In sintesi

While the forecast region hosts a primarily stable snowpack, a small risk remains of triggering a wet loose avalanche on steep solar lit aspects during the heat of the day. Observe for damp snow surfaces, roller balls, and recent avalanches, as these all indicate weakening snow surfaces. Adapt your travel techniques to meet the needs of the snow and terrain.    

Avalanche Discussion

Due to the consecutive lack of overnight refreezes, snow surfaces on southerly aspects near and above treeline have become very soft and mushy, making some snow surfaces unstable. Today, riders are most likely to encounter this problem on steep southerly slopes that receive direct sunlight for multiple hours of the day. While the size of a wet snow avalanche would remain relatively small, early season hazards and terrain traps drastically increase the consequences of being involved. Steep gullies, chutes, and slopes punctuated by rock outcroppings are terrain features to show caution towards. If you encounter wet, mushy snow that you can penetrate deeper than your boot cuff in, consider moving to a shadier aspect. Look for feedback in the form of roller balls, point releases, and recent avalanche activity to give you a better idea of what terrain to avoid. 

There have been little observations of wet loose snow instabilities over the past 72 hours, but we can't rule out the possibility given the inverted temperatures and wet, penetrable snow surfaces. Feedback from the snow illustrates this problem is slow to build momentum. Nevertheless, in the right terrain, at the right time of day, instability could occur. As in all cases, when snow is the problem, terrain is the solution.

While we wait for the Everitt Memorial Highway and Castle Lake Road to open, now is a perfect time to get out there with your partners and refresh those necessary skills of how to use a beacon, probe, and shovel.
