DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1800Z July 17, 2016

SMOKE:
Alaska and Northwest/West/Central Canada:
Large amounts of wildfire activity located in North-Central and Central
Alaska contributed to a large area of light to moderate density remnant
smoke which combined with smoke emitted from wildfires in the Northwest
Territories.  This area of remnant smoke spanned from central Alaska
east across Yukon, the Northwest Territories into far northwestern
Nunavut becoming hidden beneath clouds. An expansive ribbon of light
to moderate density remnant smoke (likely originating primarily from
numerous wildfires burning throughout the Northwest Territories) was
also seen extending east southeast across northern British Columbia,
Alberta, western/southern Saskatchewan, and southern Manitoba being
depressed southward towards the US border by a frontal boundary.
In addition over northwest Alaska, some remnant smoke from fires in Asia
appeared to be moving across the Arctic.

Arizona:
The Fuller fire near the Grand Canyon in north-central Arizona was
producing a light moderately density smoke plume which was traveling to
the east-northeast.  Remnant thin to moderately dense/dense smoke from
this fire stretches from northeast Arizona and southeast Utah eastward
to western Kansas/southwest Nebraska.

DUST:
Western and Southern Gulf of Mexico/Southern and Central Plains/Lower-Mid
Mississippi River Valley:
Saharan dust continues to be observed moving north and through the western
and southern Gulf of Mexico with the greatest density over north Texas
into the Central Plains and the Lower-Mid Mississippi River Valley.

North Atlantic/Canadian Maritimes:
Elevated dust likely originating from Africa can be seen over the North
Atlantic lifting northeastward ahead of a frontal boundary just southeast
of the Canadian Maritimes.

Puerto Rico/Caribbean Sea:
Another wave of Saharan dust could be seen moving west over Puerto Rico ,
the Leeward Islands, and over the Caribbean Sea.

West Texas/North Central Mexico:
A small area of aerosol is seen moving west across the northern part of
Mexican state of Chihuahua from western Texas. It seems possible that
this is blowing dust though confidence is not high.

Gulf of Alaska:
A patch of dust is seen over the northern Aleutians and south central
Alaska covering the northern Gulf of Alaska. This dust is likely from
Asia.

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.
