Sweet potatoes can survive in the ground over the winter in warmer locations, but they do not tolerate cold weather, so it is mostly treated as an annual planting. Starting each growing season with a new slip (either purchased from a local garden center or nursery, or you can start your own) will likely give you a better result and hopefully a crop that will last well into the winter.
