Avalanche Forecast
Issued: Apr 24th, 2016 8:12AM
The alpine rating is Wet Slabs and Storm Slabs.
, the treeline rating is , and the below treeline rating is Known problems includeSpring conditions. Plan to travel when the snow surface is frozen and strong.
Summary
Weather Forecast
A mix of sun and cloud, light winds and possibly a few convective showers are expected over the next few days. The daytime freezing level stays around 1700 m until Tuesday, when it begins to climb again.
Avalanche Summary
No recent avalanches have been reported. A few large wet slab avalanches were observed 5-7 days ago. At least one of these failed on at ground. Most operators have shut down for the season. Please continue to share your backcountry observations through the Mountain Information Network.
Snowpack Summary
Isolated storm slabs may be found in the high alpine. At lower elevations, monitor the overnight freeze of the snow surface. If the snow surface does not freeze overnight or if the crust is only a few cm thick, daytime heating or rain will weaken the snowpack much more quickly than if there is a well frozen thick crust. Low elevation and thin snowpack areas are likely to be isothermal.
Problems
Wet Slabs
Wet slabs could occur during warming. Glide slabs may also occur where the whole snowpack is sliding on a smooth ground surface, like rock slabs.
Be cautious in your terrain selection during periods of rain.>Avoid slopes with glide cracks.>
Aspects: All aspects.
Elevations: Alpine, Treeline.

Storm Slabs
Isolated storm slabs may be found at upper elevations.
Be cautious as you transition into wind affected terrain.>Choose well supported terrain without convexities.>
