NASA FIRMS detected two separate wildfires near California, with one identified on 4 June 2026 about 98 km northwest of the state and another about 41.4 km south along the coast. The northern fire showed higher energy release, while the southern fire appeared more localized. Last update: June 6, 2026.
The detections matter because satellite-confirmed hotspots can indicate active flames and spreading risk for nearby areas. Changes in fire radiative power (FRP) and hotspot patterns can signal intensification or containment, guiding public safety actions and resource allocation by emergency services.
Latest satellite detections and locations
The fire northwest of California was first identified on 4 June 2026 and consisted of six hotspots roughly 98 km from the state boundary in a northwesterly direction. In a separate detection, a second cluster was mapped approximately 41.4 km south of California near the coastalso showing six hotspots. While the exact terrain and jurisdiction are not specified, the spatial separation suggests two distinct incidents. Monitoring continues to refine position, extent, and movement as new satellite passes provide updated thermal signatures and confidence scores.
Intensity, hotspots and potential impacts
The northern wildfire recorded an aggregate FRP of 363.6 MW, indicating significant intensity consistent with stronger combustion and possible rapid growth. The southern fire showed a total FRP of 18.5 MW, pointing to a localized burn with lower energy output. FRP is a satellite-derived proxy for heat release and can help estimate fuel consumption and plume strength. Both incidents remain under observation, and intensity, size, and direction can change with wind, fuel, and humidity. Smoke may affect downwind communities depending on atmospheric conditions and topography.
Public guidance and ongoing monitoring
Residents in potentially affected areas should follow instructions from local authorities and emergency services. In an emergency, dial 911. To reduce smoke exposure, keep windows closed and avoid the area if safe to do so. Be prepared to evacuate if ordered and do not approach open flames. Agencies will continue to use NASA FIRMS and ground reports to assess risk and coordinate response. Updates will be issued as new data clarifies location, spread, and containment status.
