I've been asked by family to do a checklist of things that they should be doing in and around preparing to be snowed in for an hour/day/week/month/till Christmas '18.

I also have two family members in the UK, one in London and one in deepest Wales, who are asking how they should be preparing. The Welsh one is probably better prepared than she thinks because it's a fairly regular occurrence for her. I remember the helpful lists in 2010 but damned if I can find any.provisions/actions lists here.
Also, I'm a scaredy cat driving on a bit of frost so any ice/snow is going to a challenge. I've ordered snow socks but any tips on snow driving - there's a short 30 degree hill out of one side of where I live down to a busy enough fast road and longer steeper hill the other way with a couple of nice turns into other estate roads on the way down. I usually hold my breathe and close my eyes on the way down which doesn't fill the neighbours with confidence.
Also tips for pets - dogs in particular - winter boots?
