Avalanche danger rising

Avalanche danger rising

As a result of snowfall, likelihood of slab avalanches triggering increasing, esp. in ridgline W/N/E facing slopes above 2200m. Avalanches can be triggered by persons and reach medium size. Caution urged in transitions from shallow to deeper snow in the regions where it is windy. Danger zones are difficult to recognize. Isolated whumpf noises can indicate imminent danger.

5-10cm of fresh snow is anticipated, locally more. Fresh snow and freshly generated snowdrifts lie deposited on W/N/W facing slopes above 2200m atop a weak old snowpack surface. The old snowpack is expansively metamorphosed with a loosely-packed surface of surface hoar and faceted crystals. South-facing slopes below 2000m: fresh snow and drifts are being deposited atop a crust.

Wednesday will be gray-skied, summits will be shrouded in clouds, frequent snowfall in morning hours will be widespread. In afternoon, snowfall will intensify. Light to moderate northerly winds will reach speeds of 45 km/hr, temperatures dropping from 4 to 1 degree at 1000m; from -2 to -4 degrees at 2000m: and from -7 to -11 degrees at 3000m. Snowfall level dropping from 1400m at midday down to 1000m in evening.
