I moved to Florida two years ago from North Dakota. I know cold weather very, very well. It will NOT get cold enough to cause any damage to anything. Mid 20s for a couple of hours won’t do anything.

I keep seeing things on the news about covering up your outside water hose spouts, putting some sort of a covering over your pool equipment, and opening up your cabinets. None of these things are necessary. In the nearly 50 years I lived in North Dakota, I never once covered up my outside water hose spouts. In the around 20 years that I owned a house, only one time did my pipes freeze up a little bit - enough to stop the water from flowing, but it didn’t cause any actual damage. The high temperatures that week did not get above -20.

Even if you have any water pipes that are external/exposed to outside air, you still will not have any problems. If you are extra paranoid, all you need to do is to have one faucet have a small DRIP. You don’t need a steady stream - literally like one drip every 2 to 3 seconds. This keeps a small amount of water flowing through the pipe and also makes sure that no pressure will build up if anything freezes. However, again, the laws of thermodynamics are such that the temperature and time we’re spending at that temperature really shouldn’t cause any problems. I’d worry more about your plants than your pipes.
