In sintesi

While unlikely, small wet loose avalanches are not impossible today. Remain cautious on steep solar aspects, especially around rocky areas. If you find yourself sinking into unconsolidated wet snow past your ankles or encounter a layer of greasy snow atop a crust, consider changing aspects or moving to gentler terrain. If climbing, come prepared to arrest a fall and be mindful of overhead hazards. Anticipate the potential for thunderstorms and have a plan to be off of exposed areas before they develop.

    Any wet snow instabilities that develop are most probable on steep solar aspects around rock outcroppings. Warm temperatures and continued above freezing nights may increase the chances of finding unstable snow. Ankle-deep boot penetration or greater into wet, unconsolidated snow or weak, wet snow that sluffs easily on top of a crust should direct you to gentler terrain or colder aspects. Travelling early will help reduce your exposure to the instability. While any resulting avalanche would be small, the consequences of being caught in extreme terrain are the greater hazard. Continue to give cornices a wide margin when traveling above and below them.

    A small wet loose avalanche that occurred last month in Powder Bowl. The slide was likely triggered by rockfall and ran approximately 200 feet. This is the type of extreme, isolated terrain near rock features to exercise caution around.

Avalanche Discussion

Afternoon and evening thunderstorms are a notable feature of today's weather forecast with the pattern continuing at least through the end of the week. Expect building cumulus through the day and remember thunderheads can develop quickly, especially over higher terrain and Mount Shasta. It's up to you to make your own assessment of the weather and how conditions are developing. 

Climbing: Aside from weather, other notable hazards include icefall, rockfall, and firm, icy surfaces with slide-for-life potential.  A full mountaineering kit is non‑negotiable: 12‑point crampons (not microspikes), an ice axe, a helmet, and the skills to use them well. We can't stress it enough. Be prepared and know how to use your equipment. Have the courage to turn around if the weather, your skills, or anything else just doesn't feel right. The mountain will be there next time. Managing risk means recognizing and correcting small issues early, before they compound into a situation with serious consequences. Obstacles continue to melt out at lower elevations and present an additional hazard, especially for skiers. Feel free to give us a call if you have questions about your trip - 530-926-9614. 

Due to rain in the forecast for this weekend, the end of season party on Saturday has been moved from Native Grounds to Mountain Medics at 2600 Spring Hill Road. Doors open at 4:00 pm. We look forward to seeing you all there!
