Fires burned across California in late 2019. Fall is the state's most dangerous season for wildfires, propelled by dry and windy conditions. In recent years however, the fall fire season has been starting earlier and ending later.

A series of images from the MODIS sensor on NASA's Terra and Aqua satellites show the Kincade Fire in northern California. This fire started on October 23rd. By the end of the month it had burned 77,758 acres. A strong wind from the northeast is evident as smoke billows from the fire toward the Pacific Ocean.

Europe's Copernicus Sentinel-2 satellites captured more detailed images. The fire burned some areas already hit two years ago by the Tubbs Fire. Strong winds created small isolated fires seen as a pattern of hotspots in the images. Evacuation zones included the entire towns of Geyserville, Healdsburg, and Windsor, and the northern part of Santa Rosa.

As the Kincade Fire burned in the north, several fires hit the Los Angeles area. A Landsat 8 image from November 6th shows scars of the Saddle Ridge, Getty, Tick, Easy, and Maria Fires. The Maria Fire was the largest in this region. It burned nearly 10,000 acres in just 6 days.

Data from these three satellite systems complement each other to provide a complete picture of wildfires statewide.
