Great explanation of the Incident Detector behavior, we had a similar problem and ended up replacing our Incident Detector with a Filter and found that checking when GEOMETRY points are INSIDE a Weather polygon GeoFence produced duplicate alerts with every poll refresh of the input points. We switched INSIDE in favor of ENTER GeoFence and added a TRACK_ID tag to one of our key fields in the Input GeoEvent Definition. This helped prevent the duplicate alerts.
See below for a Visual representation:

Hi,
I have created an idea on the ArcGIS Ideas site to get incidents to return the name of the geofence they are related to here: https://community.esri.com/ideas/12395
I think this would be a good enhancement.
Cheers,
Marc
