DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0125Z July 17, 2021
SMOKE:
Canada/U.S./North Atlantic/Pacific off the coast of California/Baja...
The extremely large area of varying density smoke remained this
evening and is attributed mainly to very significant wildfire activity
occurring in portions of central/western Canada and the western
U.S. with the exception of a portion of the south central (around Texas)
and southeastern U.S. Smoke also was seen over most of Canada though
eastern Quebec appeared to be relatively smoke free as well as portions
of northwestern Canada. Within this huge mass of smoke were moderately
dense to thick smoke which appeared over a broad region stretching from
the interior portion of the northwestern U.S. and southwestern Canada
eastward over the northern tier of the U.S. and over much of central
Canada. A separate patch of moderately dense smoke extended from the
Mid-Atlantic region over the Northeast and offshore over the nearby
far western Atlantic. Farther to the east, a mass of moderate to thick
density smoke was located over the Atlantic to the south and southeast of
Greenland thinner density smoke extended south of Iceland. Additionally,
some of the thinner density smoke also was barely visible off the west
coast of southern California and Baja.
Alaska/Northwestern Canada…
Wildfire activity mainly in central Alaska was responsible for an area
of thin to moderate density smoke which covered of Alaska and extends
over portions of the Yukon and Northwest Territories.
DUST:
Southern and Eastern Texas/Eastern Mexico/Northern Central America/Gulf
of Mexico/Caribbean Region...
Saharan dust was visible over the western Gulf of Mexico, northern Central
America, southeastern and eastern Mexico, and extending up into southern
and southeastern Texas. A much larger and thicker area of Saharan dust
could be seen east of Puerto Rico and extending to western Africa.

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
