Localized Avalanche Hazard
Forecasted Weather Influences
Overnight a few light snow showers are expected mainly above 850 metres with North-Westerly winds. During the day, more light passing snow showers will occur above 800 metres with strengthening North-Westerly winds.
Forecasted Snow Stability and Avalanche Hazard
New snow amounts are not expected to be significant but in the snow showers the strong North-Westerly winds will form localised pockets of windslab in sheltered locations. The greatest accumulations will be above 850 metres on East through South to South-West aspects. Steep slopes, sheltered gullies and scarp slopes will be particularly effected. The avalanche hazard will be Moderate.
Observed Avalanche Hazard - Fri 12/03/2010
Observed Weather Influences
Overnight, light snow showers occurred above 950 metres with North-Westerly winds and a the freezing level around 700 metres. Today was mainly dry with a fresh Northerly wind.
Observed Snow Stability and Avalanche Hazard
Below 600 metres the snowpack is moist and generally stable. Above this altitude during the last 24 hours the snowpack went through a melt freeze cycle leaving the snowpack with a surface crust above 800 metres. New snow amounts are generally insignificant. On all aspects and altitudes snowpack stability is generally good. Some cornices are fragile.The avalanche hazard is Moderate.
Mountain Conditions
| Snow Distribution | Snow above 300 metres with main cover above 600 metres. |
| Icing | Freezing level around 800 metres. |
| Comment | A ridge of high pressure will give way to a showery North-Westerly airflow. Some dry weather and some precipitation the amounts are uncertain. |
