Regarding snow in the south...
Let's just agree there are a lot of idiot drivers & look at a couple of legit reasons a freak heavy snow can reek havoc on a place like Birmingham, AL.
1. It's not feasible ($$) to keep the kind of equipment needed to clear snow. It won't be there long anyway. (Same about snow tires.)
2. Snow on roads melts during the day & refreezes overnight creating black ice, often hidden with a wind-blown layer of snow. You can slide into next week when you hit that.
3. Few power lines are underground. There are lots of trees, especially pines & trees with leaves because snow comes really late after trees leaf out in the spring. Snow plus these trees equal falling branches taking down lots of power lines & poles blocking roads. But then most of the snow melts before power lines are back up... unless YOUR power is out. Then the snow keeps you in the keeps you cold, dark, & stuck walking the neighborhood looking for coffee for 5 to 10 days.
Big snows in the south are remembered for 2 generations. We still talk about the blizzard of '93 & snowpocolipse from about 2016.
Don't forget get our tornadoes. Right now I'm in Tennessee cooking for chainsaw teams from Alabama helping people recover from Saturday night.
Oh well, my ADD is showing.
Stay safe everyone.
