 50cm.
Weather Forecast
A dirty ridge of high pressure forms over us today, giving us a mixed bag of weather, from sunny periods to isolated flurries. The freezing level will hover around 1000m, winds will be moderate from the SW and an Alpine high of -7. A cold front will pass by later this afternoon into tonight, depositing another 10-15cm of new snow.

20+ cm of new snow with moderate winds fell in the last 24 hours. Expect slab formation on exposed terrain features and unsupported convex rolls. The storm snow has buried old wind slabs, which could still be reactive on specific terrain features.
