Fair - Due to the number of field observations

Expect warm and mainly dry weather until late Monday, with the freezing level around 2800 m. Light precipitation begins early Tuesday, before a Pacific  disturbance brings up to 15 mm precipitation on Wednesday/Thursday. The freezing level is expected to be near 800 m through the storm.  Winds are moderate to strong south-westerly on Monday, before switching to north-westerlies.

Naturally-triggered size 2 slabs were observed within recent storm snow in the north of the region. Cornices also failed on Friday. Avalanche danger is expected to be lower in the cool parts of the day, and rise during warm, sunny periods. As temperatures rise, also keep in mind the possibility of glide slabs releasing on smooth rock surfaces - avoid traveling on or under slopes sporting glide cracks.

In general, the snowpack is strong, but may weaken during peak warming periods. Cornices may fail with warm temperatures. Wind slabs may be found in the alpine. On steep, sunny slopes, it is likely that soft, moist snow will develop by day, and crusts may form at night. Below treeline, the snowpack is generally strong and uniform. A layer of surface hoar buried in the upper snowpack has been reported in some areas, and is worth investigating before committing to any big alpine terrain. In general, the mid and lower snowpack are strong and well-settled. At the base of the snowpack, weak facets may be found. Smooth rock slabs may act as a sliding surface for the entire snowpack to glide on in specific locations as temperatures rise.
