Travel and Terrain Advice
Note bonding of storm slab above crust. Beware of triggering in open areas with few trees and abrupt changes in slope. Beware of glide avalanches from open glide cracks at lower elevations where rainfall has been heavy, or from cliff-like terrain with thin snowpack. Do not enter the lower part of such slopes or pass through them quickly. When regrouping after skiing, please try to do so off avalanche terrain and in the safest place possible, such as on top of a ridge. The forecast is for clear skies during the day. Please be aware of the possibility of loose snow avalanches from large southerly steep slopes.
