The European Drought Observatory maps drought the way meteorologists map extreme weather: it maps watches, warnings and alerts based on a lack of rainfall, a lack of soil moisture, and stress to vegetation following a lack of moisture, respectively. In addition to the online map viewer, there is a comparison tool and a way to generate your own maps from the data, among other tools. As of early August, the Observatory says, 47 percent of EU territory is facing warning conditions, 17 percent in alert conditions. It’s been a bad summer. [Maps Mania]
