DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1815Z July 4, 2016

SMOKE:
Northwestern to South Central Canada:
An extensive area of light density remnant smoke from fires in the
Northwest Territories, northern Saskatchewan, northern Alberta, and
northern Manitoba extends southeastward from northwest Nunavut to
southeast Ontario/southwest Quebec. Moderately dense to dense smoke is
especially prevalent over the Northwest Territories directly north of
the bulk of the fire activity.

North Utah/Northwest Colorado/South Wyoming:
An area of moderately dense to dense smoke has moved from northern Utah
eastward today crossing southern Wyoming and northwest Colorado. This
remnant smoke is primarily from the Hot Pot brush fire in west-central
Elko county Nevada. However, two smoke producing fires in the Sierra
Nevada yesterday may have also contributed to this area of smoke.

North Dakota/Northwest Minnesota/Southern Manitoba:
An area of thin remnant smoke observed over eastern North Dakota,
northwest Minnesota, and southern Manitoba is likely from the brush fire
in Nevada.

Alaska:
Remnant smoke is seen from the northern coast of the Alaska stretching
northeast across the Arctic waters and ice. In addition a small patch
of thin smoke is observed off the west coast of Alaska between areas
of cloud cover. All of this smoke is primarily believed to be from
Siberian wildfires.

DUST:
Eastern Caribbean/Bahamas/South Florida/Southeast Gulf of Mexico/Western
Atlantic:
An expansive area of optically thick Saharan dust can be seen pushing
westward across almost the entire Caribbean Sea from the Leeward Islands
to just east of the Yucatan Peninsula. The dust extends north across
Hispanola and eastern Cuba over much of the Bahamas and into part of the
western Atlantic. Saharan dust can also be seen spreading west across
southern Florida and the southeastern Gulf of Mexico.

Western and Northern Gulf of Mexico/Southern Plains/Lower Mississippi
River Valley/Southeast US:
A broad area of aerosol that is believed to be mostly African dust is
present across the western and northern portions of the Gulf of Mexico
extending inland across central Texas/far southern Oklahoma, the Lower
Mississippi River Valley, and much of the Southeast US disappearing
beneath cloud cover over North Carolina. Other aerosols including a small
amount of remnant smoke may be mixed with the elevated dust. Remnant
smoke coming from Mexican oil rigs in the Bay of Campeche could be seen
over the western Gulf as well.

Central Nunavut:
A swath of aerosol thought to be elevated dust is seen moving west along
the northwestern shore of Hudson Bay becoming mixed with the extensive
area of remnant smoke over northwest Canada. The origin of the dust is
not known.

UNKNOWN AEROSOL:
Northeast US/Canadian Maritimes:
A faint aerosol is seen moving off the coast of the Northeastern US states
and across Nova Scotia, Newfoundland, and the Gulf of St. Lawrence. While
the composition of the aerosol can not be fully determined, it seems
plausible that this could be remnant smoke from the wildfires in Canada,
possibly mixed with other unknown aerosols.

Great Lakes Region:
An area of aerosol is observed moving northward across far northeast Iowa,
southeast Minnesota, Wisconsin, Lake Michigan, Michigan, and Lake Superior
towards southern Ontario. There is a possibility that this aerosol is
dust although it is uncertain if this is the case given the wide array
of aerosols and sources across the United States today.

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.
