DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z August 24 2015

SMOKE
Western/Central US and Western Canada to the Tennessee Valley and
Great Lakes:
An enormous amount of smoke from the wildfires that continue to burn
in California, Oregon, Washington, Idaho and western Montana was seen
stretching across most of the US. Smoke covers all of the Pacific
Northwest and northern Rockies and then dips into the Central Plains as
far south as northern Texas. It continues into the Tennessee and Ohio
Valleys and then curls to the north into the central Great Lakes. The
area of central Tennessee and northern Alabama is likely mixing with or
predominantly sulfates. The smoke also has slid south along the eastern
slopes of the Rockies into eastern New Mexico. The heaviest smoke,
which is moderate to dense, was seen covering northwest California,
nearly all of Oregon, Washington and Idaho and into western Montana
and northwest Wyoming. Smoke was also being drawn north into southern
British Columbia although the full extent of the smoke was difficult to
determine due to more extensive cloud cover.

Smoke from the Rough fire in the central Sierra Nevada of California was
spreading to the northeast into Nevada and northern and central Utah
and merging with the smoke from the fires further north. The areas of
moderately dense and dense smoke were mainly over the Sierra and to the
east to the Nevada border and into west central Nevada.

Central/Eastern Canada:
A large area of remnant smoke originating from the wildfires in the
western US is visible over a large portion of eastern Canada. It covered
James Bay into southern Hudson Bay, all but far northern and far southwest
Quebec and continued east across the southern half of Newfoundland and
Labrador and the northern Gulf of St Lawrence before heading into the
open Atlantic. A large portion of this mass was moderate to dense.

DUST
Caribbean:
A surge of Saharan dust was seen across the southern Caribbean this
afternoon and evening. The dust has reached the Gulf of Honduras along
the Central American Coast.

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.
