Where conditions make driving too difficult or dangerous, buses may be cancelled at short notice. If they make it through, they may be badly delayed. Unfortunately none of us can accurately predict what the weather will do, so we can't tell you in advance which buses will be running tomorrow...
I will keep the Twitter feed updated where I can, but I'm not going to be here 24/7, so your best plan is to check on each operator's own Twitter feeds, or phone the bus company you want to travel with.
