Ben Marsh has updated his #UKSnow map just in time to capture a flurry of snow in the UK today. If you live in the UK you can add to this Google Map simply by tweeting the first half of your postcode and a score out of 10 for the snow in your location. The map updates to show the results every minute.
The Guardian has also reported on #UKSnow today. This has had the unfortunate effect of putting a lot of pressure on the #UKSnow servers - so be warned you might have problems viewing the page today.
