It doesn’t matter if it’s a major ice storm, hurricane, or emp, or grid attack. Fill your bathtub, and your empty milk gallons. And if it is cold season with subfreeze llkely, drain your water system. Imagine if everyone is in a panic and all the pipes freeze the kind of recovery that would be needed. I remember when there was one storm crisis how desperate the people in that part of Florida were for water.
LOL! Yup. Being without power for a long stretch in July and August is NOT fun in Fla. Good thing we didn’t need to worry about charging our EV.
Another point. Our electrical infrastructure is a lot more robust than people think it is. A good hurricane or tornado or even a large thunderstorm packs a lot more energy than a nuclear weapon does. Mother nature challenges the grid everywhere every day.
