Marcus Waring,
The wind effected upper snowpack will be stressed by rapid warming caused by a strong temperature inversion in our area. Be mindful of your overhead hazard if you plan on venturing into the backcounty this weekend.
Summary
Weather Forecast
Alpine temperature inversion will be prevalent throughout the forecast period.

Snowpack Summary
Wind transport has scoured SW aspects to ground in exposed alpine terrain. Northerly aspects & protected areas have wind slab 5-40cm thick over a melt freeze crust. Lower snowpack is beginning to facet below this crust.
Snowpack @ 2000m: Cameron Lake 80cm. Less than 30cm in rest of park. Below tree line elevation is under threshold snowpack height.
Avalanche Summary
No new avalanches observed.
Confidence
Problems
