Dorsal Arete and Boomerang Arete..

The weather has been mixed over the last three days with rain to high levels, fresh snow and freezing conditions. I have been working for Plas Y Brenin for the last few days visiting the Ice Factor, and Coire nan Lochain.

There has been plenty of fresh snow, some of which has fallen under high winds resulting in significant accumulations of windslab and a correspondingly high avalanche risk. The harder mixed buttress routes are likely to be in good condition in many locations, assuming that you approach them.

With strong winds swinging around to the North West we could be looking at good "route building" conditions on Ben Nevis. Keep your eye on the SAIS reports....
