Fast-moving fires ignited this week in parts of Ventura, Oxnard, Santa Barbara and Los Angeles, California. Heavy brush and strong dry Santa Ana Winds have fueled the active blazes, with expectant wind speeds reaching 80 mph. The largest Thomas Fire, Creek Fire and Rye Fire have so far burned a combined total of over 83,000 acres in two days (12/5/2017 - 12/6/2017). This image was created by combining three of the NOAA/NASA Suomi NPP satellite's high resolution thermal and visible channels from the VIIRS sensor (SVI 4,2,1). These different channels allow us to distinguish areas of land that are hotter in temperature (red) due to an active fire or a burn scar.
