it really depends on the blizzard and how badly it affected the area it hits. yes, the blizzard rarely lasts for more than a day or two, but the effects of what it does can last longer. roads are snowed in/frozen over so help can't get in. powerlines are ripped/frozen down. pipes freeze and burst. those can take ages to get fixed, depending on the place hit and how much help is needed to fix it.

and when you have blizzards hitting places that aren't built to sustain it (most of canada is used to blizzards and has preparations in place. texas does not. neither does iran.) you get people who have no idea how to prepare or fix what's been damaged. texas isn't used to super cold weather, so when the southern united states gets blasted by blizzards, it can kill more people than it might in the north who are prepared. same as the north getting hit by heat domes and cities that aren't built with heat in mind having no ac or cooling measures in place winding up with death tolls.

you are incredibly ignorant and entitled in your experiences being the litmus of the world.
