Plot Description:

This chart shows the time partitioned 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 events (bottom plot). This plot hopefully answers the question of which day/week/month 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.

Updated 21 Nov 2023: An experimental attempt is now included on the plot to estimate the climatological favored period for the given event type. This algorithm is experimental and attempts to make life choices on if it thinks the climatology is bimodal or not. Feedback welcome!

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!
