Plot Description:

This plot shows the weekly change in drought monitor intensity expressed in terms of category change over the area of the selected state. For example, an arrow of length one pointing up would indicate a one category improvement in drought over the area of the state. This plot uses a JSON data service provided by the Drought Monitor website.

In the case of plotting contiguous US values, the magnitude of the change values is multiplied by five as drought changes at that scale are slower than at the state scale when normalized by area.

Based on a sampling of recent timings for this application, plot generation time has averaged 3 seconds. Hold on for the plot is generating now!
