Avalanche Forecast

Moderate -

Tuesday will be mainly cloudy with another 5cm expected. Temperatures will show an abnormal trend, starting out at -15c and dropping through the day into the -20's. Winds should be relatively light from the west.

Wednesday looks cold with temps between -20 and -30.

Several naturally triggered loose dry avalanches were observed in Alpine terrain. These slides were up to size 2.0 and occurred on SE, N and NE aspects.

Up to 30cm of new snow fell at treeline over the past 24 hours, with an additional 3 to 5cm through the day. In general, this new snow is not bonding well with the underlying surface, especially in areas with this previous surface was hard wind slab or sun crust. Fresh surface wind slabs 30 to 60cm thick are evident in the Alpine and just into treeline, and the strong winds will continue to build these through the night. Forecasters observed cracking in steeper terrain at 2400m on Monday. Lee and cross-loaded terrain is a concern for human triggering. Several loose dry avalanches were also observed in steep terrain.

• Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
• Avoid lee and cross-loaded slopes at and above treeline.
• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
