Kernpunkte

On Friday, be prepared to address both dry and wet loose avalanche concerns, particularly in steep terrain. A strong, supportive crust near the surface has effectively stabilized the majority of the snowpack. However, there's a layer of storm snow ranging from 5 to 12 inches atop this crust. While the storm snow remains light and dry at higher elevations (5500 ft and above), it has transitioned to a wet consistency at mid and lower elevations. To mitigate the risk of triggering dry or wet loose avalanches, steer clear of slopes exceeding 35 degrees.

    Yesterday, we found approximately 12 inches of soft snow at elevations exceeding 5,500 feet. Over the past week, intermittent weather bursts have deposited a few inches of snow at a time, accumulating between 5 and 14 inches. The Cabinet Mountains received marginally more snow compared to the Selkirks.

    The recent storm snow, resting atop a sturdy, supportive crust, exhibited no indications of instability. Even near ridgelines, cohesive wind slabs were absent, and there were no observable signs of instability.

    Springtime conditions are subject to rapid change, so maintaining awareness of evolving conditions is important. Should the dry snow transition to a wetter, more cohesive slab, the risk of avalanches may escalate. Be vigilant for pinwheeling, shooting cracks, and minor point releases, as these could signify changing conditions.

    Welcome to springtime! With the changing conditions throughout the day, the likelihood of wet loose avalanches increases as temperatures rise. Keep an eye out for rollerballs, pinwheels, or natural wet loose avalanches, as these serve as indicators to exercise caution and opt for lower slope angles, making deliberate terrain selections.

    While most avalanches may remain small, they could still pose significant risks by potentially sweeping you into terrain traps like trees, rocks, or creek beds. Stay vigilant of evolving conditions and consider riding or skiing when the snowpack surface isn't saturated and remains firm.

Avalanche Discussion

Starting Saturday, expect rising temperatures and plenty of sunshine! Stay vigilant and keep a close watch on changing conditions. Typically, it's good to head out on your adventures earlier in the day during periods of sunshine. You'll want to beat the rapid warm up as the sun beats down and temperatures rise.

A big thank you to all our IPAC supporters and those who provided observations. Observations play a crucial role in understanding backcountry conditions. Despite the chirping birds and burgeoning grass, there's still plenty of snow in the high country. Make the most of it before it melts away! While summer activities like tennis and biking await, seize the opportunity to indulge in some skiing or riding while you still can. You'll be glad you did!

**This marks our final avalanche forecast of the season, but we'll continue to monitor the weather and snowpack, providing information as necessary.

Take care and stay safe out there!
