Plot Description:

This chart displays the number of products issued by a NWS Office or state by year for a given watch, warning, or advisory of your choice. These numbers are based on IEM archives and are not official! The counting is summing up distinct events. If one tornado watch covered 40 counties, this would only count as 1 for this plot.

Since the year 2005 and 2008 are common start years for VTEC tracking of various phenomena, when this app encounters those years as the starting point of the plot, they are droppped from the display.

Based on a sampling of recent timings for this application, plot generation time has averaged 2 seconds. Hold on for the plot is generating now!
