DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z August 1, 2017

SMOKE:
Area from Southwestern Canada to Eastern Canada and the Northeastern
US/Area from Northern California, Oregon, and Washington to the North
Central US...
A combination of wildfire activity scattered over southern Canada from
southern British Columbia to Ontario and wildfire activity over northern
California, Oregon, Washington, Idaho, and western Montana was responsible
for 2 large masses of smoke which merged near the North Central US-South
Central Canada border and continued to spread to the east. The leading
portion of the thin density smoke extended as far east as Quebec and
northern New England. Moderately dense to thick smoke blanketed the area
from southern British Columbia to southern Manitoba and from northern
California and southern Oregon to North Dakota. Very dense smoke was
seen just prior to sunset emanating from the fires in southern British
Columbia, western Montana, central Idaho, northern and northeastern
Washington, and northeastern California.

Alaska/Northern Yukon...
Fires over central, eastern, and northeastern Alaska are producing a
region of light density smoke which moved to the east and northeast over
the northern Yukon and the northern part oft the Northwest Territories

Northwest Territories...
Fires scattered over the western and norther part of the Northwest
Territories are responsible for a mixed density smoke layer over that
portion of the province though some of the leftover thin density smoke
from the eastern Alaska fires has moved to the east and is affecting this
area as well. Farther to the south, fires flared again over the southern
Northwest Territories resulting in numerous significant smoke plumes
which spread to the south into northeastern Alberta and northwestern
Saskatchewan.

DUST:
Puerto Rico...
The leading edge of an area of Saharan dust was visible this afternoon
and early evening moving over the Windward/Leeward Islands, the Virgin
Islands, and Puerto Rico.

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.
