New snow will make for great skiing! Caution is advised as snow coverage over hazards such as rocks and trees may be thin. Snowpack variability will require careful assessment of every run. As always terrain management will be important.
Summary
Weather Forecast
Skies continue to clear, northerly winds and current cool temps will warm gradually for the next few days
Snowpack Summary
Recent storm snow continues to settle but the cold temps are slowing any formation of a surface slab except for specific southerly locations at or below tree line. The snow depths are variable and the recent storm snow overlies a variety of layers depending on aspect, elevation and shelter from the wind. Wind slabs continue to form.
Avalanche Summary
Several large avalanches were observed out of crossloaded alpine features. Numerous dry loose observed out of steep terrain
Confidence
Due to the number and quality of field observations on Monday
