DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1745Z July 7, 2013
Alaska/Canada: The majority of Canada and the central/eastern portions of Alaska are covered by light to very dense smoke this morning, due to numerous wildfires that continue to burn across the region. The light remnant smoke extends from central Alaska eastward across all of the Canadian provinces, across St. Pierre et Miquelon and into the Atlantic Ocean. Embedded within the light smoke are fairly large areas of moderately dense to dense smoke. The first area is located over Alberta/Northwest Territories/Nunavut where the thickest smoke remains along the western/northern side of a surface low pressure system extending northward. The second area of moderately dense smoke is much further east moving across St. Pierre et Miquelon into the Atlantic Ocean. US: An area of moderately dense smoke was visible across portions of the Central Plains and Upper/Central Mississippi Valley regions this morning, intermixing with clouds. This remnant smoke likely originated from the two Nevada wildfires that continue to produce smoke today. An even larger area of light remnant smoke was seen stretching across most of the Southern Plains and Central US across the Great Lakes. Some of the lighter smoke could be due to wildfires in Canada as well as wildfires/agricultural burns in the US. There is also a possibility that the light remnant smoke extended across the Four Corners Region of the US as the smoke continues to wrap around the surface ridge in eastern Colorado, but due to some clouds it was hard to detect. -Vogt 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.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
