DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0215Z September 29, 2017
SMOKE: Western North America... A combination of wildfires throughout California, Oregon, north-central Washington, southwestern Idaho, and southern British Columbia and agricultural burns throughout the Columbia Basin in northern Oregon, eastern Washington, and northern Idaho were seen contributing smoke plumes of varying density. The most expansive smoke plume is associated with fires across northwestern California and southwestern Oregon. This plume extends from the wildfires in the Klamath Mountains northward into Puget Sound. Some smaller yet notable smoke plumes exist in southeastern Oregon north-central Oregon, north-central Washington, and southern British Columbia. Much of this smoke was moving off to the north to north-northeast. Mid-Mississippi River Valley... Numerous agricultural fires across eastern Arkansas, southeastern Missouri, northeastern Louisiana, and extreme western portions of Tennessee and Mississippi were observed contributing to a thin density smoke plume across the mid-Mississippi River valley. Although many individual smoke plumes are present, some of the smoke from these fires were merging into a larger region of smoke. The smoke across this area is moving off to the south-southwest. Southern Prairie Provinces... Many agricultural burns across southern Saskatchewan and southern Manitoba were seen contributing individual thin density smoke plumes over that region. Although these smoke plumes were not merging, the number of fires and smoke plumes warrants the mention of smoke across the area. These smoke plumes were observed drifting off to the southeast. -Hosley THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT AREAS OF SMOKE ASSOCIATED WITH ACTIVE FIRES AND SMOKE WHICH HAS BECOME DETACHED FROM THE FIRES AND DRIFTED SOME DISTANCE AWAY FROM THE SOURCE FIRE. TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. AREAS OF BLOWING DUST ARE ALSO DESCRIBED. USERS ARE ENCOURAGED TO VIEW A GRAPHIC DEPICTION OF THESE AND OTHER PLUMES WHICH ARE LESS EXTENSIVE AND STILL ATTACHED TO THE SOURCE FIRE IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE: JPEG: http://www.ospo.noaa.gov/Products/land/hms.html GIS: http://www.firedetect.noaa.gov/viewer.htm KML: http://www.ssd.noaa.gov/PS/FIRE/kml.html ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO SSDFireTeam@noaa.gov
