DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0330Z July 22, 2016

SMOKE:
Western US to North Central US:
Areas remnant thin density smoke with embedded patches of moderately dense
smoke remained visible spreading generally to the east and northeast from
southeast Idaho/western Wyoming eastward across the North Central US to
at least as far east as Wisconsin. The smoke is attributed to a number
of wildfires burning over the western US especially those over western
Wyoming, southern Idaho, and central Nevada. Many of these same fires
continued to produce fresh plumes of moderately dense to dense smoke
this evening.

Gulf of Mexico:
A small patch of thin remnant smoke likely from fires in the Southeast
US yesterday was moving west over the western Gulf.

Southwest US/Northern Baja California:
An area of thin smoke covers the US/Mexico border separating California
and Baja California with remnant smoke drifting over far southwest
Arizona. Much of this smoke is from a large wildfire in northern Baja
though Mexican agricultural burning also contributed some smoke.

Southeastern Canada/Northeastern US:
Leftover thin to moderately dense smoke attributed to recent wildfire
activity in western Canada and Alaska continued to be visible spreading
to the south and east across far southeastern Canada, the coast of
the Northeast US, and offshore over the North Atlantic. Some areas
of thin smoke were also present near Newfoundland and over eastern
Quebec/Labrador.

South Central/Central Canada:
Pockets of remnant thin smoke are seen this evening from eastern
Alberta/Saskatchewan eastward across southern Canada and over
Ontario. Additional pockets of thin to moderately dense smoke exists over
and just east of Hudson Bay. This smoke is believed to be from recent
wildfire activity in western Canada. Cloudiness north and northwest of
this region including over locations of the recent wildfires inhibited
smoke detection from satellite imagery through a good deal of the region.

DUST:
Oregon:
Blowing dust could be seen spreading northeastward across central Oregon
this evening originating from the vicinity of Summer Lake in the southern
part of the state. The dust was visible from about 22Z through 03Z before
the loss of daylight.

Southeast US Coast:
Aerosol present along the coast of the Carolinas, Georgia, and northern
Florida is believed to be elevated dust, likely of an African origin.

Western Atlantic/Caribbean:
Saharan dust was seen over the western Atlantic spreading westward
across the Leeward Islands, the eastern Caribbean, Puerto Rico, and the
Dominican Republic.

UNKNOWN AEROSOL:
Great Lakes Region/Ohio Valley/Mississippi Valley/Southern Plains:
An aerosol composed of unknown pollutants was seen from portions of the
Great Lakes Region southward over the Ohio Valley and Mississippi Valley
extending as far southwest as southern Texas. Some smoke and dust may
be mixed in with this aerosol though that is not a certainty.

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.
