Hmmm. If the option of a friend's or relative's house is ruled out then, I think, it would be time to shelter in place individually. Once the smoke clears you can use your out-of-town contact to coordinate a meeting spot and time (i.e. 'The fire hydrant at the corner of 5th and Main at 1630 hours"). I've used this system under mundane circumstances and its worked pretty well. The out-of-town party doesn't even have to know the geography of your area as long as you give them a precise description.
