Slightly increasing avalanche danger at high altitudes. Glide-snow avalanches persist.
Avalanche danger is moderate. On Tuesday night and during the day on Wednesday: snowfall and wind will increase danger somewhat. With ascending altitude and in high-alpine regions, fresh snowdrift accumulations and fresh snow will be prone to triggering, esp. in ridgeline terrain and in wind-loaded gullies and bowls. Easily triggerable! Danger of wet-anow avalnches will recede as temperatures drop. Glide-snow avalanches are still possible, esp. in starting zones where there is sufficient snow, releases can be large. Caution below glide cracks. Huge cornices still require caution.
Below 2500 m the old snowpack is thoroughly moist and wet down to the ground. The surface freezes at night depending on cloud cover and thus, nocturnal outgoing radiation often forms a melt-freeze crust. Tonight at high altitudes, uzp to 10-30 cm of fresh snow is possible, locally more. Amid gusty winds, fresh snowdrifts will be generated, moderately bonding with the snowpack.
Nocturnal hours: gray rainy skies, intermittently heavy snowfall down to below 1000 m. Wednesday daytime: Heavily overcast skies, light snowfall at above 1000-1400 m, tapering off in the afternoon, reduced visibility. At 2000 m: from -5 to -2 degrees. Light to moderate easterly winds.
Thursday will be sunny, much warmer during the course of the day. Winds will remain light. Due to solar radiation and higher temperatures, increasing loose-snow avalanches can be expected. Danger of dry-snow avalanches is not expected to change significantly. Glide-snow avalanches continue to be unpredictable.
