DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1632Z September 20, 2021

SMOKE:
Southwestern/Central U.S., and Mexico/Pacific...
An area of mostly light density smoke primarily due to the ongoing
wildfires burning in the western U.S. continued to be seen today extending
from over the far eastern Pacific off the U.S. west coast inland and to
the east over of the western and central U.S., and northern Mexico. An
area of moderate to heavy density smoke covered most of central and
southern California.

Eastern U.S. and Canada/Atlantic...
A detached plume left over from the western U.S. wildfires was detected
over the Northeastern U.S. and extended over parts of the northwestern
Atlantic, Nova Scotia, and Newfoundland. The plume was of thin density
except for two large moderate density pockets eastern Canada.

Unfortunately, cloud cover over much of the Lower 48 and Canada precluded
further smoke analysis this morning.

DUST:
Atlantic...
A thin plume of Saharan dust was detected on the edge of the eastern
Caribbean Sea.

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.
