DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z July 15, 2021
SMOKE: Canada/Northern CONUS/Greenland/North Atlantic/Pacific off the coast of California/Baja... An enormous area of smoke of varying density covers much of the U.S. with the exception of a portion of the far northwestern U.S. generally west of the Cascades and the South Central and Southeastern U.S. Smoke also blankets much of Canada with the exception of far western Canada and a portion of Quebec and Hudson Bay though cloud cover in these areas hindered detection of smoke from satellite imagery. In addition, a moderately dense to thick area of leftover smoke was seen over the northwestern Atlantic to the south of Greenland and to the east of the Canadian Maritimes. Finally, thin density smoke also appeared to extend to the southwest and off the coast of southern California and Baja. Virtually all of this smoke was due to a very significant number of wildfires across central, south central, western and southwestern Canada and across the northwestern and western portions of the U.S. Within this huge mass of varying density smoke was a large patch of thick smoke affecting a sizable portion of the northwestern U.S., as well as southwestern, central, and south central Canada. Moderately dense smoke extended farther to the east and southeast of the area of thick smoke and was seen over the north central and central U.S. and from the Middle Mississippi Valley region to the east and northeast as far as a portion of the northeastern U.S. and the Mid-Atlantic region. Alaska… Wildfires were still detected in satellite imagery especially over central and east central Alaska with thin density smoke also visible over a good portion of Alaska, the northern part of the Gulf of Alaska, and the Yukon in northwestern Canada. DUST: Eastern Mexico/Northern Central America/Gulf of Mexico/Caribbean Region… A rather thin layer of Saharan dust was visible this morning spreading to the west over eastern and southeastern Mexico, the western and southern Gulf of Mexico, northern Central America, and a good portion of the Caribbean region including Puerto Rico and Hispaniola. More Saharan dust stretched from just east of the Caribbean region all the way to the west coast of Africa. JS 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
