- Red Flags Comment
- <p>At the end of each corn ripening cycle isolated Corn Slab Collapsing was experienced. As the frozen surface layers began to thaw, these slopes struggled to be supportable. As a result, there were Collapses observed on all sub 30 degree terrain traveled, and there was limited propagation due to shallow slope angles. </p> <p>The steeper landscape is littered with Loose Wet Avalanches and their debris. It appeared that many of these were from the last 48 hours; and I was able to hear one such Avalanche from the 8-Ball Area around 1200 hours. </p>
Overnight Lows may be at least 10 degrees warmer tonight, and the forecast for daytime highs on Thursday look to be at least 5 degrees warmer. Increasing cloud cover and rising RH values will only enhance the potential for these issues to be contributing factors of concern.
Snowpack
- Instability Comment
- <p>The majority of the activity observed was Wet Loose. Yet, exiting from the BC was done by 1330, and it was Likely that additional activity occurred in the excessive heat of the mid and late afternoon hours. Wet Slabs were a possibility; and the forecast for tonight and tomorrow Most Likely will increase the trend for this Avalanche Problem. </p> <p>Cornices and the potential for Glide Avalanches continue to be problems to consider and address with extreme caution. </p>
Rock hard refreeze at all altitudes. Refreeze ranging from 10 to 15 cm thick with wet grains below. Excellent corn riding with ripening on aspects as follows: East 0900-1000; SE 0930-1030; S 1000-1100; SW 1100-1200; W 1200-1300.
