How this works: NASA/NOAA VIIRS satellites sweep overhead 4–6 times a day (roughly every 4–12 hours, day and night) and detect heat in ~375 m pixels. We compare where the older detections sit vs the newest ones — if the hot area's center has shifted, that's the direction the fire is moving. Hotspots on the map fade with age — brightest = newest. Estimates only; confirm with official sources.
