SEND EMAIL RESPONSES TO: SSDFireTeam@noaa.gov. SMOKE: Area from Oregon and California eastward over the Northern and Central U.S. and Southeastern Canada... A large area of very thin density leftover smoke from the Western U.S. wildfires was noted covering a good portion of the Northern and Central U.S. from Montana and Wyoming eastward to the Great Lakes Region and southward from there over the Mid-Mississippi Valley and Central and Southern Plains. Farther to the west, more significant smoke was seen across southern Oregon, northern California, northwestern Nevada, and southwestern Idaho. The thickest smoke was visible over southwestern Oregon and northern California closer to the larger wildfires in that region. In the area covering northern Nevada, southern Idaho, northern Utah, and western Wyoming, it was difficult to distinguish between smoke and blowing dust(see below). DUST: Northern Nevada/Southern Idaho/Northern Utah/Western Wyoming... Blowing dust originated from many point sources in northwestern and northern Nevada as well as southern Idaho and possibly northwestern Utah resulting in a sizable swath of dust which spread over northern Nevada, southern Idaho, northern Utah, and possibly into the western part of Wyoming though it is difficult to differentiate between the dust and smoke from the Western U.S. wildfires. The thickest dust appeared to originate again from the Carson Sink in northwestern Nevada and from another dry lake bed in Churchill County of west central Nevada. Northern Baja... Similar to last night, blowing dust emanated from a source in northern Baja and fanned out as it moved to the north in the general direction of the southern California-Mexico border. JS 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
