In reply to Luk e:
Went up to Moel Eilio yesterday (Wed). Nee good. 500m of "blue run" near the top. Really scoured and icy underneath. It was a good venue 2 years ago. The wind scoured a lot of slopes and leaving drifts down at valleys and gullies. Llanberis side of Y Garn looking across from Moel Eilio looked good yesterday. I'd like to check it out in the next few days. Carneddau look quite white from a distance but it can be deceiving.
I tried in January. Again, scoured by easterly wind. It looked good from upwind angle, ie, from Bethesda but not good from the top of Carnedd Gwenlliam. Very thin layer of powder.
It may be a bit different this time round. But my best bet is actually Berwyn near Corwen/Llangollen. I saw on the news this week with lots of drift at people's houses, shops. There's a thread in UKC saying Berwyn is really deep on one side and scoured on the other ( I suppose east side). I'm going to check that out in the next few days.
I haven't been on many mountains this week. Avalanche probably depends on which aspect you're going down. It's very variable I've heard so far. Like on Moel Eilio, there was hardly any snow; just frozen ice crust.
Let us know how you get on. I'm going to check out some icefalls in Ogwen tomorrow.
