weather-NwsAdvisoryAlarmExt

Each NwsWeatherProvider has a child Advisories Alarm Ext extension. This provides for alarms initiated by NWS-issued watches, warnings, and advisories of hazardous weather conditions, for the locale of this provider. By default, this extension is enabled.

NOTE: The WeatherService architecture for NWS advisories changed—this extension has minimal impact (single property, Enabled, and no other slots).

A child Alarm Properties container holds typical Alarm Source Info properties used to specify which alarm class is used, plus other standard alarm parameters. See the following for more details:

NOTE: Under the WeatherReport for this locale, the CurrentConditions component reflects a related alarm in its Status property, with its State property reflecting an enumerated value for the hazardous condition. The Weather Summary property reflects a subject description received from the NWS.

Property sheet access of NwsAdvisoryAlarmExt shows its configuration properties and the child Alarm Source Info container.
