I store extras of all electronics in Faraday cages because of the possibility of a nuclear EMP. That would come with zero warning. I store a computer, shortwave radio, regular am/fm radio, a set of family service radios, a digital camera and memory cards, and some extra hard drives with backups of important files.
At least with solar flares and solar EMP, I get an email that gives me a couple of days to unplug things, if a large X class flare launches. I don't care about the direction. I just unplug until it's safe. So far, in over 10 years of getting alerts, we haven't gotten a really large X class flare. There have been several that affected communications a bit, but nothing drastic.
