DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0132Z July 31, 2021
Canada/U.S... The expansive area of varying density smoke remained this late afternoon. The smoke is attributed to significant wildfire activity in central, south central, and southwestern Canada, along with the northwestern and western CONUS. Smoke continues to be observed covering an area extending from the Pacific Northwest into and across almost all of Canada, where the fire activity in east-central Manitoba and western Ontario adds to the area of smoke. Following a ridge, light smoke covers the NW US, much of Canada and the high plains of the US before diving down over the Midwestern US, Mississippi valley, Great Lakes and continues east across the Ohio Valley, southeastern US, and mid-Atlantic region where it exited into the western Atlantic. Light smoke extended northeast in the Atlantic Ocean off of a majority of the east coast and moving all the way towards the coast of Newfoundland. Medium density smoke covered most of the western US and Canada as well as the high plains and mid-west. A very large amount of dense smoke was also observed from British Columbia and extended to the east over south central to eastern Canada and then to the south and southeast over roughly the northern portion of the country through the eastern part of the U.S. Hawaii... In northern Hawaii a moderate to heavy density smoke plume attributed to wildfires was observed moving west. DUST: Lesser Antilles/Central America/South America… A band of thin Saharan Dust was seen extending over the islands and into Central America and northern countries of South America. 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
