I might be remembering wrong, but with those recent Winter storms (last 10 years) in TX, I'm thinking there was even problems with natgas feeds into utility plants. Sad, as there were direct fatalities due to the bean-counters making the decisions, and not qualified/experienced engineers.
If you are not ready for it, even a minor Winter storm is a huge problem. A buddy of mine was in Windsor, ON (Eastern Kanada's banana-belt) during a Winter storm - he said the city only had one truck (a one-ton p/u) clearing snow on city streets !
So I do get it - for areas that rarely see snow, the best thing most people can do, is Stay Home and make use of all the emerg supplies you have stocked
