DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0234Z July 18, 2021
SMOKE: Canada/U.S./North Atlantic/Pacific off the coast of California... The extremely large area of varying density smoke remained this evening and attributed to ongoing extreamly significant wildfires occurring in central and southwestern Canada as well as a few wildfires in the northwestern and western U.S. Light to thick density smoke was seen over roughly the northern half of the U.S. with relatively smoke free areas seen over the southwestern U.S., and the south central and southeastern U.S. The thickest smoke was noted extending from wildfires in northern and northeastern California to the northeast over portions of Oregon, Idaho, and Montana where it joined with a thick mass of smoke which stretched from wildfires in southern British Columbia. Thick smoke then blanketed the far northern U.S. from California to Minnesota and much of the southern portion of Canada. The thicker smoke also appeared over east central and northeastern Canada to the east and northeast of Hudson Bay. Farther to the east, a batch of varying density smoke linked primarily to the Canadian wildfires was seen over the Atlantic well south of Greenland and Iceland. Alaska/Northwestern Canada… Wildfire activity mainly in central and east central Alaska and far northwestern Canada was responsible for an area of light to thick density smoke which covered virtually of Alaska with the exception of far western Alaska and the Aleutian Islands. The smoke also spread to the south over part of the Gulf of Alaska and to the east over the Yukon, Northwest Territories, and Nunavut of northwestern and far northern Canada. Thicker smoke was noted over central and southern Alaska and extending into the Gulf of Alaska as well as to the south and southwest of a wildfire in the central part of the Yukon. DUST: Southern and Eastern Texas/Eastern Mexico/Gulf of Mexico/Caribbean Region... Saharan dust was still visible over the far western Gulf of Mexico, eastern Mexico, and extending up into southern and southeastern Texas. A much larger and thicker area of Saharan dust could be seen east of Puerto Rico and extending to western Africa. Eglin 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
