Travel and Terrain Advice
The danger of glide cracks is increasing at lower elevations. Please stay away from cracked slopes and move quickly when passing below them. The danger of loose snow avalanches also increases with the degree of daytime temperature rise and rainfall. Wet snow is very heavy and easily scoots underfoot. If there is a "terrain trap" below you, the consequences can be grave. The weather is downhill and rainfall is forecast. Plan your activities with this in mind.
