DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0130Z September 11, 2017

SMOKE:
Pacific Northwest/Central and Northeastern CONUS/Eastern Canada...
A very large mass of thin density smoke extended eastward from Washington,
Idaho, and Montana to cover virtually the entire Central and Northeastern
US and offshore of the Northeast and Mid-Atlantic. The thinner density
smoke was also present over much of central and eastern Canada. Within
the thin density smoke area, moderately dense to thick smoke was located
covering much of Montana and a portion of the northern and central US from
the Dakotas and the Minnesota/Wisconsin border south to Texas. Moderately
dense to thick smoke also extended north into eastern Manitoba then
east across Hudson Bay into eastern Quebec, southern Labrador, and the
Maritime Provinces. A ridge over Lake Ontario was seen dragging the smoke
south along the coasts of the northeastern CONUS and the mid-Atlantic
then west across the Ohio Valley into the central Great Lakes and north
into Ontario and western Quebec. Thick smoke was observed across much
of Montana, the Dakotas, and eastern Manitoba. The source for much of
this smoke was the ongoing significant wildfire activity occurring over
central and northern Idaho, western Montana, and portions of central
Canada, with contributions from fires in Washington.

California/Baja California/Pacific Ocean
Thin to moderate density smoke from wildfire activity across the Sierras
and Cascades was observed extending westward then southward off the
northern California coast. This extends as far south as the southern
tip of Baja California.

DUST:
Central Atlantic...
Saharan dust was present northeast of the Windward Islands and around
the northern periphery of Hurricane Jose.

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:

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.
