Avalanche Forecast

High

On Wednesday there were a few size 1 avalanches triggered by explosives in the storm snow with impressively wide propagation.

Thanks for the observations and please continue to post your reports and photos to the Mountain Information Network. It is really helpful for forecasters!

At treeline and above any new snow is dry and powdery and the slightly older snow is settling and bonding. Near the peaks much as 100 cm fell this week, but time and warm temps reduced it to half that. Storm snow amounts lessen and becomes a frozen crust at lower elevations, disappearing around 500 to 700 m.

This week's snow covers a rain runnelled crust. Last week's 'pineapple' rain storm saturated the snowpack at all elevations and pretty much removed all layering.

• Make observations and assess conditions continually as you travel.
• Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
• Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
