DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1600Z August 23, 2021
SMOKE: U.S./Canada/Pacific... Large wildfires in the western U.S. and southwestern Canada continued to burn today and were responsible for a large area of smoke seen across portions of the U.S. and Canada as well as off the U.S. West Coast. Dense smoke primarily from the wildfires in the western U.S. stretched eastward across sections from southern to northern California into central/northern Nevada into southeast Oregon, southern Idaho, extreme northwest Utah and Wyoming, into all of southern Montana, northeast Wyoming and into western and central South Dakota. The most dense areas of smoke extended across northern California and into southern Oregon, northern Nevada and southwest Idaho. Lighter density smoke extended off the California coast and north into central and some parts of northern Oregon, across central and northern sections of Idaho and Montana, into south central Canada, across all of North Dakota and South Dakota and northern Nebraska, northern Utah and most of Wyoming and as far east as the Mid-Atlantic and moving into the Northeast and reaching southern central sections of Quebec and western/central Ontario covering in the path the Great Lakes region. Smoke may extend farther east, but difficult to see the full extent and some is very light. Northern Canada... Thin density smoke was seen spreading to the east and across northern parts of Canada from northern British Columbia and the Northwest Territories to northern/central Ontario. The smoke may reach farther east. Smoke was most likely sourced from fires burning in Siberia a few days ago. Kibler 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
