I’m in Texas but in far west TX with a different power grid that the central part of TX. We were also on the edge of the storm and so had warmer average temps than much of the state. El Paso is generally not prone to typical disasters but increasing extremes from climate change make everyone vulnerable. But the time to start thinking about disaster prep is when everything is fine, not on the eve of the disaster.
I’m thinking that if I were in Central TX and I knew this storm was coming I would stock up on non perishable food and potable water, gas up the car, make sure all batteries and portable electronics are charged up. Have the stuff to make hot drinks with just water. In hindsight it appears that filling the bathtubs and any other water containers available would be wise. Perhaps turning off the main water supply if possible. Dig a pit toilet in the yard before the ground freezes.
Have a supply of firewood every winter if you have a way to burn it.
Have a generous supply of drinking water at all times. I always have multiple gallons.
Always keep your gas tank full and some cash on hand.
Buy some solar chargers.
Don’t forget you need pet food and water for pets if you have them.
Buy a generator of some kind if you can afford it but keep in mind gas powered ones need gas. Remember no fossil fuel burning device can be running inside.
A propane camp stove or burner (like for seafood boils) or grill to at least heat water.
Have a water filtration system, even a camping style water filter on hand.
I’m sure that many of you are better preppers for disaster than I am. What can be added to the list that makes sense for a homeowner who needs to shelter in place?
