Plot Description:

This chart shows the weekly frequency of having at least one watch/warning/advisory (WWA) issued by the Weather Forecast Office (top plot) and the overall number of WWA issued for that week of the year (bottom plot). For example, if 10 Tornado Warnings were issued during the 30th week of 2014, this would count as 1 year in the top plot and 10 events in the bottom plot. This plot hopefully answers the question of which week of the year is most common to get a certain WWA type and which week has seen the most WWAs issued. The plot only considers issuance date. When plotting for a state, an event is defined on a per forecast office basis.

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!
