I personally don’t think the risk is currently high enough to justify evacuation if you live in the US (I’m not sure where you’re writing from). I think looking at escalations/de-escalations of conflict between nuclear powers as signals of risk makes sense. You could look at estimates like this one (https://forum.effectivealtruism.org/posts/KRFXjCqqfGQAYirm5/samotsvety-nuclear-risk-forecasts-march-2022) or check relevant metaculus questions.
