Gatwick is reading something like 15-20mph NE wind and Heathrow a little lower at 10-15mph NE wind, but both are increasing, and it felt worse than that, which may have just been the gusts, which are currently anything up to twice those figures.
It should be easy on the way home.
I think (famous last words) that snow should now be a thing of the past for London. We haven't had much snow anyway (and none for weeks), and it's unlikely that we'll have much this late in the season, it'll be too mild for it now. I think I can safely but the snow tyres away, unused, until next winter.
