There's a lot of collective wisdom on the site. I would pay careful attention to the air quality. I would keep some eye drops handy and a wash cloth, handkerchief, or bandana that you could wet and cover your nose and mouth. Check in with neighbors, friends, and family periodically as situation progresses. Let others know your plans. Have your car filled with gas and ready to go. Be prepared for a minimum of 2 evacuation routes. I would keep abreast of local news and probably set alarm clock to re-check every few hours during the night.
