DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1630Z September 5, 2017
SMOKE: Continental US/Southeastern Canada/Southern British Columbia... An expansive area of mostly moderate to dense smoke was seen spanning much of the CONUS and southeastern Canada from the Pacific Coast to New England and the Maritime Provinces. The smoke covers most of the Pacific Northwest and southern British Columbia and extends east-southeastward across Wyoming, Colorado, and central and southern Great Plains. The region of smoke continues east through the Ozarks then east-northeast through the Ohio River Valley and New England. The source of this plume is the ongoing wildfire activity throughout the western CONUS and southern British Columbia. This region of smoke was also seen to be sagging southward at the time of analysis. Central Canada... A cluster of wildfires in east-central Saskatchewan were producing a plume of light to moderate smoke that extended to the south-southeast across the Manitoba/Saskatchewan border into northeastern North Dakota. A relatively small patch of remnant smoke over eastern Manitoba and far western Ontario was also seen merging with the light density smoke plume over eastern North Dakota and western Minnesota. After merging, the region of light density smoke extends southeastwards over eastern South Dakota, Iowa, southern Wisconsin, and northern Illinois. Pacific Ocean/Northern British Columbia... An area of varying density smoke from wildfires throughout Washington, Oregon,and California extends off the coast to about 135W. Closer to the coast and nearest the wildfires, thick smoke is being drawn out over the Pacific by a cyclone off the California coast. Most of this dense smoke is being blown off tho the north, but some is forming a less dense region of smoke incorporated within the cyclone. Further offshore, remnant smoke can be seen covering an expansive area from a weak cyclonic feature around 27N, 132W north into northern British Columbia around the western periphery of the cyclone off the coast of California. Hosley 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/Products/land/hms.html GIS: http://www.firedetect.noaa.gov/viewer.htm KML: http://www.ssd.noaa.gov/PS/FIRE/kml.html ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO SSDFireTeam@noaa.gov
