THROUGH 0300Z September 20, 2012
Pacific Northwest: Areas of heavy dense smoke have expanded throughout the day across the area. Areas with heavy dense some include from northeastern Nevada into eastern Oregon, much of central Washington and northwest Oregon, as well as central Idaho and western Montana. From earlier today: Pacific Northwest to western Gulf Coast: Large wildfires continue to burn in Oregon, Washington, Idaho, Wyoming and Montana creating a broad area of new and remnant smoke. The light density smoke extends from the Pacific Northwest across much of Wyoming, eastern Utah and Colorado before being steered south across the central plains and into central Texas. There are extensive areas of moderate density smoke in the immediate vicinity of the fires. Canada: A handful of fires in central and northeast British Columbia and extreme northwest Alberta are producing smoke this morning that mainly extends east and southeast in elongated plumes. Smoke remains visible for a few hundred kilometers before dissipating. Liddick 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
