I dont know if any of you guys have come across this site before but I find it very useful

The radar is great as its updated regulary and very easy to understand, for instance I can see that although its raining here now it will blow over in about an hour so i wll be able to go out again.
as soon as it starts to rain I check to see if its worth sitting it out in the van.
It has saved me hundreds of pounds turnover in the last 3 months just by making sure I dont make a bad call and tell the lads to "call it a day"
ps. click on the radar picture to enlarge, then zoom in and out
