DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z July 27, 2023

SMOKE:
Canada/United States/Atlantic Ocean/Northern Mexico/Pacific Ocean off
the U.S. West Coast/Northern Gulf of Mexico…
Heavy, dense smoke from fires in northwestern Canada was observed across
northern Alberta and British Columbia, as well as much of Northwest
Territory and the Yukon. Moderate smoke extended from eastern Alaska to
northern Nunavut. Additional moderate smoke, presumed to be mostly from
the same fires, also extended across the northwestern U.S. and border
regions of Canada, extending eastward and southward across much of the
eastern half of the U.S. except for Florida and New England. The area
of light smoke extended from Eastern Alaska across the whole of Canada
and much of the U.S. except California, Nevada, and smaller portions
of the mountain west. This area also extended down across the coastal
regions of northern Mexico, where it is presumed that it mixed with
remnant smoke from local seasonal burning.

Pacific Northwest…
Several fires in the region, notably in western Oregon, central Idaho,
and western Montana, were observed to be producing smoke plumes of up to
heavy density, although the smoke was remaining localized to the region.

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.
