THROUGH 0300Z August 15, 2010
Washington: Dry conditions and an easterly wind have caused old volcanic ash from Mount St. Helens to be resuspended. The ash is being carried approximately 70 miles to the northwest of the summit. Pacific Northwest and southwest British Columbia: Numerous wildfires continue to rage over west central British Columbia and generate a large area of moderately dense to dense smoke which is moving to the west into the Pacific then take a more southerly track west of the Washington and Oregon coasts. This area of smoke extends over 700 miles from the origin of the fires in British Columbia. Sierra Nevada Mountains of California: Several fires were noted in the central Sierra producing light to moderately dense smoke. Eastern Canada: Remnant smoke can still be seen off the coast of Nova Scotia in evening imagery. This ares of light smoke is slowly drifting southwest. Yukon: Several wildfires in southeast Yukon continue to produce moderately dense to dense plumes of smoke that are moving southeast across northeastern British Columbia, Alberta and into Minnesota. MS 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
