Avalanche Summary
No new avalanche activity has been reported.
If you are out in the backcountry please consider filling out a Mountain Information Network report.
Snowpack Summary
On the surface, a supportive melt-freeze crust exists on most aspects and elevations, on northerly, sheltered terrain the crust is reported to be breaking down. There are reports of the presence of surface hoar on top of this crust. The crust ranges from roughly 1 to 10 cm. Below the surface crust, the snowpack is moist and generally well settled and bonding, with no current layers of concern.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
- Wind slabs may be poorly bonded to the underlying crust.
Problems
Wind Slabs
Moderate amounts of new snow are forecast to fall with southerly winds. This could result in wind slabs that are poorly bonded to the old crusts and hard surfaces beneath. Approach any slope with more than 20cm of new snow on it with caution.
