Hurricane Forecast Maps

In moving back to Philadelphia from Chicago, I have forsaken polar vortices for hurricanes and nor’easters. And this current weekend, it appears increasingly likely that the weather will be impacted by Hurricane Matthew, presently tearing its way through the Caribbean. So of course I am following projections and forecasts of just where this storm will be headed.

Thankfully Mashable has an article that attempts to explain just what the National Hurricane Center (NHC) means when it publishes its cone of uncertainty charts. Because, according to the article, it turns out most people do not entirely understand just what it means.

US Fed Forecasts

Organisations that forecast things are not often inclined to go back and review their forecasts against the actual results. So that makes today’s post from the Wall Street Journal fascinating. They reviewed the Federal Reserve’s forecasts for US GDP growth against the actual growth. And it turns out the Fed consistently overestimated US growth.

From a design standpoint, what makes this piece interesting is how they presented the range of forecasts. After all, it would otherwise become a plot of squiggly spaghetti lines. Instead, they used colour to group each projection set. A smart idea. Plus a nice literary allusion. I mean if you like Dickens.
