Along those lines, I know that some people 'plan' on using the water from their hot water heater tanks, or else their pressure tanks, if the power goes out for a while as emergency water. If that might be you, then do consider flushing it out while things are good (the power is on, there's no emergency as of yet, and you're not stuck at home already). Sediment at the bottom can build up. It's yucky, beside being bad for your hot water tank. Also get a short piece of hose so that the drain at the bottom of the tank is actually useful, since it's so close to the floor, as filling pots and buckets can be difficult without a little hose piece to attach to it.
I remember the last time we had a significant ash plume float over Anchorage and the Valley. The power plant in Cook Inlet had trouble with their generators and several of them were shut down so that if anything happened to the ones running, there was backup. I don't recall if we had power outages - does anyone else?
It's good to be prepared in case of an ashfall that lasts more than a day or two. It could be done with now, or it could do this for months. Adequate animal supplies such as food and water are important to have on hand. We have generators here to pump water from our well so that the more than 100 head of sheep and goats won't go thirsty. Buckets and barrels can be filled with water and you can even put a Saran Wrap type product over the top to keep them clean from dust and ash. When power companies shut down to save their tubines, you might not have electricity. And no heat. And of course, no water. Thinking ahead and being prepared can be a comforting feeling. Maybe today's a good day to go shopping - yay, and excuse to shop!! HAHA!
