I feel for you. Wildfires can be very unpredictable.
Been through it twice: Southern California in the early 90's (where I woked for Public Works in Orange County so I was up front a close) and Colorado in the early 2000's: just not something I'd want to get close to again.
Pack irreplaceable stuff now, while you have a clear head: you're less likely to forget something.
Good luck!
