First thing I would do is get the wife moving having her get important documents, photos, med's etc., Also the pets. While shes doing that I would be hooking up the trailer which is fully stocked and ready to go. Next thing would be to grab all the extra food and water. My truck and her SUV already have our BOB bags in them, my truck also has a tent, sleeping bags food & water and heat in case we have to ditch the trailer. I like to have all the bases covered. Truck also has extra gas in it, tools and fluids. Truck and SUV always have at least half a tank of gas never less, I also carry a hose and fuel pump in case I need to get more. Secure house and let other family members where we're going.Last but not least weapons and ammo.
