In sintesi

Winter will make an appearance once again. Cold temperatures and up to 20+ cm of snow on Tuesday. If you do get skiing, be cautious of the sluffing in steeper terrain as the snow will likely not bond well with the colder temps

Terrain and Travel Advice

  • Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
