Lo esencial

Avalanches remain unlikely. Small wet snow instabilities may develop on steep, sunny slopes punctuated by rock outcroppings or large cliff bands during the heat of the day. Come prepared to arrest a fall, and watch for shedding ice and rock from the upper mountain.

    The forecast zone is about to be crashed on by a heat wave. The combination of warm temperatures, sunny skies, and high freezing levels will test the supportability of snow surfaces and increase the potential for wet snow instabilities.

    There is a small possibility for isolated pockets of snow to become wet and unstable today. Areas of greatest concern will be near heat conductors like rock outcroppings and cliff bands or in steep, protected bowls on solar slopes. 

    Exercise caution in high-consequence terrain and on slopes where snow can become funneled. Monitor for surfaces losing cohesion as daytime warming occurs and seek shadier or lower-angle terrain if you begin to sink past your ankles into mushy snow. Natural signs of instability—such as rollerballs and point releases—indicate this problem is gaining momentum. Give cornices a wide berth when traveling both above and below them.

Avalanche Discussion

It has been over a day since actively blowing snow was observed over the upper elevations of Mount Shasta. While small wind drifts remain unlikely, caution should still be used when traveling along prominent rocky ridgelines above 10,000 feet. Assess any wind-affected snow for shooting cracks as needed.

A well-consolidated and generally supportable snowpack has largely kept avalanche hazard at bay and provided excellent spring riding and climbing conditions. As the weather and snowpack warm, remain vigilant for overhead hazards, like falling rock and ice off the upper mountain. 

Spring conditions are dynamic—aspect and timing are key. Traveling earlier in the day while surfaces are firm and supportable can decrease your exposure to wet snow instabilities and increase your chances of finding quality riding conditions. Recent observations found the sweet spot for surface softening to be at 9,500 feet and below on sunny, protected slopes. Continue to carry a beacon, shovel, and probe whether you’re climbing, riding, or both. As always, stay alert for changing conditions and remain flexible with your route or objective if you observe signs of unstable snow. While it may feel like spring down low, it's still winter up high. And don't forget the sunscreen! 

Climbing conditions remain good. Surfaces above 10,000 feet are firm and not expected to soften. Falling can lead to a slide-for-life scenario. Carry a full mountaineering kit: 12‑point crampons (not microspikes), an ice axe, a helmet, and the skills to use them proficiently. Early‑season ascents are significantly riskier than a spring climb and demand a higher experience level.
