Gather all of your legal documents (deed to house, loan paperwork, birth certificates, pictures, social security cards, insurance docs, car titles, and any other documents and valuables), blankets, computers, 5 to 7 days worth of clothes, some food, water, drinks, snacks and other digital devices. Insure they are all secured in the vehicle you are going to use to vacate the area.
Also insure you have video and pictures of the now to include the inside and outside of your home, vehicles and land along with what the neighbors homes looked before you vacate the area.
Once you are sure you have everything, fill up on gas if possible and vacate the area and check the safety status of the area many miles away from the fire. To be safe go to a different county or city far away from the flames.
