The forecast thaw is here--slightly more serious than I had expected, but ultimately good for conditions. The West Face of Aonach Dubh is looking completely stripped, and the snowline has gone up by about a hundred metres to about 800. There would probably have been mixed routes in condition on the Upper Tier yesterday; no chance of that now!
Weather is blustery and very mild, with a probable freezing level somewhere near the summit of Bidean, so I have decided to give mountaineering a miss for today. Even without the thaw, the galeforce winds overnight will have increased avalanche risk yet again.
