Prepare for winter conditions, ice and snow-depths from 8 to 18 inches by the end of the weekend, with the deepest snows at higher elevations. Snowshoes and ice crampons and traction devices are recommended if you are headed to the High Peaks this weekend. Temperatures will reach into the teens on summits, with wind chills mostly in the single digits below zero on summits this weekend. Some stream crossings may be difficult. Some ice has been forming, but no ice should be considered safe.
