I'm afraid my approach is to not go overboard on the "Alert" phase. I sometimes use predicted events as a deadline to get my kit in order - the Millenium Bug was a big one for me - but I don't really do anything that needs undoing if the disaster doesn't happen. I mostly just do stuff that I enjoy. Preparedness isn't a chore for me, nor is it something I lie awake at night having anxiety attacks over.

Also, it's my experience that minor disasters do happen. For example, I got a bread-maker machine and started to stockpile flour for Dec 31st 1999. A few years later we had a fuel strike, supermarkets couldn't get restocking deliveries and their bread ran out after less than a week. So then it was useful to have my own stuff. Similarly I have gas central heating, and also an open coal fire. I came back from holiday one year to find the central heating broken. My stockpiles of coal meant I could keep the house warm anyway.
