It was a fairly calm day on the eastern periphery of the Creag Meagaidh area, with thin cloud making observations challenging. The good news is that it was around 4 degrees Celsius in the valley indicating freezing temperatures at summit elevations.
A change is expected overnight and tomorrow due to the passage of Storm Otto. The first named storm of the season has resulted in a yellow warning for rain fall and high winds for much of Scotland. Correspondingly, a period of instability is expected overnight due to heavy rain, with between 40-50mm forecast. The snowpack although limited in extent, will become saturated and wet loose avalanche occurrences are likely in steep locations along with cornice collapse.
After this avalanche cycle the freezing level will fall slowly consolidating the snow that is left. I say what is left, because we could be looking at significant snow loss even at the highest elevations…
