I have been seeing an unusual degree of denial about the snowstorm that reached Downingtown a few minutes ago. One coworker looking at the snow forecast map said, “We’re on the line between 6 to 12 inches and 12 to 24 inches, so we’ll get about 6 inches.” That is not only mathematically wrong, but isn’t the right way to plan for a potential disaster. The local forecast for this storm hasn’t changed much in the last five days, so the arrival of snow shouldn’t take anyone by surprise. Nor should it be too surprising that the blizzard warning already in effect for points east has been stretched west to cover Downingtown along with much of eastern Pennsylvania. There is a blizzard warning because, along with the heavy snow, there will be wind gusts creating occasional whiteout conditions.
In a way I guess I understand the skepticism. It is the middle of March, after all. When I got home late this afternoon, it looked like an early spring day, not like a setup for a blizzard three hours later. But part of the skepticism comes from the political conversation in which science, evidence, and caution are all treated dismissively. The budget proposal drastically cuts spending on infectious diseases, economic statistics, and weather forecasting alike, as if flu, unemployment, and snow were problems we could just wish away. Positive thinking has its place, but the snow deniers who turn a blind eye to a blizzard are putting themselves and others needlessly at risk.
In a severe winter storm two years ago a church near here saw a huge hole in its domed roof. The flat area at the top of the roof had too great a tendency to accumulate snow in a heavy snowstorm, and the dome was not strong enough to support the weight of that much snow. That church raised the money to rebuild its entire roof, and it is not a dome this time, but a structured roof with sufficient slope to shed the bulk of the snow that will be falling tonight and tomorrow. Having seen the damage that a disaster can bring, you take the risks more seriously. I hope today’s episode of weather denial is a passing whim, with some of the same people saying tomorrow, “What do you know? The forecasters said there would be snow, and we have snow!”
