I'm not sure about sending them, I guess now is as good of time as any since you can't wait too much longer. I would definatley say something on your website, because otherwise you are just ignoring the pink elephant in the room. Everybody is going to know and it just seems like the right thing to do to me to acknowledge it and say, hey this sucked but its over now and the travel alerts are lifted and hey the wedding isn't until November anyways!
