Rumours of my iciculation are greatly exaggerated. I just went to bed and slept solidly for 11 hours, without so much as getting up for the loo. I don't think I've done that since that night in Llanberis.
The power stayed on, which meant the computer did whatever was necessary heating-wise to keep the temperature in the bedroom above 16C (the temperature previously determined to be warm enough not to exacerbate any low-level asthmatic nastiness I may be suffering from). I also had two duvets, an electric blanket and - as barakta's away in That London - the use of both hot water bottles (one for each foot! Luxury!).
We also have a memory foam mattress, which doesn't appear to have exploded or anything through hot water bottle use yet...
The snow situation is much the same as it was last night, only presumably icier. No sign of polar zombies, but I'm a reasonably safe distance from Broad Street.
