DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z August 29, 2020
SMOKE: CONUS (aside from the SE)/south-central Canada/northern Mexico/North Atlantic... Wildfire activity throughout the western US (mainly California and Oregon) and southeastern British Columbia continues to produce thick smoke, maintaining a continental wide area of varying density smoke. The area of smoke has its origins in mainly northern California and the Central Valley, with smoke moving off initially toward the west. Then, the smoke makes an abrupt turn off toward the east-northeast and continues over the Intermountain West into the Northern Plains and the Prairie Provinces. The layer then plunges south-southeast across the Central Plains and then toward the east across the Mid-Mississippi and Ohio Valleys, where the some has concentrated some. From here, the layer moves east-northeast across the northern Mid-Atlantic, southern New England, and out into the north Atlantic, where some of the smoke layer was starting to be ingested by a deep trough over the Davis Strait while the rest was concentrating within a high off to the south of the Maritime Provinces. Four Corners... Fire activity across Arizona is also the likely source of a region of moderate smoke over Colorado and New Mexico. Some of the fire activity was also producing light to moderate smoke this morning. SAHARAN DUST: Atlantic... Saharan Dust that has been moving west across the tropical and subtropical Atlantic has had portions of the layer move across much of the Caribbean and even towards the Yucatan Peninsula. The thickest Saharan Dust was still over the eastern and central tropical Atlantic and the eastern subtropical Atlantic. 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
