Southern San Juan

A potent winter storm is entering Colorado on a southwest flow. Parts of the forecast area could see up to two feet of snow by Saturday morning. Avalanche danger and the size of the avalanche you can trigger will increase throughout the storm. Above treeline, northerly-facing slopes that harbor old snow are the most dangerous. Cracking and collapsing are obvious signs of instability and likely indicate you are on a slope where old/weak snow sits above the ground.

Sticking to slopes that didn't have snow before this storm or slopes less than about 32 degrees is a good way to keep yourself safe from avalanches.
