Probably nothing but last week wife and I had a surreal experience when we walked into our local Meijer megastore and the entire place was without power. Lights out, fridges and freezers out, attendant said it had been more than an hour like that. Just registers running on backup gen. Creepy trying to shop in pitch black and they weren't selling cold or frozen goods so we booked it over to a different store. It was really weird, blackouts here are uncommon, a whole meijer shutoff for hours even more so. Weather was mild too.
