DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z August 2, 2019

SMOKE:
Alaska/Canada/Northern Plains/Great Lakes...
Both a large area of both remnant smoke from Russian wildfires and large
smoke plumes across northern Canada were helping to create a layer of
thin to moderate density smoke that extended across Alaska, Canada, the
Great Lakes, the North Atlantic, and presumably into Europe. Cloud cover
across much of Alaska and portions of central Canada may obscure any
smoke plumes across these areas. The heaviest smoke was located across
the Northwest Territories, and from an intense and persistent wildfire
across the northwestern Northwest Territories.  The smoke from this fire,
along with a number of other fires across the Northwest Territories,
was observed moving northeast. The large area of remnant smoke was
moving generally east, with some deviations based on ridges and troughs
in upper-atmospheric flow.

Northwestern CONUS...
The Milepost 97, the Left Hand, and the Devore Creek fires, along with
another unnamed fire in northwestern Oregon, were all producing moderately
dense to thick smoke plumes this afternoon. These smoke plumes were
observed moving north to northeastward. Remnant smoke was also noted
extending from around the Milepost 97 Fire northeastward into southern
Canada, where it appeared to be merging with the large area of remnant
smoke noted above.


DUST:
Eastern Caribbean...
A thin region of Saharan dust was observed across the eastern Caribbean
and the area of the Atlantic Ocean north of the Caribbean. This area
of Saharan dust was slowly moving off toward the west into the central
Caribbean.

Central Atlantic...
A thicker layer of Sahran dust was observed moving east across the
Atlantic from south of 30N, east of 55W, and west of 25W.

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.
