DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0145Z September 17, 2020
SMOKE:
Eastern Pacific/Much of Lower 48/Northwestern Mexico/Southern
Canada/Atlantic off the Mid-Atlantic, Northeast, and Canadian Maritimes…
Smoke analysis remained primarily unchanged throughout the evening with
the exception of the expansion of smoke into the Pacific as it wraps into
weather systems off of the coast. Light smoke also expanded further
north into Canada and Newfoundland. An additional area of light smoke
and/or Saharan dust was visible spanning from portions of Cuba and the
Florida peninsula into the Gulf of Mexico over the Yucatan peninsula
and Bay of Campeche. As smoke analysis from earlier today stated,
more exceptionally widespread smoke from the ongoing large wildfires
in the Western U.S. continued to be visible across portions of the
eastern Pacific, much of the lower 48 (with the exception of the region
from eastern Texas to South Carolina, Georgia, and Florida), southern
Canada, northwestern Mexico, and over the Atlantic off the coast of the
Mid-Atlantic, the Northeast, and the Canadian Maritimes. Thicker smoke
covered an unusually large area including virtually all of the Western
U.S. though it gradually thinned out to moderate density over portions
of the Southwest. Thicker smoke also extended east over roughly the
northern half of the lower 48, southwestern and southeastern Canada,
to off the coast of the Mid-Atlantic, Northeast, and Canadian Maritimes
where it became entrained into the circulation of the former tropical
system named Paulette.
DUST:
Areas of Saharan dust were visible over the central and eastern
subtropical portions of the Atlantic with some thinner density Saharan
dust edging into the Caribbean Sea and surrounding islands.

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
