The fire thermal anomaly first became evident in Shortwave Infrared and Near-Infrared imagery at 0421 UTC or 9:21 PM PDT on 23 October (0421 UTC image<\/strong><\/a> | 6-minute animation<\/strong><\/a>). A weather station close to the fire (Healdsburg Hills<\/strong><\/a>) recorded winds gusting to 76 mph<\/strong><\/a> less than 2 hours after the fire started; at that time, the Relative Humidity was only 11%. Above-normal temperatures were also present across that region of California, with Downtown Oakland setting a daily record high of 89\u00baF.<\/p>\n At times the fire’s hot thermal emissions were detected by 13 of the 16 spectral bands — including very subtle signatures in the “Red” Visible (0.64 \u00b5m<\/strong><\/a>), Near-Infrared “Vegetation” (0.86 \u00b5m<\/strong><\/a>) and “Cirrus” (1.38 \u00b5m),<\/strong><\/a> and Low-level Water Vapor (7.34 \u00b5m<\/strong><\/a>) bands (below)<\/strong><\/em>. The hottest Shortwave Infrared (3.9 \u00b5m<\/strong><\/a>) brightness temperature observed was 138.7\u00baC (411.9 K), which is the saturation temperature for those ABI detectors.<\/p>\n Since overlapping 1-minute GOES-17 Mesoscale Sectors provided 30-second Visible images,<\/em> the westward transport of dense smoke from the fire source could be followed in great temporal and spatial detail (below)<\/strong><\/em>. Note that a ship about 50 miles offshore reported smoke at 18 UTC<\/strong><\/a>. Just south of the dense plume, smoke was being reported at Santa Rosa — but the surface visibility remained at 10 miles<\/strong><\/a>.<\/p>\n GOES-17 “Red” Visible (0.64 \u00b5m)<\/em> images, with surface reports plotted in yellow [click to play animation | MP4<\/strong><\/a>]<\/p><\/div>A larger-scale view using the GOES-17 CIMSS Natural Color<\/strong><\/a> Red-Green-Blue (RGB) product (below)<\/strong> <\/em>indicated that smoke had been transported about 400 miles offshore by 20 UTC.<\/p>\n GOES-17 CIMSS Natural Color RGB images [click to play animation | MP4<\/strong><\/a>]<\/p><\/div>A toggle between Terra MODIS True Color and False Color RGB images from the MODIS Today<\/strong><\/a> site (below) <\/strong><\/em>provided a more detailed view of the smoke plume and the thermal anomaly (shades of pink to red)<\/em> associated with the large Kincade Fire (as well as the much smaller Muir Fire near the coast, north of San Francisco).<\/p>\n<\/a><\/p>\n<\/a><\/a>
