January 31, 2014 at 7:00 Pockets of CONSIDERABLE avalanche danger may still exist on slopes steeper than 30 degrees in near and below treeline terrain on NW-N-NE aspects above 9000 ft. due to recent snow slabs sitting on top of persistent weak layers. Human triggered avalanches could remain likely on these slopes today. MODERATE avalanche danger exists on similar slopes on those aspects below 9000 ft. due to buried wet persistent weak layers. MODERATE avalanche danger also exists and on the wind loaded NW-N-NE-E-SE aspects steeper than 35 degrees in near and above treeline terrain due to the presence of wind slabs. The unusual conditions that exist in the mountains right now require extra caution and superb travel skills. |

February 1, 2014 at 6:57 Pockets of MODERATE avalanche danger exist at all elevations on NW-N-NE aspects on slope steeper than 32 degrees that held snowcover prior to the recent snowfall. For all other areas, avalanche danger is LOW. Persistent slabs and wet slabs remain an ongoing avalanche concern. |

February 6, 2014 at 7:00 MODERATE avalanche danger exists on slopes steeper than 35 degrees at all elevations on the NW-N-NE aspects and on near and above treeline E-SE aspects. A combination of wind slabs resting on weak snow, old persistent slabs, and loose snow sluffs represent the main avalanche problems today. Human triggered avalanches could be possible today. |

February 7, 2014 at 5:54 Areas of MODERATE avalanche danger will form today near and above treeline on the NW-N-NE-E-SE aspects on slopes 35 degrees and steeper as wind slabs continue to build. As higher intensity precipitation impacts the forecast area this evening through the overnight hours, avalanche danger is expected to increase to HIGH danger. |

February 10, 2014 at 7:00 CONSIDERABLE avalanche danger exists on slopes 32 degrees and steeper on all aspects above 7000 ft. due to wind slabs, storm slabs, and deep persistent slabs resting on a variety of weak layers. Below 7000 ft. where more of the storm's precipitation fell as rain, less avalanche danger exists. Even though the best window for natural avalanches has passed, human triggered avalanches remain likely today. Large, deep, and destructive avalanches could still occur today. |

February 11, 2014 at 7:00 MODERATE avalanche danger exists on slopes 35 degrees and steeper on all aspects in near and above treeline terrain due to wind slabs, the formation of loose wet snow, and unlikely but not impossible deep persistent slabs. MODERATE avalanche danger also exists below treeline on slopes 35 degrees and steeper on the SE-S-SW-W aspects due to the formation of loose wet snow. Although they are becoming more difficult to trigger, large, deep, and destructive avalanches could still occur today. |

April 18, 2014 at 7:00 Pockets of MODERATE danger will form on all aspects at all elevations on slopes 37 degrees and steeper as daytime warming and sunshine melt through the overnight refreeze that holds the snowpack together. Human triggered loose wet avalanches will become possible. Natural avalanches remain unlikely but not impossible. |

April 21, 2014 at 6:34 We have stopped issuing daily avalanche advisories for the 2013-2014 season as our funding allotted for this season is now exhausted. Avalanche advisories will resume in the fall of 2014. Avalanche activity can and most likely will continue to occur this spring as additional storm cycles impact the forecast area. Continue to monitor changing conditions and use caution when traveling in the backcountry. For general spring avalanche information please read the full spring avalanche statement. |

November 30, 2014 at 19:53 Early season conditions update #3. If the storms and snow accumulations forecasted for this week occur, the daily avalanche advisory will likely resume. For now and even after this weeks storms, expect early season conditions with lots of exposed rocks and a shallow weak snowpack that barely covers most obstacles. Keep checking this site for updates as the conditions change and the snow falls. |

December 3, 2014 at 6:55 Above 8,000', areas of CONSIDERABLE avalanche danger exist both above and below treeline on NW-N-NE-E-SE aspects on slopes 32 degrees and steeper. For all other areas, avalanche danger is MODERATE on slopes 35 degrees and steeper. Wind slabs and persistent slabs can be found in a variety of areas. Natural avalanches are possible, human triggered avalanches are possible to likely. |

December 4, 2014 at 7:25 Above 8000 ft. on slopes 32 degrees and steeper, human-triggered avalanches remain possible on NW-N-NE aspects in all terrain and on near and above treeline E-SE aspects. MODERATE avalanche danger exists in these areas due to wind slabs and possible persistent slabs. Higher elevation slopes with the most snow represent both the most dangerous places to go and the places where people want to recreate. Don't let early season excitement overrule good judgment and decision making. |

December 5, 2014 at 7:00 Above 9000 ft. on slopes 32 degrees and steeper, human-triggered avalanches remain possible on NW-N-NE aspects due to possible persistent slabs. Near and above treeline wind-loaded NW-N-NE-E-SE aspects above 8000 ft. steeper than 35 degrees may still hold human-triggerable wind slabs especially on unsupported slopes, couliors and gullies, and in complex and/or extreme terrain. The avalanche danger rating for these areas remains MODERATE. |

December 6, 2014 at 7:00 Above 9000 ft. in below, near, and above treeline terrain, human-triggered avalanches may remain possible on some NW-N-NE aspects due to persistent slabs on slopes 34 degrees and steeper. Pockets of MODERATE avalanche danger exist in these areas. Higher elevation northerly facing slopes with the most snow represent the most likely places to find persistent slabs and the places where people want to recreate. Don't let early season excitement overrule good judgment and decision making. |

December 7, 2014 at 6:56 Avalanche danger is LOW for all elevations and aspects. Low likelihood high consequence large size persistent slab avalanches remain a lingering concern in isolated areas above 9,000' on NW-N-NE aspects both above and below treeline. |

December 10, 2014 at 6:51 The avalanche danger will remain LOW for all elevations and aspects today. Continue to use normal caution when traveling in the backcountry. Expect the avalanche danger to increase dramatically starting tomorrow as a strong winter storm arrives over the forecast area. Wind slab, storm slab, and deep persistent slab avalanches could all become problems during this storm. |

December 11, 2014 at 6:54 The avalanche danger will remain LOW until the precipitation starts to fall. Once the snow begins accumulating the avalanche danger will increase quickly and could reach HIGH on slopes steeper than 32 degrees during the night. Natural avalanches will become likely tonight and early tomorrow morning. Wind slab, storm slab, and deep persistent slab avalanches will all become problems during the next 24 hours. Travel in and around avalanche terrain is not recommended during the storm. |

December 12, 2014 at 7:00 Human-triggered avalanches are likely (CONSIDERABLE danger) on NW-N-NE aspects steeper than 32 degrees due to wind slabs (all elevations) and deep persistent slabs (above 9000 ft). In other wind loaded areas on NW-N-NE-E-SE aspects human triggered avalanches will be possible (MODERATE danger) on slopes 35 degrees and steeper. Strong winds may mean wind slabs formed at lower elevations and in atypical areas. In areas east of Lake Tahoe where less snow fell, less avalanche danger will exist. |

December 13, 2014 at 6:54 Near and above treeline, pockets of MODERATE danger exist along the Sierra Crest on NW-N-NE-E-SE aspects on slopes 35 degrees and steeper due to lingering wind slabs. For all other areas, avalanche danger is LOW. |

December 15, 2014 at 6:48 Isolated pockets of MODERATE avalanche danger may form today near and above treeline on NW-N-NE aspects on slopes 35 degrees and steeper. For all other areas, avalanche danger is LOW. Isolated areas of small and shallow wind slab instability are expected today in wind loaded areas. |

December 16, 2014 at 6:51 Human-triggered wind slab avalanches are possible (MODERATE avalanche danger) on wind-loaded NW-N-NE-E aspects 35 degrees and steeper in near and above treeline terrain. Due to shifting winds some isolated pockets of wind slabs may exist on SE aspects in near and above treeline terrain. Use clues like cornices, drifted snow, ripples in the snow surface, and other wind created textures to help determine where wind slabs may exist. |
