DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0230Z July 25, 2020

SMOKE:
Western U.S…
A number of wildfires in northeastern California were emitting moderately
dense to very thick smoke which spread to the east during the day with the
thickest smoke covering northeastern California, a portion of far southern
Oregon and northwestern Nevada. Thin to moderately dense smoke affected
more of southern and eastern Oregon, northern Nevada, the southern half
of Idaho, northwestern Utah, northwestern Wyoming, southwestern and
central Montana, and even as far north as southern Saskatchewan province
in Canada. Farther to the north, wildfires in central and northeastern
Washington were producing locally thick smoke which gradually thinned out
as it spread to the east. Smoke from the Greenhouse Fire in northeastern
Washington moved across northern Idaho into northwestern Montana.

DUST:
A very large mass of Saharan dust extends from the west African coast
across the tropical Atlantic with the leading edge appearing to spread
over Puerto Rico and most of the islands to its east and southeast.

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.
