DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z May 22, 2021

SMOKE:
Eastern Canada/Eastern US/Western Atlantic…
Remnant smoke from wildfires across central Manitoba was observed
extending eastward out toward southern Greenland, with some having been
drawn down across the Maritime Provinces, the US East Coast, and the
Sargasso Sea south and west of Bermuda. The smoke is likely to continue
moving east across the North Atlantic, with the drawn down smoke to
be incorporated into a developing cyclone northeast of Bermuda. Due
to extensive cloud cover, wildfire activity could not be analyzed in
central Manitoba. However, continued activity may still be occurring
and would likely be moving south from the parent fires.

Southwestern Canada/Western CONUS…
A likely remnant area of moderate density smoke was observed extending
from western Oregon northeastward into north-central Saskatchewan. Due to
extensive cloud cover, the parent fire is not clear, but two persistent
fires in southern Nevada could be to blame. These two fires were active
yesterday and are actively producing moderate density smoke today.

Southern Mexico/Central American Pacific Coast…
Widespread fire activity across southern Mexico and scattered activity
across northern Central America, along with remnant smoke from widespread
activity over the same areas over the past few days, were all contributing
to a thin to moderate density layer of smoke blanketing much of the
Pacific Coast of Mexico and Guatemala, southern and eastern Mexico,
the western Gulf of Mexico, and the Bay of Campeche.


DUST:
Caribbean...
A thin density plume of Saharan dust covers the central and eastern
parts of the Caribbean Sea.

Four Corners…
Strong south-southwesterly wind were observed transporting dust from
northeastern Arizona and eastern Utah across these areas, as well as
far western Colorado and southwestern Wyoming. Dust is being transported
nearly 400 miles from near the Mogollon Rim to the Uinta Mountain Range
just south of the Utah-Wyoming Border. Another stream of dust was observed
emanating north-northeastward from Sevier Lake in west-central Utah.

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
