DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1600Z September 28, 2021

SMOKE:
United States and South Central Canada….
A large area of smoke from the western United States wildfires extended
from southeast Canada and coastal New England west through sections
of the eastern United States, most of the central United States west
to the fire activity over the western United States and then offshore
southern California and the northern Baja. Within this larger area
of smoke, several areas of moderate to high density smoke were seen.
Those being from fire activity over central California northeast through
the northern Rockies and extending into the northern Plains and far south
central Canada.  The moderate to high density smoke also extended south
through southeastern California, western Arizona, far northwestern Mexico
and offshore southern California and the northern Baja.  Another area of
moderate density smoke was seen over the portions of the southwestern
United States and southern Plains from western Texas and eastern New
Mexico northeast to southeastern Colorado and southwestern Kansas.

DUST:
Tropical Atlantic Ocean….
A large area of Saharan Dust was extended through much of the eastern and
central Tropical Atlantic Ocean to just east and north of Hurricane Sam.

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.
