It is my practice to fill tanks of our two vehicles upon the event of a coming storm and possible power outage. In addition, I store 10 gallons of gasoline for my gasoline generator to power refrigerator/freezer and fans. Finally, I have two propane tanks for gas grill and griddle for cooking. I keep on hand 2 lithium battery fans which will operate approximately 8 hours each without recharge. These options should allow me to remain or evacuate. A power outrage of one week is not a problem. After one week, community back up options and plans are usually in effect.
