DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0001Z September 12, 2021
SMOKE: Lower 48 of the U.S/Southern Canada/Atlantic off the East Coast of the U.S. and Canada/Mexico/Gulf of Mexico… Varying density smoke, primarily from the ongoing significant wildfire activity over the western U.S. with smaller contribution from a few wildfires in southern British Columbia and numerous daily smaller seasonal/agricultural type fires in the central and south central U.S., was visible this evening covering most of the lower 48 states of the U.S., portions of southern Canada, the northern half of Mexico, the northern Gulf of Mexico, portions of the Atlantic along and well off the east coast of Canada and the U.S. A substantial part of this huge area of smoke was moderate in density especially across virtually all of the central U.S., a portion of the Mid-Atlantic and southeastern U.S. regions, northern Mexico, south central Canada, and also along a line from northern California to central Montana. Cloud cover over eastern Washington, northern Montana, and over the border into southwestern Canada prevented detailed information on the extent and density of the smoke in these areas in satellite imagery. DUST: Caribbean: An area of thin density Saharan dust was seen spreading to the west over the southern part of Hispaniola, Jamaica, the central Caribbean Sea, and northern South America. Rodriguez 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
