http://www.isleofwightweather.co.uk/live_storm_data.htm is great if you fancy yourself as a bit of a storm chaser! but back to the competition.
To enter this one, simply buy a Walkers Crisps Multipack (on offer in Sainsburys at the moment! so that's double win) go to http://www.walkers.co.uk/ sign yourself up and then you get to choose a grid reference somewhere in the UK, X days in the future and if it rains on that exact spot, then Walkers gift you £10.00. What could be simpler? after all this is the UK, so it should rain, lets face it most of the time! or do Walkers know something we don't for this Autumn? I'll let you know how I get on!
