In reply to jhw:
I'd say going over to Etchacan, Braeriach or anywhere beyond the Northern Corries will be more aggro that it's worth this weekend, between gale-force southeasterlies and wading through drifts. My advice (and what I'm figuring I'll aim to do) would be to stay in Sneachda and exercise extreme caution about crag approaches and exits.... and steer clear of gullies. Expect to top out into a maelstrom and give serious thought to safe descents. Going over the top of point 1141 can be a battle, but argubly better than taking on an avalanche-prone lee-slope.
Good luck, it's not the most helpful prognosis!
