DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z September 21, 2020
SMOKE: CONUS, Central and Eastern Canada, and Northeastern Mexico… Wildfire activity across the western CONUS (mainly California and Oregon) was observed continuing to produce thick smoke this morning. The smoke plume from this fire activity is stretching from the source activity northeast and then east across Nevada, the southeastern half of Oregon, southeastern Washington State, southern Idaho, northern Utah, and along the Wyoming and Colorado border out across the Central Plains. From here, the moderate density smoke is being drawn northeastward and northward into a large cyclone centered over eastern Manitoba and northwestern Ontario. At the same time, some of the smoke is being drawn southwestward into a small ridge over the Four Corners region, where the smoke is thinning and dissipating. As a result of both features, a large area of moderate to thick smoke blankets a region from northern Texas into James Bay and Hudson Bay in central Canada. Smoke is moving further along across Quebec, Newfoundland, and New England and sagging southeastward and southward. Some of the smoke is also being drawn around the western side of Hurricane Teddy, located southeast of Bermuda. Light remnant smoke was also observed over the southeastern CONUS and the Intermountain West. Central and Eastern Atlantic Ocean… Detached light to moderate remnant smoke was also observed over the mid-latitudes of the central and eastern Atlantic. This area of smoke was being transported to different ways...one northeast into the UK and the other clockwise around an upper feature near the Azores. A few other entities, such as Hurricane Teddy and the remnants of Paulette, are also slightly affecting how the remnant smoke is moving through the upper feature. Mid-Mississippi Valley… Light smoke plumes from seasonal burning activity was observed early this afternoon across northeastern Arkansas and the bootheel of Missouri. The smoke was moving off mainly toward the west-northwest. 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/data/land/fire/currenthms.jpg GIS: ftp://satpsanone.nesdis.noaa.gov/FIRE/HMS/GIS/ KML: http://www.ospo.noaa.gov/data/land/fire/fire.kml (fire) http://www.ospo.noaa.gov/data/land/fire/smoke.kml (smoke) ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO: SSDFireTeam@noaa.gov
