I am from Phoenix and am planning to go up to Flagstaff this weekend which is somewhat near Sedona. I'm not sure how much Sedona is affected, but I do know that if you plan to travel at all on the I-17 freeway, they think it will be closed on and off all weekend long while they try to contain the fires. They said that you can expect up to 10 hour delays! Sorry I can't be of more help.
