LOL ((Wish)). Actually here in the cold parts, we all make last minute runs as well. You should see the grocery stores the minute the weather service says a snowstorm is a'comin. Good grief, people run to the stores and stock up like they may never see the outdoors again. But then when a blizzard is a'comin, you just never know! That's when I'm right there at the store as well making sure I have the essentials.
Midwest yesterday and today has had extremely high winds and storms. Around Chicago, Indiana, Michigan, and Ohio I believe, there were also numerous tornadoes. They said the winds were so furious it was like a category 3 hurricane in the midwest.
For us 'old folks'

maybe it's a hangover from when we were growing up fearing the atom bomb and everyone kept supplies stocked just in case. I'm not sure what 'just in case' as the atom bomb would have pretty much rendered the need for supplies useless, LOL!
I can't believe back then we would have regular tests at school in case of the bomb. They taught us to crawl under our desks and put our hands over our heads.

We also had the lovely
Conelrad emergency broadcast system.
