Alerts workflow

First, a poweruser creates weather events by defining relevant meteorological criteria. The list of these weather events will be available to all users when they create areas of interest.

Next, users must create areas of interest, and select which weather events to monitor within each area. The selected weather events will trigger alerts when they occur within the area.

When creating an area of interest, the user can select the severity level of the alerts that are triggered within that area.

Weather alerts related to radar data have a hysteresis period of 20 minutes. If new events of the same type, and in the same area of interest, arrive, IRIS Focus keeps the alert active. Once there have been no new events for 20 minutes, the alert is cleared.
