DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z June 25, 2021
SMOKE:
Southwestern and South Central U.S./Middle and Lower Mississippi
Valley/eastern Ohio Valley…
A large mass of rather thin density smoke primarily attributed to
wildfires in the Southwestern U.S. was seen this morning over portions
of the Southwestern, Central, and South Central U.S. as well as the
Middle and Lower Mississippi Valley and extending as far east as parts of
eastern Ohio, eastern Kentucky, and western West Virginia. Cloudiness was
widespread from eastern Montana and Wyoming across the North Central and
Central U.S. to the eastern Great Lakes region which prevented information
on the extent of the smoke in these areas from satellite imagery. Areas of
thicker density smoke were visible closer to and extending to the east
and southeast from the Rafael Fire in central Arizona and the Horton
Complex and Bear Fires in eastern Arizona.
South Central Canada/Northern Minnesota...
A west to east elongated swath of thin to moderate density smoke likely
from wildfires in central Saskatchewan was visible stretching from eastern
Saskatchewan across central Manitoba to western Ontario. A bit farther to
the southeast, another west to east elongated area of thin to moderate
density smoke attributed to wildfires in southwestern Ontario was seen
across northeastern Minnesota and southern and eastern Ontario.
Alaska and Northwestern Canada...
Wildfires were still visible in satellite imagery in between breaks in
the clouds early this morning in central Alaska and the northern Yukon
in northwestern Canada though cloud cover prevented much in the way
of smoke detection across the region. A possible patch of thin density
smoke attributed to the wildfire in the northern Yukon was seen moving
to the east over the northern portion of the Northwest Territories.
Northwestern Mexico…
An area of thin to moderate density leftover smoke likely from fire
activity over western and northwestern Mexico was visible this morning
over a portion of northwestern Mexico and the Gulf of California.
Western Atlantic…
A possible remnant thin density patch of smoke was present over the
Atlantic due east of the Mid-Atlantic coast and due south of Nova
Scotia. The source of this possible smoke was not known as it is likely
been suspended aloft for many days.
DUST:
The Saharan dust which was visible recently in the Gulf of Mexico was
no longer seen in satellite imagery this morning.

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
