Travel and Terrain Advice
At higher elevations, please keep an eye on fresh snow conditions up to this morning. Be alert for "terrain traps" where even small avalanches can have serious consequences. Warm southerly winds are expected to enter the area and significant temperature increases are also forecast, so please pay close attention to weather changes during the day. At higher elevations, elevated temperatures and winds may cause slabs to form quickly and instability to appear. At lower elevations, there is a risk of glide avalanche. Do not enter slopes with glide cracks and move quickly when passing under them.
