DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0001Z July 31, 2021
Canada/U.S... The expansive area of moderately dense to very dense smoke remained this late afternoon and evening. The smoke is attributed to significant wildfire activity in central, south central, and southwestern Canada, along with the northwestern and western US. Smoke continues to be observed covering an area extending from the Pacific Northwest into and across northern/central Canada, parts of the northern US and from the Mid-Atlantic into the southeastern US/Mississippi Valley and eastern sections of central/southern Plains. Areas of thick density smoke stretched across parts of central Yukon Territory and into central sections of British Columbia, central/southern Alberta, southern Saskatchewan, southern/central Manitoba and into the northern US from Montana into northern Minnesota. Light smoke was seen from Alaska across most of western/central Canada with cloud obscuring the view in eastern Canada, south through the Pacific Northwest, across the Northern US Rockies section into all of the Northern Plains and across parts of the central/southern Plains. Then eastward into the Mississippi Valley, southeast US and north into the Mid-Atlantic and southern sections of the northeast and finally along the southeast coast out into the Atlantic. DUST: Lesser Antilles/South America… A band of thin Saharan Dust was seen extending over the Lesser Antilles and northern countries of South America and reaching near Central 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
