Problemi valanghivi
Weather Synopsis
On Monday it will be sunny, but very windy. An icy NW wind will reach 40-60 km/hr. At 2000 m: -10 degrees, at 3000 m: -16 degrees. On Tuesday, heavy cloud cover will move in, snowfall is anticipated and a strong NW wind will be blowing, enough to transport the snow. Ongoingly cold.
Tendency
Little change. Wind-loaded leeward slopes and gullies remain treacherous.
Avalanche Activity
Strong NW winds, instable drifts in gullies and on leeward slopes
Avalanche danger below the timberline is LOW, at forest edges and above that altitude danger is CONSIDERABLE. Potential danger zones are focused on wind-loaded gullies lying immediately adjacent to windblown zones; and on leeward steep slopes, also at forest edges. This applies particularly to NE/E/S/SW aspects where the freshly generated snowdrift accumulations can easily be triggered. Medium, some large-sized slabs are possible.
Snowpack Structure
Fresh snow (20-30 cm) loosely-packed and very cold, was transported by northerly winds, deposited in gullies and on leeward slopes. Exposed terrain is often windblown. The snowdrift accumulations are wide-ranging in places, deposited on loose and cold snow - easily triggered.
