DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1745Z August 07, 2012
Most of the US: A large area of thin-density smoke was visible this morning in satellite imagery. The smoke stretched across the majority of the US extending from Washington/Oregon eastward through the Great Lakes/Quebec, Canada and southward across Texas. Medium-density was also present over a portion of Washington/Oregon, southern Idaho, and all of Wyoming. This thin-to-medium density smoke is caused by the numerous wildfires located across the Idaho/Nevada region that continue to emit immense amounts of smoke. Detection of the full extent/coverage of the smoke was inhibited by some clouds. Northwest Territories/Alberta/Saskatchewan/Manitoba: An area of thin-density smoke could be seen across the south-central Canadian provinces this morning traveling eastward. A wide swath of medium-density smoke was also present wrapping into the surface low across the Northwest Territories/northern Alberta/northern Saskatchewan. This entire area of remnant smoke is likely due to the wildfires that continue to burn in the area. However, a portion of the smoke could also be attributed to Siberian smoke. -Vogt- THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT AREAS 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
