There's a new free website showing real time rainfall across the UK -
www.raintoday.co.uk You can search by postcode or location, and zoom in
to street level.

I have just changed my plans for today, based on what it said!

Thank you for a very useful link Beatrice.

Indeed that is a good site.Thanks
If the hill opposite our house vanishes I know that I have 5 mins to rush
outside and do whatever I need to do. also if I can hear the trains two
fields away we know that the rain is coming over the river :-)
