DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0040Z September 20, 2023

SMOKE:
Canada, Central United States, Eastern United States, Pacific Northwest
United States, North Atlantic Ocean, northern Gulf of Mexico and Pacific
Ocean off of Oregon and northern California….
Persistent and ongoing wildfire activity across western Canada is
continuing to produce a large amount of moderate and high density smoke
that extends from northern British Columbia and northern Alberta into the
eastern Northwest Territories and extending east and northeast from there
across much of northern and central Canada to portions of Baffin Bay.
A larger area of thin density smoke, from the Canadian fires, was seen
over most of Canada, much of the Central and Eastern United States,
over a portion of the North Atlantic Ocean, much of the Gulf of Mexico,
northern Mexico and the eastern Pacific Ocean.  Fire activity over
northern California and the Pacific Northwest was also producing an area
of mostly light to moderate density smoke that was seen over much of the
Pacific Northwest and merged with the larger area of smoke over portions
of southern Canada.  Localized high density smoke was also observed with
the fires in northern California and southern Oregon.

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:

ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO:

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.
