Southern San Juan

Modest snowfall and moderate winds arrive early Wednesday morning. Anticipate changing avalanche conditions with the arrival of new snow. You could trigger an avalanche where winds drift new snow onto leeward slopes at upper elevations. Avalanches will be larger, where you find more than about six inches of new snow.

Signs of instability include cracking or easily triggered loose avalanches in the new snow. If you see these signs, consider moving to lower elevation slopes less than 35 degrees steep.
