Soldato
I used to look after my Mum, with advanced dementia and complex care needs, with no nearby relatives, and I don't drive. I dreaded even "trivial" power cuts or problems with water supply/drainage, let alone anything on this scale. It's easy to imagine options when I'm, as now, on my own again... I could easily walk ten miles inland if necessary. But the logistics of moving vulnerable folk around is daunting at best.the flip side to that is maybe some people cant evacuate, disabled, those without cars.
