Five years of American drought, visualized

At Adventures in Mapping, John Nelson developed a sobering series of maps that visualize the intensity of the drought gripping much of the US:

This is a map showing over five years of drought data (285 weeks, combined into a single view) in the United States. The dots are proportionally sized by the amount of time over the past five years spent in drought (the largest dots representing 80% – 100% of the time), and the color is a weighted value of the overall intensity of those droughts (deep purple indicates frequent “exceptional” drought, the most severe category).

Lots of other beautiful but disturbing maps in the post.
