Just before I get down to putting the lunch on, I glance at Twitter. @davebriggs says it’s just started snowing. A few seconds later, @stephenfry also reports a few flakes. @paul_clarke isn't cool or dedicated enough to know Mr Fry’s precise whereabouts, but I’ve got a vague idea of Norfolk or north London, and I have a reasonable idea where Dave is.
This gets me thinking about a wave of “it’s starting to snow” tweets that I know are going to be appearing. What might that look like on a map? As a historical picture of advancing snow fronts, or even a live, dynamic view of where the flakes will land next. Powered by the people actually experiencing it. On a scale and level of detail unachievable by any formal organisation (that I know of).
So I thought about a hashtag: #uksnowstarts or something like that. Another glance at the mobile, and I see #uksnow. Ah, beaten to it – oh well – so what’s this about then? Turns out #uksnow is starting to bubble with reports from weather-obsessed Brits about whether they have (or indeed have not) seen floaty white stuff in the air. >
