ross campbell,
Exercise extra caution if the sun comes out this afternoon, especially on steep solar aspects.
Summary
Weather Forecast
A mix of sun and cloud today; starting cloudy, then the sun will try and poke through, as a ridge of High-Pressure starts to build over Rogers Pass. The FL is expected to reach 1600m, an Alpine high of -4, and light winds from the SW. Tomorrow the ridge will settle over us, bringing sunny skies and warm temperatures. The FL will reach 2100m!
Snowpack Summary
Recent strong to extreme winds have left behind a variety of wind slabs in the Alpine and exposed areas of TL. In sheltered areas at and below TL the snowpack is generally "right side up" with decent riding conditions. The February drought layer is buried ~1m, and the Jan 24th layer is down ~1.4m; both layers have been unreactive in snowpack tests.
Avalanche Summary
Minimal avalanche activity has been noted recently. Reports of skier controlled size 1 wind slabs yesterday in the Avalanche Crest WRA, and Ursus Trees. MCR report of an audible off of Mt Bonney, likely a cornice. Expect wind slabs in the Alpine and exposed areas of TL; caution in steep unsupported terrain features where the snowpack is shallow.
Confidence
Problems
Wind Slabs
Previous extreme winds have left behind variable surface conditions, and wind slabs in the Alpine and exposed areas of Treeline. There is a moderate amount of uncertainty in the Alpine, with limited observations due to weather and visibility.
- Watch for shooting cracks or stiffer feeling snow. Avoid areas that appear wind loaded.
- Use caution in lee areas. Recent wind loading has created wind slabs.
Aspects: All aspects.
