Moderate
Avalanche Summary
Heavy snowfall and strong wind on Saturday are expected to form large storm slabs that are very reactive to human triggers.
Observations are limited at this time of year, please consider sharing any information or photos you have on the Mountain Information Network to help guide our forecasts.
Snowpack Summary
Forecast intense snow and wind are expected to form large and reactive storm slabs.
Below the new snow, a melt-freeze crust likely exists on all aspects below 1400 m.
The middle and lower snowpack are strong and well-bonded.

Terrain and Travel Advice
- Avoid all avalanche terrain during periods of heavy loading from new snow, wind, or rain.
- Avoid exposure to overhead avalanche terrain, avalanches may run surprisingly far.
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Use small low consequence slopes to test the bond of the new snow.
