Good idea. I don't think there is any restriction or check made on wind 
direction field, you can put anything you want.

Yes but we have to know if:
1- METRo produce a good road forecast doing this way (I hope you'll be 
able to answer this);
2- If it could be useful. Do you know if there is a lot of RWIS station 
that possess and use this sensor?
