DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z October 5, 2021

SMOKE:
Eastern Canada…
An area of thin density smoke likely attributed to the wildfires in
eastern Saskatchewan was seen this morning over portions of far eastern
Canada and over part of the Labrador Sea.

U.S./Southern Canada/Northern Mexico/Gulf of Mexico/Far Eastern Pacific
off the California and Mexico Coastline…
Areas of smoke due, primarily to ongoing wildfires in east central
California, as well as Idaho, western Montana, and eastern Saskatchewan,
covered sizable portions of the U.S. and southern Canada this morning. In
particular, a band of moderate to thick density smoke was seen stretching
from central California to the northeast over the northern Rockies
to central and eastern Montana. From there, the thicker band of smoke
extended to the northeast and east across southern Canada from central
and southern Saskatchewan eastward to southern Hudson Bay and western
Quebec. The thicker smoke which stretched from central California to
eastern Oregon and Idaho was due mainly to the larger wildfires burning
in the southern Sierras of east central California while some of the more
significant smoke across Montana and into Saskatchewan was due to the
wildfires in Idaho and western Montana as well as from the California
fires. Finally, farther to the north and east, the thicker smoke across
south central and southeastern Canada was likely mainly from the larger
wildfires in eastern Saskatchewan though some contribution from the Idaho,
western Montana, and California fires may also be present.

DUST:
Atlantic…
The area of Saharan dust which had been over a portion of the Caribbean
region appears to have shifted north of Puerto Rico and Hispaniola.

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.
