You really need to prepare on the 1st of June.
We were up north all summer....just got back.
I know what you are saying though and it’s wise advice.
Where I came from the folks always got prepared for blizzards. Pantrys and freezers were well stocked and if a winter storm was forecast my mom filled up water containers and also filled the bathtub with water for washing as we could be without water and access to anybody else for several days if a whopper blew in and the roads were blocked.
