Weather Forecast

Avalanche Summary

A few small slab avalanches (Size 1.0 to 1.5) have been reported to office in past 48hrs. These have been mostly 10 to 30cm thick wind slabs and have been either ski-cuts or natural triggered on steep E and NE aspects.Two size 1.0 loose dry avalanches were reported to flow over the ice climb "Amadeus" in the front ranges earlier today. Though not large, these slides would have been enough to know a climber off of their stance.

Snowpack Summary

Surface facetting. Some snow transport at ridgetop due to strong winds. Variable wind slab in Alpine. October rain crust down 50 to 70cm in Alpine. Below treeline remains below threshold.
