DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1845Z July 31, 2013
Northwestern and North Central US: A large area of thin remnant smoke extended eastward from the Pacific Northwest/southwest British Columbia across the northern US to the Great Lakes region. The smoke stretched southeastward across the Central US to northern Kansas with an area of moderately dense smoke seen over parts of Nebraska, South Dakota, and Wyoming. The bulk of this smoke has come from fires in the Pacific Northwest states of Oregon, Washington, Idaho, and Montana. Some smoke also has been filtering southward from fires in Canada though and this smoke has mixed in across the north central US. California/Nevada: Thin to moderately dense smoke was present over central California and far western Nevada. This smoke was coming from the Aspen fire in Fresno county, California and was drifting north and northeast. Central & Eastern Canada/Northern Maine: Large areas of remnant smoke were seen across parts of central and eastern Canada including an area that extended across the Labrador Sea. This smoke is believed to be several days old and probably originated from numerous previously burning/smoke-producing fires in northwestern Canada. Alaska/Northwest Canada: Mostly thin smoke covered much of Alaska, the Yukon Territory, northern Northwest Territory, and northern British Columbia. Multiple fires in Alaska and one large fire in the central Yukon Territory are responsible for the remnant smoke. Sheffler 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.osdpd.noaa.gov/ml/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
