SEND EMAIL RESPONSES TO: SSDFireTeam@noaa.gov. SMOKE: Western CONUS... Wildfires across southwestern Oregon and the Ferguson Fire in central California were observed producing thick smoke. The smoke from the wildfires in Oregon has created a blanket of thick smoke filling valleys from extreme north-central California into much of southwestern Oregon. The lighter smoke making it out of the valleys has spread out over the rest of Oregon and central Idaho. The smoke that is lofted will continue to spread out to the north and east. As for the Ferguson Fire, much of the smoke, which varies in density, remains confined to the eastern rim of the San Joaquin Valley, with some thicker smoke near the wildfire finding a few valleys through which it can pass towards the east. A very small portion of the smoke has made its way over and the Sierras and into Nevada, with some making its way around the Sierras to the north. This area of smoke will likely spread along the Sierras to the north and south unless the smoke can top the Sierras. Great Lakes and Eastern Canada... A layer of moderate to thick smoke was observed over central Quebec into Ontario and wrapping around a cyclone over the Great Lakes into the UP of Michigan, Wisconsin, northern Illinois, and northern Indiana. The source of this probably remnant smoke layer is likely wildfire activity across eastern Ontario south of James Bay over the last few days. Northern, Western, and Southwestern Canada... A very large area of varying density smoke was observed over the northern tier of Canadian Provinces wrapping around a cyclone in central British Columbia, after which the smoke extends into Alberta, central Saskatchewan, and central Manitoba, where another cyclone is incorporating the leading edge of the smoke layer. This smoke is believed to be long range transport across the Arctic Ocean from fires in Russia/Asia. DUST: A dense SAL was observed across the southeastern North Atlantic extending out from west Africa. This is slowly drifting north and west. 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/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
