DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1830Z April 17, 2010
Southeast US: Thin to moderately dense residual smoke could be seen this morning over parts of Georgia, South Carolina, and North Carolina stretching eastward along a frontal boundary across the western Atlantic. Another area of thin smoke with embedded moderate densities had become separated over north Louisiana/south Arkansas. The leftover smoke is believed to be from fires in the southeastern US and TN valley over the past day or two. South Central Canada/Northern Great Plains to Ohio Valley: A plume of aerosols likely to contain remnant smoke was seen stretching from northern Saskatchewan/northern Manitoba southeastward into the North Central US and reaching as far as western Ohio. The overall composition of the plume, especially in central Canada is unknown,as well as the origin. But given the numerous fires that were identified yesterday over the Northern Plains and South Central Canada, and the fact that smoke is most dense just downstream of those regions, it is believed smoke makes up a good portion of the aerosol composition. Moderately dense smoke covered from western Ontario across Minnesota, Wisconsin, Illinois, southwest Michigan, Indiana, and northwest Ohio with dense smoke over southern Lake Michigan. -Sheffler THE FORMAT OF THIS TEXT PRODUCT IS BEING MODIFIED. IT WILL NO LONGER DESCRIBE THE VARIOUS PLUMES THAT ARE ASSOCIATED WITH ACTIVE FIRES. THESE PLUMES ARE DEPICTED 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 THIS TEXT PRODUCT WILL CONTINUE TO DESCRIBE SIGNIFICANT AREAS OF SMOKE WHICH HAVE BECOME DETACHED FROM AND DRIFTED SOME DISTANCE AWAY FROM THE SOURCE FIRE, TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. IT WILL ALSO STILL INCLUDE DESCRIPTIONS OF BLOWING DUST. ANY QUESTIONS OR COMMENTS REGARDING THESE CHANGES OR THE SMOKE TEXT PRODUCT IN GENERAL SHOULD BE SENT TO SSDFireTeam@noaa.gov
