Avalanche Forecast
Regions: Coquihalla, Harrison-Fraser, Manning, Skagit.
Freshly formed storm slabs will be most reactive in wind affected terrain.
Use small low consequence slopes to test the bond of the new snow.
Confidence
Low
Avalanche Summary
Forecast snow and wind Monday night will likely form storm slabs reactive to human triggers on Tuesday.
If you go into the backcountry, please consider submitting your observations to the Mountain Information Network.
Snowpack Summary
15 to 25 cm forecast snow and wind will form storm slabs that will likely be reactive to human triggers on Tuesday.
Below the new snow is a crust everywhere except true north facing terrain at upper elevations.
Many areas below treeline are either snow free or have very thin snow coverage. Expect difficult travel at lower elevations.

Terrain and Travel Advice
- Choose conservative terrain and watch for clues of instability.
- Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
- Be especially cautious as you transition into wind affected terrain.
- Use small low consequence slopes to test the bond of the new snow.
