I lived in South and Central Texas for most of my life. We ALL knew to drip faucets when it went below freezing. We ALL knew to fill the bathtub and every other available container with water when a hurricane was coming and to have plywood around to board up windows. Or at least I thought we ALL knew these things.
Two years ago, I moved to Colorado. The first winter was record snowfall. My Texas winter clothes were a joke. Didn't take me long to figure that out, lol. The house I bought has a crawl space, never heard of that, and when the realtor said I didn't have to worry about dripping faucets, the outside faucets were frost free and the crawl space protected everything else, I thought, "yeah, right." I placed a remote thermometer in the crawl space and the temp down there has never gone below mid-40'sF. I covered the outside faucets until a plumber showed me how they work and had a little laugh at my covered ones. Never heard of frost free faucets. And the water line coming into my house is buried at 38"+ (don't ask me how I know) and all run through the crawl space and up on inside walls. Same with gas and electric lines. This house was built for this climate and I am thankful for that.
I still have close friends in Texas and the past week was a challenge but they are former full timers and long time campers and know how to be prepared for most anything. The one thing that is now on her list is a Birkey, altho she did have cases of bottled water stashed. Also on her list is a generator for the freezers full of meat. Luckily, she had rolling power and lost none of that. Her husband is deployed overseas. It was her and her two teens, and she invited a woman and her three young children who had no preps for anything. Water was just a trickle but they caught it in pots, etc., and boiled it during the short periods when power was on. Used fireplace for heat, (buddy heater as backup) blanketed off doorways, and they all slept in the living room. Two adults, five kids, two large dogs, four guinea pigs and they rigged up a "hobo hut" outside for the feral cats she feeds. Oh, and the roads were iced over so no going out for anything. They did fine. In fact, they went sledding, made snow people, and since no power for remote schooling, no school! A vacation time. These folks know how to make lemonade.
Btw, when I quit wheeled living, I kept the buddy heater, the birkey, and all the camping gear. Just in case.
