January 5, 2016 at 7:00 The avalanche danger is MODERATE above 6000 feet and human triggered avalanches are possible. Wind slabs of varying age exist across the advisory area. Some have had a chance to gain strength. Other more recently formed slabs will still be weak. Carefully evaluate the snowpack before committing to a slope, particularly in steep, wind loaded terrain. The danger is LOW below 6000 feet and normal safe travel practices should be used.

January 3, 2016 at 7:00 Variable winds over the past few days transported recent snow and created windslabs on multiple aspects. The avalanche danger is MODERATE above 5000 feet and human triggered avalanches are possible. Carefully evaluate the snowpack before committing to a slope, particularly in recently wind loaded terrain. The danger is LOW below 5000 feet.

January 2, 2016 at 7:00 Recent winds, continued sunshine, and temperatures approaching the freezing mark will continue to form more cohesive slabs in previously unconsolidated surface snow. The avalanche danger above 5000 feet is MODERATE and human triggered avalanches are possible. Below 5000 feet the danger is LOW. Carefully evaluate the snowpack before committing to a slope, particularly in recently wind loaded terrain. Pay attention to rising temperatures and the effect of sun exposure on the surface snow. |

January 1, 2016 at 6:59 Happy New Year! The danger above 5000 feet is MODERATE and human triggered avalanches are possible. Recent wind loading, warming, and ample sunshine will cause stability to change. Wind slabs, soft slabs, and natural, sun initiated sluffs will be possible today. Treat recently wind loaded terrain as suspect and carefully evaluate the snowpack and terrain before committing to any slope. Pay attention to the effects of warming (potentially above freezing) on the snowpack. Below 5000 feet the danger is LOW. |

December 31, 2015 at 7:00 The avalanche danger above 6000 feet on steep wind-loaded terrain is MODERATE and human triggered avalanches are possible. On all other slopes the avalanche danger is LOW. Remember, LOW danger does not mean NO danger. An avalanche can still be triggered during periods of LOW danger. Treat recently wind loaded terrain as suspect and carefully evaluate the snowpack and terrain before committing to any slope. Continue to use proper travel techniques in avalanche terrain. |

December 28, 2015 at 7:01 The avalanche danger above 6000 feet is CONSIDERABLE on wind loaded slopes steeper than 35º. Elsewhere, the danger is MODERATE. In select areas of our advisory area recent winds have been strong enough to drift the light, cohesionless surface snow and form new wind slabs on leeward ridges, and cross-load mid slope features. Carefully evaluate wind loaded terrain today before skiing or riding a slope. |

December 26, 2015 at 7:00 The Swan Range picked up over 5 inches of snow water equivalent in the last 5 days. Dangerous avalanche conditions continue today. The avalanche danger is CONSIDERABLE at all elevations. Human triggered avalanches are likely and natural avalanches remain possible. Carefully evaluate the snowpack and make conservative decisions in the backcountry today. See advisory for other ranges here. |

December 26, 2015 at 7:00 The avalanche danger above 5000 feet is CONSIDERABLE on slopes steeper than 35º and MODERATE elsewhere. Continue to carefully evaluate the snowpack and choose conservative terrain. Due to lingering storm and wind slab instability human triggered avalanches are likely on steep slopes today.
