DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z July 31, 2017
SMOKE: Southern Canada into Hudson Bay... A fairly large region of mixed density smoke is analyzed over southern Canada into the Hudson Bay region. This region of smoke has its origins in southern British Columbia, where a large complex of fires continues to burn. The easternmost portion of the smoke plume is of light density. This smoke has been ingested within a cyclone currently over far eastern Manitoba. Over southern Saskatchewan, southern Alberta, and west-central Manitoba, the smoke plume is of moderate density. Nearest the source region in southern British Columbia and portions of southern Alberta, the smoke is quite dense. Northwestern US... Active fires throughout the northwestern United States are producing light to moderate smoke plumes. Much of the plume is tenuous in nature, but over northern California, south central Oregon, and much of Montana, moderately thick smoke plumes are seen emanating from specific fires. Elsewhere throughout the northwestern United States, the smoke is more remnant, such as over eastern Washington state and the northern part of the Nevada-Utah border. Alaska/Northern Yukon... Fires over northeastern Alaska are producing a light smoke plume throughout northeastern Alaska and the northern portions of the Yukon Territory. Northwest Territories... Fires throughout the Northwest Territories are spawning a mixed density smoke layer over the central Northwest Territories. Much of the layer is light density, but a seemingly remnant layer of moderate density smoke can be observed within the region of lighter smoke. -Hosley 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.ospo.noaa.gov/Products/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
