Where is tornadoes on Pokemon White?

Answer 1

tornadas is,well,heres what to do,do you know those green buildings that you would usually walk thru ,well go in one and you will need to watch the tv in it and it will say the date and then it will say there is a very unusual thunderstorm on some route and u go to that route and then it will start to rain and lightning will strike and when you run into the grass he will apear
First walk into the gate leading to Route 10 and a desk lady will tell you that there are storms appearing on Route 7. Once you go to Route 7 there will be a storm. Walk towards the only house on the route nest to Twist Mountain. The old woman will drag you out of the storm and give you some soup. While your eating she will tell you about the story of Thundorus (White) or Tornadus (Black). One you leave, you will encounter the Pokemon she was talking about, then it will fly away. After this, you will find him in the mornings on Route 5, or in the evenings on Route 9. you will know if he's there if it is raining in that area. If it isn't, walk out and walk back in and keep repeating this if it still isn't raining. Now he will Flee after one turn, but all HP done to it will be kept. So keep repeating the process until you catch it.
