ATS Fire Line shows active United States wildfire operations drawn straight from the National Interagency Fire Center's WFIGS services: current incidents in the interagency system and daily fire perimeters, both refreshed every five minutes. Incident markers are sized by acres on a log-spaced ramp and colored by percent containment, prescribed burns are drawn apart from wildfires, and perimeters carry an ember fill. Filter by state or minimum acres, sort the largest-fires board, and open any incident for containment, personnel, cause and days burning. This is a data-visualization map: it reads public mirrors that lag operations and must never be used for evacuation or suppression decisions.
