Highlights

The avalanche danger will increase from Low this morning to Moderate in the afternoon as warm temperatures and morning sunshine weaken snow surfaces. The likelihood of human-triggered or natural wet avalanche activity will increase as this weakening occurs. Avoid being in or under large, steep, sunny slopes during the afternoon. Continue to give cornices a wide margin.

    No overnight freeze and continued warm and sunny conditions this morning will destabilize snow surfaces by the afternoon. Increasing cloud cover and wind arriving this afternoon will help slow this process, but may not arrive in time to make a big difference. Human-triggered wet loose avalanches will be possible in very steep terrain. Natural avalanche activity is less likely. Wet snow avalanches will generally be on the smaller side, but some could entrain enough snow to bury or injure a person. 

    Monitor the snow surface as the day warms. Sinking deeply into wet, slushy snow is a good indicator that conditions are becoming unstable, and it is time to move away from steep terrain. An early start and exit from the mountains are the best ways to manage wet snow problems today.

    Terrain like this could produce a sizeable wet avalanche this afternoon.

     

Avalanche Discussion

Warm temperatures continue today. Overnight low temperatures remained above freezing in many locations. Daytime high temperatures will be similar to yesterday before clouds increase this afternoon and winds pick up. The incoming cold front will most likely not arrive in time to appreciably change conditions during the day, although gusty westerly winds this afternoon will help keep surfaces cooler.  Loose avalanches involving wet snow near the surface should continue to stay on the radar even with the incoming system.

Timing the transition from hard refrozen snow to snow that is just beginning to soften will be the key to good riding with stable conditions. With a weak overnight freeze, this time window becomes even more critical. Avoid lingering under very steep and rocky avalanche paths late in the day, and continue to give cornices a wide berth as they will be more likely to fail in the heat of the day.

Human Factor 2.0 Backcountry Recreation Survey: For years, the avalanche community has worked to understand and address the human factors that influence decision-making in the backcountry.  A current project involves interviewing backcountry recreationalists traveling in avalanche terrain for at least one season. All participants will be entered to win some great raffle prizes (from Jones Snowboards, BCA, and more!).

Please consider taking 1-2 minutes to fill out our basic initial survey.
