Avalanche Summary
On Friday a natural avalanche cycle up to size 3 took place in the south west corner of the forecast region. These avalanches failed on the late January crust.
If you are out in the backcountry please consider filling out a Mountain Information Network report.
Snowpack Summary
Ongoing snowfall and southwest winds have accumulated around 40 cm of storm snow that is being blown into wind slabs. This all sits on a crust from the warming event on January 25th. New snow likely will not bond well to this crust.
The mid and lower snowpack continues to bond and stabilize. A few concerning weak layers can still be found in the top meter of the snowpack including a surface hoar layer from early January and a crust from late December.

Terrain and Travel Advice
- Watch for changing conditions today, storm slabs may become increasingly reactive.
- Dial back your terrain choices if you are seeing more than 20 cm of new snow.
- Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
