Stockpiling?

So, I would like to be cautious and buy some extra groceries and non-perishable goods, but husband says I am way overreacting, he did the same thing during Harvey and we barley made it with the stuff we had in the house before the stores open, and we had been lucky we did not lost power, if we actually had lost power, it would have been a total different story. So, any of you already buying some extra stuff now? Or y’all think I am also overreacting. Thanks
