Skiers and Riders continue to trigger wind slabs and Cornices in the Alpine! Click here to access the Mountain Information Network for more details.
Strong winds deposited wind slabs in isolated areas on all asp. On Monday a skier accidental size 1 occurred on a North asp in the Alp. Tuesday several skier controlled slabs size 1 in the ravens and on Wed a skier remote size 1 near the Asulkan.
Cornices are LARGE this time of year and becoming brittle with cold temperatures. On Wednesday skiers did some cornice control on Mt Bonney, the large cornice did not pull a slab on the slope but the cornice itself was a size 3 avalanche!
Cold clear air from the North continues to dominate the weather over Rogers Pass. On Thursday expect an Alpine high of -9, light winds from the E, and no precipitation. No real changes on Friday, and we might see a trace of new snow on Sat. No major changes in the short term. Long term we are expecting a gradual warming trend with flurries.
Widespread wind effect in the Alpine and upper treeline has left behind wind slabs on specific terrain features, and scoured the new snow away in others; however, there are still reports of decent conditions in the Alpine in sheltered zones. At Treeline and below the spring snowpack currently has a solid supportive melt-freeze crust.
No new avalanches in the HWY corridor. A close call occurred on Monday, where a small pocket of wind slab nearly took a skier into a crevasse! Click the link here for the full report. On Tuesday several human-triggered size 1 wind slabs occurred on the Ravens. And on Wednesday skiers did some cornice control and triggered a size 3 off of Mt Bonney!
