DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0100Z July 25, 2021

SMOKE:
Western United States and Canada…
Dense smoke from wildfires in northern California and southwestern Oregon,
in particular the Dixie and Bootleg fires, was observed moving north
and then eastward across much of Oregon, northern Nevada, and southern
Idaho. In addition, numerous wildfires across Washington, northern Idaho,
western Montana, and southern British Columbia were also producing smaller
but still dense individual smoke plumes extending eastward and generally
confined to those regions. However, an area of combined remnant smoke
from these fires, of moderate to high density, extended eastward across
southern Canada and the northern United States at least as far as the
Great Lakes before becoming obscured by widespread cloud cover.

Manitoba and Ontario…
Numerous fires from eastern Saskatchewan to northern Ontario were
producing large plumes of dense smoke extending across much of Ontario
and northeastward over Hudson Bay, as well as Lake Superior and portions
of Michigan’s Upper Peninsula, where the smoke merges with the remnant
smoke from the aforementioned western fires.

Arctic Canada and Alaska…
Fires in northern Yukon and the Northwest Territories were producing
localized plumes of dense smoke which merged with a large area of remnant
smoke extending westward across northern Alaska.

Elsewhere…
Areas of remnant smoke of up to moderate density from the above wildfire
activity were observed across much of the eastern United States and the
northwestern Atlantic Ocean as far east as Newfoundland.


DUST:
Caribbean Sea, Central and Western Atlantic Ocean...
An area of Saharan dust extended from the central tropical Atlantic Ocean
northwestward to Bermuda and the western Atlantic, with an additional
area of dust observed in the eastern Caribbean Sea south of Hispaniola
and Puerto Rico.

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.
