Plot Description:

Gantt chart of watch, warning, and advisories (WaWa) issued by an NWS Forecast Office for a start date and number of days of your choice.

The width of the bar is the duration of the event and is a bit difficult to explain for some WaWa types. The color shaded area represents the maximum period at least one county/zone was included in the event. The hallow area represents the period between when the NWS created the event to when it first hit its issuance time. This is a quirk of how VTEC works with things like winter storm watches going "into effect" at some time in the future. When there is no hallow area, these are events that went into effect immediately at issuance. For example, Severe Thunderstorm Warnings are all this way.


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!
