Kernpunkte

Throughout the forecast region, generally safe avalanche conditions exist. The primary concern will be increasing wet loose snow instabilities on steep solar-lit slopes in sheltered areas. Point releases and roller balls are precursors to wet loose avalanche activity. Move aspects and be off of extreme terrain early to avoid this problem. Overhead hazards, such as cornice collapse and rockfall, are becoming more of a threat. Remain vigilant near these features, as there's no telling when they might decide to release.

    Solar-lit slopes near and above treeline that hold soft surface snow, or weak surface crusts, will be the first and most susceptible areas to warming. Today's fair weather will allow this problem to build momentum. Riders will be most at risk on steep, sheltered slopes that face the sun or in extreme terrain among rock outcroppings. These locations are where heightened avalanche danger exists and will be most prevalent in the mid to late afternoon. Any wet loose activity is likely to be relatively small in size (D1 or less) due to the shallow and variable amounts of surface snow. A hard, widespread underlying crust will act not only as a bed surface but also as a protective layer, deterring snow from gouging deeper. Signs of warming will begin with roller balls and point releases. If you see these occurring on representative aspects, take note and assume the potential for wet loose activity. Start early, micromanage your aspect choice, and identify terrain traps to maximize your safety margins.

    Wahrscheinlichkeit
    Possible
    Größe
    1–1.5

    Large cornices adorn many ridgelines and predominantly overhang leeward west, north, and east facing slopes. The Castle Lake area is at heightened risk for cornice fall. A very large cornice overhangs the ridgeline above Heart Lake. Several large cornice chunks have already realeased and tumbled down to areas some would believe to be “safe." They are not. Travelers should avoid going near or beneath this feature in the days to come. This zone certainly has a lot to offer: easy access, beautiful views, and supportable conditions. Enjoy it, but don't let your guard down or underestimate the severity of this hazard.

Avalanche Discussion

Yesterday, forecasters experienced tranquil conditions on the home dome. Find out more HERE. Spring has sprung, and Mount Shasta is set up for a superb spring ski and climbing season. However, we're still in the preliminary phase. As this transition occurs, it's a great opportunity to reflect on changes you may have experienced as a backcountry recreationalist this season. The one constant we have in this life is change. Change brings experience, experience brings knowledge, and knowledge builds judgment. What you observe in the backcountry (or life) becomes your knowledge, and your knowledge guides your judgment. It's a re-circulating pattern. So, how have your observations and experiences this winter influenced your knowledge? And how will that knowledge transfer to your judgment? Thus, how has your experienced based judgment changed? If at all. Food for thought on how you want to perform in the mountains as we transition into a more technical season with higher risk tolerances, mental states, and hazard types. “Developing judgment lies not in the regurgitating of facts, but in the reasoning behind the action.” April 14th will be our last daily forecast for the season.  To celebrate an excellent season, please join us for our Community and Member Appreciation Party where we will have FREE food, drinks, and live music!
