The combination of a building storm slab on smooth open slopes, and very rugged travel in forested terrain, will make it challenging to find safe good skiing in the coming days.

Terrain and Travel Advice
Problems
Avalanche Problem 1: Storm slab
What Elevation? - Treeline, Alpine
Which Slopes? - North, Northeast, East, Southeast, south, Southwest, West, Northwest
Chances of Avalanches? - Likely
Expected Size? - Small - Large

New snow in the coming days will build fresh slabs over a fresh layer of surface hoar. Expect avalanche activity on smooth open slopes.

Avalanche Summary

If there's enough to ride, there's enough to slide. Be sure to bring a transceiver, shovel and probe if you venture out.

Snowpack Summary

Snow is starting to stick in the high-country. There is approximately 100cms of snow on the ground in the Alpine, 60-80cm at treeline, and 10-15 at highway elevation.

There is 6-12mm surface hoar on the surface in all open areas treeline and above. Expect this to provide a sliding layer for the incoming new snow.

Hidden rocks and logs lurk just below the snow surface in all terrain below treeline. Glaciers will have poor coverage with just enough snow to hide small crevasses.
Weather Summary

Confidence

Low - Uncertainty is due to the limited number of field observations.
