Hello from the hurricane belt, where prolonged power outages after a storm are guaranteed.
It's no fun losing a freezer full of stuff. If they are going to make a habit of this, next year start drawing down your freezer stock before the Santa Ana winds arrive. If they warn you that you might lose power for several days, turn your refrigerator and freezer settings to max cold, and put gallon jugs of water in the freezer. Then fill nooks and crannies with the 17 oz and 2L bottles. Take the stuff you care about and move it to the bottom of the freezer, especially if you have a French door model. It will thaw from the top down and the stuff at the bottom may still be frozen even after a few days without power. If you really want to prep, pull the ground beef out of the freezer. Thaw it, cook it, and refreeze it in freezer bags. Now it doesn't have to be kept frozen, and will be much faster to prepare when you're cooking on a limited supply of propane or charcoal.
And when the power does go out, throw what you need, including some of the cooked ground beef, into a cooler with some ice. Then throw a bedspread or blanket over the refrigerator and leave the door closed. It will help to block any air seeps around the seals and keep it cold or frozen longer.
Or you could have a giant neighborhood barbecue where everybody grills stuff as it thaws.
The whole country is wishing you guys the best.
