With little re-freeze overnight and possible rain, conditions can change rapidly at lower elevations. Avalanche activity, snowballing, moist and wet snow are initial indicators of deterioration and increased hazard.

Sunday: A break between off-shore weather systems will bring overcast skies with a trace to light amounts of snow and some possible sunny breaks. Light south winds and 1500m freezing level.Monday: A weak ridge of high pressure starts to influence the weather pattern. Dry conditions and gradually rising freezing levels are forecast.
Avalanche Summary
Solar aspects have recently been very active showing lots of natural loose wet avalanches and cornice releases up to size 2.5 when the sun has been shining. Expect glide cracks to continue releasing with warm temperatures and rain at lower elevations.
Snowpack Summary
At upper elevations 20-30cm of new snow is covering a crust or moist snow. In some places in the alpine and at treeline this new snow may have buried a recently formed layer of surface hoar or facets. At lower elevations (below 2000m) rain has made the snow surface wet or moist down 50-100cm. New snow combined with wind will have made large cornices even bigger.
