Current Snowpack Conditions

Current Snowpack Conditions
15-20cm new snow from light North-Easterly overnight above 2200m and drifted to 50cm in some areas This overlies generally on well-consolidated spring snowpack. Above 2500m on shady aspects, you can still find cold wintery snow with crusts and facets combo which formed fine spells two weeks ago. Below 2200m the isothermal snowpack exists and the cloudy weather has been preventing good freeze overnight. The snowline is lifting from low elevation quickly.

Mountain Weather

Mountain Weather
A few showers from North developing next few days. 20-30cm of new snow above 2100m forecasted till Monday 3rd.
