Plot Description:

This application presents a calendar of daily counts of the number of watch, warning, advisories issued by day. This accounting is based on the initial issuance date of a given VTEC phenomena and significance by event identifier. So a single Winter Storm Watch for 40 zones, would only count as 1 event for this chart. The concept of a calendar date needs some explanation. The calendar date is either US Central Time or the time zone of the local NWS Office or a 12 UTC to 12 UTC time period. For the 12 UTC case, the date represents the start of that 24 hour period.

You can also generate this plot considering "ALL" NWS Offices, when doing so the time zone used to compute the calendar dates is US Central.
