Summary
Weather Forecast
A trace of new snow, light NW winds and alpine temperatures of -18C are in the forecast for today. More of the same for Tuesday too.
Snowpack Summary
Daily small inputs of snow along with moderate winds have formed thin reactive surface slabs along the immediate lee of ridges and cross loaded features. If triggered these slides will likely be small, size 1 slides but should not be discounted. Below the surface snow are widespread hard slabs formed when the arctic air pushed into our region.
Avalanche Summary
No new avalanche activity observed in the highway corridor in the last 24hrs.
Confidence
The weather pattern is stable
Problems
Wind Slabs
Thin, fresh, soft windslab resides on top of hard slab formed when arctic air moved in. Depending on location the hard slab may be just at ridge top or extend further down slope.
Use caution in lee areas. Recent wind loading has created wind slabs.The recent snow may now be hiding windslabs that were easily visible before the snow fell.
