Last year Esri updated the wildfire live feed hosted in the Living Atlas for the United States. This service leverages the Integrated Reporting of Wildland-Fire Information (IRWIN) location database along with the polygon perimeters from the National Interagency Fire Center (NIFC). View the live feed here.
The ArcGIS Living Atlas and Disaster Response teams have recently updated the layer with additional incident age fields as well as improvements to the cartography. See 2021 Wildfire life feeds update for more information.
