DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1740Z July 20, 2021

SMOKE:
Alaska/Canada/U.S....
Ongoing wildfires with the largest and most intense areas over eastern
Alaska/the Yukon, southeastern British Columbia/Pacific Northwest, and
far southwestern Ontario/southeastern Manitoba continue to support a huge
light density plume that covers eastern Alaska, most of central and
southern Canada, and a significant portion of the Continental U.S.  A
large area of moderate density smoke is found over eastern Alaska,
northern Yukon, and the northern part of the Northwest Territories.  A
second large area of moderate density smoke was detected over most of
the Pacific Northwest/southern Canada and the area extending from the
Northern Plains and Front Range all the way to the Mid-Atlantic and
Northeast.  Heavy density smoke plumes were found over southeastern
British Columbia, parts of the Pacific Northwest, the central part of
Manitoba, far southwestern Ontario, and from the Ohio Valley to western
New England.


DUST:
Caribbean/Atlantic...
A light plume of Saharan dust was detected across the central and
eastern Caribbean and extended several hundred miles north or Puerto
Rico and Hispaniola.

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.
