DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z August 25, 2017

SMOKE:
Canada/Far Northern US...
As has been the case for a number of days now, a significant batch of
moderately dense to thick smoke covered a sizable part of Canada from
Alberta and the eastern half of the Northwest Territories eastward to
northern Quebec. The moderately dense smoke also spread southward over
Lake Superior and the U.P. of Michigan by late in the afternoon. This
long lived area of smoke is leftover from wildfire activity especially
over central and southwestern Canada though some smoke from the fires
in the Northwestern US is also likely involved.

Large area from the Northwestern US to the Mid-Atlantic and Northeastern
US...
An expansive region of thin density smoke stretches from along the coast
of northern California and much of Washington and Oregon eastward over
the northern and central Rockies, the Northern and Central Plains,
the Great Lakes region, the Ohio and Mid-Mississippi Valley regions,
the Mid-Atlantic region, and the Northeast. Moderately dense to thick
smoke extended from northern California and southwestern Oregon to the
Dakotas. The thicker smoke in the region from northern California and
southwestern Oregon to the Dakotas was primarily attributed to numerous
wildfires burning over western Montana, central Idaho, Washington, central
and southwestern Oregon, and northern California. The smoke farther to the
east over the central and eastern US is likely from a combination of the
fires over the northwestern US as well as central and southwestern Canada.

DUST:
Caribbean...
An area of Saharan dust continued to spread very slowly to the west and
appeared to be in the vicinity of Puerto Rico, Hispaniola, the southern
Bahamas, Cuba, and at least some of the Caribbean though cloudiness
during the day made detection difficult

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:

ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO

Unless otherwise indicated:
  • Areas of smoke are analyzed using GOES-EAST and GOES-WEST Visible satellite imagery.
  • Only a general description of areas of smoke or significant smoke plumes will be analyzed.
  • A quantitative assessment of the density/amount of particulate or the vertical distribution is not included.
  • Widespread cloudiness may prevent the detection of smoke even from significant fires.
