Travel and Terrain Advice
Possible varied snow conditions as new snow total increase and further buries the sun crust formed on Friday. Watch for frozen lumps of snow that will have dislodged from trees and may be near the surface. Poor visibility and the dusting of new snow may have obscured open glide cracks that are a hazard at lower elevations.
Avalanche Problem

Avalanche
No new activity has been reported in the previous few days.
Snowpack

Periods of sunshine on Friday and warmer temperatures have created a sun crust on the solar aspects which have now been buried. Gusting north west winds will be transporting this latest new snow onto lee slopes.
Weather
Moderate northwest winds and continued snowfall is forecasted for the weekend. Temperatures will remain cold before rising above freezing at the start of next week.
