DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1530Z July 16, 2009
Alaska/NW Canada to US Great Lakes: A large area of smoke from numerous fires in NE AK and S Yukon Territory continues to cover nearly all of NW Canada including all of the NWT, continental Nunavut, Alberta, Saskatchewan and western 2/3rds of Manitoba. The smoke also leaks into NE ND, N MN and then consolidates on the south side of the upper low covering much of WI, the UP of MI and Lake Michigan. A large are of moderate to dense smoke from PyroCbs likely over the last 2 days as the smoke is generally higher in altitude and has an anticyclonic curl to it on the mesoscale ridge across N Saskatchewan, ext. NE Manitoba and S Nunavut. Thin smoke can be seen rotating back south across the Arctic sea into NE AK because of the flow of the large, well defined cyclone over Big Bear Lake. This cyclone is also pulling the thin smoke across the Yukon into its center...though there is a break of “clearer” sky just behind the cold/occluded front separating the 2 areas described. N Nevada/S Idado: A pocket of thin smoke from the Trailer 1 and RedRock fires. The smoke is bowing out into a crescent shape covering SW ID and NE NV about to move into NW UT. Gallina More information on the areas of smoke described above as well as others can be found at the locations listed below. 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.ssd.noaa.gov/PS/FIRE/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
