DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1745Z July 11, 2012
Northern and Central Canada: Multiple large wildfires continue to burn across northern Alberta and northern Manitoba this morning. Remnant smoke from these fires extend from the Northwest Territories southeastward into Ontario. The thin-density smoke has the furthest extension, while medium-to-thick density smoke is present across northern Alberta/Saskatchewan moving mainly eastward behind a low pressure system and associated cold front. Clouds associated with the low pressure system hindered detection of the full extent of the smoke in this area. Pacific Northwest/Central US/into Ohio Valley: Wildfires burning across the Pacific NW/Idaho continue to emit large amounts of smoke today. An area of medium density smoke is present from southeast Oregon/Idaho into northern Wyoming, and traveling eastward over the surface ridge. Elsewhere, thin-density smoke is present but is also likely mixed in with some sulfates due to high pressure dominating most of the US. -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
