Snowpack stability is poor, especially in new snowdrift accumulations at typical locations - along ridges, in ravines, etc. Here, a small additional load can trigger a medium-sized avalanche.
The old snow cover has been transformed - frosted in the washes, cut on the washes. In some places, there was a hard crust on the surface. More than 100 litres of precipitation had fallen on such a surface since Friday night, most of it as snow above 1500 m. It is likely that more than 50 cm of snow fell. Where snow has fallen on hard, frozen ground, it has not bonded well with it. In the osoyas, the snow fell on a snowpack that was almost completely cut. It snowed with a strong SW-SE wind, especially near the ridges, which caused snowdrift accumulations. The snowpack is expected to thin out somewhat today.
Today will be cloudy and foggy at first, clearing in the afternoon. A light to moderate northerly breeze will blow. Temperature at 1500 m will be around 0 °C.
Tuesday morning will be sunny, with clouds starting in the morning. South-westerly winds will blow. Snow is likely on Wednesday. The avalanche danger will remain similar until Wednesday.
