Real-time wildfire tracking
across America.

Active fire perimeters and incident points come from the national interagency feed (NIFC / WFIGS) — the same source federal and state fire agencies use. Smoke plumes come from NOAA's Hazard Mapping System, red flag warnings from the National Weather Service, and drought status from the U.S. Drought Monitor.

An NWS warning that critical fire-weather conditions are occurring or imminent — typically strong winds, low relative humidity, and dry fuels together. It means any ignition can spread rapidly. Toggle the red flag layer on the map above to see every active warning polygon.

Fire perimeters and incident data refresh throughout the day as agencies update WFIGS — mapped acreage can lag rapid growth by several hours. NWS warning polygons update as they're issued. Smoke and drought layers update daily.

The table shows the last mapped perimeter, which is surveyed by aircraft or satellite and updated on a lag. During fast-moving events, incident commanders' verbal estimates in press briefings will run ahead of the mapped polygon.

NOAA classifies satellite-observed smoke as light, medium, or heavy — drawn here from light gray to black. Heavy plumes generally track with unhealthy surface air quality downwind, but smoke aloft doesn't always reach the ground.

No. Snoflo is informational. For evacuation and life-safety decisions always follow local emergency management, CAL FIRE / your state forestry agency, the NWS, and law enforcement.
