Advisory – Past Fifteen Days

Avalanche Advisory for Monday, January 23, 2016

Water in the snowpack appears to be refrozen at most elevations and aspects on the mountain. As a result of this refreeze, the probability of Loose-Wet and Wet Slab avalanches will continue to decrease. One factor that is hard to pin down is the cloud cover forecast. On sunny aspects, the refreeze may slow or even reverse; be vigilant about snowpack evaluation as you venture onto steeper sunny slopes later today.

Avalanche Advisory for Sunday, January 22, 2017

Due to the slow refreeze occurring on the mountain right now there is unlikely to be much of a loose-wet or wet slab avalanche problem remaining. There is a warm band of air remaining at around 5,000’ feet so look for warm and potentially unstable snow in any area that has not refrozen yet. A potentially greater problem today will be the difficult travel conditions due to post-holing through the breakable crust combined with the potential for a long fall on a hard snow surface.

Avalanche Advisory for Saturday, January 21, 2017

With another warm day ahead of us, Wet Slab and Loose-Wet avalanches will be on our radar. Warm air temperatures and sunshine may test our snowpack today. There are two areas of new snow that present the most concern. The first of these is the areas of wind loading that occurred on Wednesday night and Thursday. These wind slabs formed on WNW winds and are largely in lee areas of our steepest terrain. The second layer of new snow presenting a concern is the areas of sluff deposit. Again, primarily under the steepest terrain, these two layers of new snow may see a strong period of warmth today that could test their bond with the old surface or soft snow interfaces underneath.

Avalanche Advisory for Friday, January 20, 2017

Wet slabs and loose-wet avalanches will compete for your attention as today. Rising temperatures through the night coupled with sunshine, light winds and warm air temperatures will reduce the strength of our snowpack through the day. Areas of greatest concern are the fan shaped deposits of sluff debris that exist beneath steep terrain in the most easterly facing aspects and beneath steep pitches. These areas as well as large expanses of yesterday’s wind slabs will be capable of producing the largest avalanches.

Avalanche Advisory for January 19, 2017

This advisory expires at Midnight. Huntington Ravine has CONSIDERABLE and MODERATE avalanche danger. Yale, Central, Pinnacle, and Odell have Considerable avalanche danger. Natural avalanches are possible and human-triggered avalanches are likely. North, Damnation, South and Escape Hatch have Moderate avalanche danger. Natural avalanches are unlikely and human-triggered avalanches are possible.  Tuckerman Ravine has CONSIDERABLE and […]

Avalanche Advisory for Wednesday, January 18, 2017

The primary avalanche problem will be Dry Loose avalanches. Soft Wind Slab may also develop behind terrain features and near the tops of gullies.

Avalache Advisory for Tuesday, January 17, 2017

  This advisory expires at midnight. Tuckerman and Huntington Ravine have LOW avalanche danger. All forecast areas have Low avalanche danger. Natural and human-triggered avalanches are unlikely. In Tuckerman Ravine, Lower Snowfields and Little Headwall are not rated due to thin snow cover. AVALANCHE PROBLEM: The current avalanche problem is Wind Slab that formed Sunday. […]

Avalanche Advisory for Monday, January 16, 2016

Tuckerman and Huntington Ravine have LOW avalanche danger. All forecast areas have Low avalanche danger. Natural and human-triggered avalanches are unlikely. In Tuckerman Ravine, Lower Snowfields and Little Headwall are not rated due to thin snow cover. AVALANCHE PROBLEM: Recent rain and a solid refreeze has reduced our avalanche problem to the scattered wind slabs […]

Avalanche Advisory for Sunday, January 15, 2017

Thin Wind Slab will form today in isolated pockets. While likely small in size, scattered, and easy to identify when compared to the old surface, they could be enough to knock someone off their feet, leading to the big hazard today: long, sliding falls… A busy holiday weekend will lead to many people on the mountain today. Be prepared for routes to be crowded and to have to decide whether to wait in line or choose a different goal for the day.

Avalanche Advisory for Saturday, January 14, 2017

This advisory expires at Midnight. Tuckerman and Huntington Ravine have LOW avalanche danger. All forecast areas have Low avalanche danger. Natural and human-triggered avalanches are unlikely. In Tuckerman Ravine, Lower Snowfields and Little Headwall are not rated due to thin snow cover. AVALANCHE PROBLEM: Recent rainfall has penetrated into our snowpack and created hard surface […]

Avalanche Advisory for Friday, January 13, 2017

This advisory expires at Midnight. Tuckerman Ravine has MODERATE and LOW avalanche danger. Sluice, Lip, Center Bowl and Chute have Moderate avalanche danger. Natural avalanches are unlikely and human-triggered avalanches are possible. All other forecast areas have Low avalanche danger. Lower Snowfields and Little Headwall are not rated due to thin snow cover.  Huntington Ravines […]

Avalanche Advisory for Thursday, January 12, 2016

This advisory expires at Midnight. Huntington and Tuckerman Ravines have CONSIDERABLE avalanche danger. All forecast areas will have Considerable avalanche danger today. Natural avalanches are possible and human-triggered avalanches are likely. Dangerous avalanche conditions exist. Careful snowpack evaluation, cautious route-finding and conservative decision making are essential.  Lower Snowfields and Little Headwall are not rated due to […]

Avalanche Advisory for Wednesday, January 11, 2017

New snow last night with strong, shifting winds today will create large wind slab in all areas. These new slabs will see increasing loads throughout the day and with well-developed avalanche paths, they have the potential to run far. The terrain above Connection Cache in Tuckerman and the Fan in Huntington is avalanche terrain – don’t be lulled into a false sense of security. While there are areas that could be traveled in, with careful snowpack evaluation and cautious route-finding, good conservative decision making may lead to not traveling in avalanche terrain today.

Avalanche Advisory for Tuesday, January 10, 2017

This advisory expires at midnight. All forecast areas of Huntington and Tuckerman Ravine have LOW avalanche danger. Natural avalanches and human-triggered avalanches are unlikely. Watch for unstable snow on isolated terrain features. Lower Snowfields and Little Headwall are not rated due to a lack of snow but look for overhead hazard in Lower Snowfields which remains […]

Avalanche Advisory for Monday, January 9, 2017

This advisory expires at Midnight. Huntington and Tuckerman Ravine have LOW avalanche danger. All forecast areas have Low avalanche danger today. Natural avalanches and human-triggered avalanches are unlikely. Watch for unstable snow on isolated terrain features.  Lower Snowfields and Little Headwall are not rated due to a lack of snow but look for overhead hazard […]
