GOES-16 (GOES-East) “Red” Visible (0.64 µm) and Shortwave Infrared (3.9 µm) images (above) showed the smoke plume and thermal anomaly or “hot spot” (dark black to red pixels) associated with the Trail Mountain Fire in Utah on 20 June 2018. Once the smoke was lofted to higher altitudes (in 2 distinct pulses) it quickly fanned out southeastward toward the Utah/Colorado border, transported by northwesterly winds around the periphery of a ridge of high pressure that was building into the Southwest US.
