DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z July 8, 2021


SMOKE:
Canada...
Wildfires across the Manitoba/Ontario border region and British Columbia
are helping to produce a large area of light to moderate density smoke
that extends over most of Canada from British Columbia and northern
Washington State into the Yukon and Northwest Territories. From there,
the smoke extends east across Nunavut, northern Alberta, Saskatchewan,
Manitoba, Ontario, across Hudson Bay ad into northern Quebec. Active heavy
smoke emissions were observed from wildfires across British Columbia
and the Manitoba/Ontario border region. Smoke from these areas was
generally moving east-northeastward across central British Columbia and
east-northeastward across the Manitoba and Ontario, respectively. Some
remnant smoke from the Manitoba-Ontario border region was seen across
the Mississippi Valley as well.

Northeastern US/Maritime Canada/North Atlantic…
Light remnant smoke from likely both main Canadian sources above was also
observed extending east-northeast from the Mid-Atlantic and northeastern
CONUS across the Canadian Maritime Provinces and into a cyclone exiting
the Labrador Sea. Some of this smoke may possibly be making its way
further east across the North Atlantic, but widespread cloud cover
inhibits the ability to analyze smoke there.

Pacific Northwest...
Wildfires across northern California, Oregon, and Idaho have been and
are still producing moderate to thick smoke. The smoke from these fires
was seen extending into northern Wyoming and Montana. Remnant smoke
from these fires was observed wrapping around the eastern periphery
upper high over the western CONUS. This would include western Nebraska,
the Texas and Oklahoma Panhandles, and southern new Mexico.

Southeastern California and southwestern Arizona…
Remnant smoke from yesterday’s fire activity was observed across
portions of the desert southwest. The smoke had settled into the lower
areas of southwest Arizona and southeast California.

Eastern CONUS/Southeastern Canada/North Atlantic...
A layer of thin to moderate density remnant smoke was observed
blanketing an area extending from Texas and Oklahoma into the Ohio
Valley and Mid-Atlantic. From there, the layer of smoke is being drawn
east-northeastward along a front into portions of the Maritime Provinces
and the North Atlantic. The parent fire activity for this smoke is the
wildfire activity across the Manitoba/Ontario border.


BLOWING DUST:
Central and Eastern Caribbean...
A layer of moderate density to thick Saharan dust could be seen
traveling westward across the eastern Caribbean, eastern Bahamas, and
the southwestern Sargasso Sea. The western edge extends across Jamaica,
eastern Cuba, and the eastern Bahamas, with the eastern edge a few
hundred miles east of the Windward Islands.

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.
