I'm not sure that Tom knew about the riders. Perhaps he could feel that there was an evil near. As for the washing day, I think that it was just sort of a coincidence. I kindof pictured Goldberry washing clothes or something. Tom knew about the danger of the wights, and he warned the hobbits about them. Tom had many things to do, he did not really want to go with the hobbits, but he also liked the hobbits and did not want them to come to any harm. While they were within his boarders he would help them but not beyond that. Tom knew a lot of things, but he did not really care about other peoples probeblems very much. It is not that he was mean but he simply forgot or had other things to do that seemed more importent. Anyway, that is my opinion.
