March 8, 2017 at 7:00 The avalanche danger is MODERATE above 5000 feet. More snow and moderate to strong winds today will continue to form wind slabs making it possible to trigger an avalanche on wind loaded slopes. Be cautious of all wind-loaded terrain today. Carefully evaluate the conditions before committing to a slope. Below 5000 feet the danger is LOW. Identify and avoid features of concern. |

March 2, 2017 at 7:00 Warming temperatures, strong winds, and relatively heavy snow created dangerous conditions. The avalanche danger is CONSIDERABLE above 5000 feet, and human triggered avalanches are likely. Continued warming and additional snowfall today will cause sensitive storm slabs to become more widespread as the day progresses. Below 5000 feet where human triggered avalanches remain possible the danger is MODERATE. |
