Plot Description:

This application generates per WFO maps of VTEC event counts. The current three available metrics are:
  • Event Count: The number of distinct VTEC events. A distinct event is simply the usage of one VTEC event identifier.
  • Days with 1+ Events: This is the number of days within the period of interest that had at least one VTEC event. A day is defined within the US Central Time Zone. If one event crosses midnight, this would count as two days.
  • Percent of Time: This is the temporal coverage percentage within the period of interest. Rewording, what percentage of the time was at least one event active.

Note that various VTEC events have differenting start periods of record. Most products go back to October 2005.

Based on a sampling of recent timings for this application, plot generation time has averaged 7 seconds. Hold on for the plot is generating now!
