Observed Avalanche Hazard - Sat 13/03/2010
Observed Weather Influences
There were some afternoon rain showers up to 1000 metres with strong North-West winds for most of the day.
Observed Snow Stability and Avalanche Hazard
There is a moist snow surface up to 1000m. At 950 metres on a Westerly aspect the snowpack throughout is in the -2 degree range 10 centimetres below the surface and is mostly dry and well bonded. The surface instability is isolated to the steepest aspects from 800-1000 metres. The avalanche hazard is Moderate.
Mountain Conditions
| Snow Distribution | Moist surface, skiable in most places. |
| Icing | Should become more exposed in the next couple of days. |
| Comment | Deeper and mid-pack is still good stability, although some of the lingering weaknesses persist. |
