DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z July 6, 2021

SMOKE:
Alaska/Western and Central Canada…
Wildfires across Alaska and British Columbia are helping to produce
a large area of light to moderate density remnant smoke that extends
from Alaska and southern British Columbia and northern Washington
State into the Yukon and Northwest Territories. From there, the smoke
extends east and east-southeastward across Nunavut, northern Alberta,
northern Saskatchewan, northern Manitoba, far northwestern Ontario,
and into Hudson Bay. The thickest smoke was seen moving across central
Yukon into west-central Northwest Territory. Active smoke emissions
of varying density were observed across British Columbia, Alaska,
and the Manitoba/Ontario border region. Smoke from these areas was
generally moving eastward across southern British Columbia, drifting
north-northwestward over central British Columbia, east to northeast
across northeastern Alaska, and southwestward across the Manitoba/Ontario
border region.

Eastern CONUS/Southeastern Canada/Northwest Atlantic…
A layer of thin to moderate density remnant smoke was observed blanketing
much of the eastern CONUS, southern Ontario, southern Quebec, the Maritime
provinces, and out into the North Atlantic. The parent fire activity for
this smoke is the wildfire activity across the Manitoba/Ontario border. A
frontal system has allowed for the detachment of this area of smoke from
the active smoke emissions from that fire activity.

Pacific Northwest…
One wildfire in southeastern Oregon and one located in northern Idaho were
both observed producing moderate to, at times, thick smoke. Smoke from the
fire in Oregon was moving west-southwestward towards and approaching the
Pacific Coast, while the smoke from the fire in Idaho was moving generally
toward the north. Remnant smoke from the Idaho fire was observed as far
east as south-central Montana and northwestern Wyoming.

Mexico…
Light density smoke was observed across the western shore of the Bay
of Campeche, likely the result of gas flaring activity in the Bay of
Campeche as well as agricultural burning across Mexico and Central
America. The smoke was only slowly drifting northward.


Dust:
Eastern Caribbean...
A thin layer of Saharan dust could be seen traveling westward across
the tropical Atlantic and encroaching upon the Windward Islands of
the Caribbean.

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.
