Lo esencial

With warm and stable weather in the forecast the Alpine playground is likely to be pretty inviting over the next few days. Watch for increased avalanche activity/instability on solar aspects as the forecast strong temperature inversion kicks in.

Weather Forecast

A strong upper ridge aloft is creating a pattern of stable weather which is forecast to persist in to next week at least. A warm pacific airmass slowly nudging it's way North East will ride up over the present cold air, creating a strong temperature inversion with highs approaching 0 degrees in the Alpine by Thursday afternoon.

Snowpack Summary

5-10cm of light new snow has buried windslabs formed by the weekend's Mod-Strong SW winds. Below, old layers of settling storm and wind slab are interspersed with two thin layers of facets and possibly surface hoar which continue to slowly stabilize. This overlies the Dec 9th crust (down 50-90cm), still a concern as a developing weak interface.

Avalanche Summary

A few naturally triggered loose snow avalanches up to size 1.0 have been observed in the past couple of days.

Confidence

Intensity of incoming weather systems is uncertain
