DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z July 14, 2021

SMOKE:
Alaska/Canada/Northern CONUS/Greenland/North Atlantic…
An expansive layer of varying density smoke blankets much of northern
North America from Alaska to Greenland and Newfoundland. Smoke from
Siberian wildfire activity is to blame for smoke thin to moderate smoke
moving from the eastern end of Russia across the Bering Strait across
central Alaska and into the Yukon Territory. Wildfire activity across
British Columbia and the Pacific Northwest continues to produce thick
smoke, which is moving across western Canada into northern Canada. From
there, the smoke reaches Baffin Island before being dragged southwestward
into northern Saskatchewan and Alberta, where persistent wildfire
activity is also producing thick smoke and adds to the remnant smoke
layer. From this activity, the smoke advects over the Great Lakes, where
some spreads south and southwest across the Ohio and Mississippi Valleys
as well as across the Great Plains. A small area of light remnant smoke
from previous days was observed over the Desert Southwest as well. The
main stream then continues across Ontario and into Quebec, rounding the
large upper-level trough over Hudson Bay and then the upper-level ridge
over southern Quebec. The smoke then moves over Greenland and Newfoundland
and converges near a frontal system across the North Atlantic.


DUST:
Central America/Yucatan Peninsula/Caribbean and Sargasso Seas…
Light to moderate Saharan Dust was observed in a layer extending from
the Eastern Caribbean Sea to just off the North Carolina coast. The
thickest dust was seen over Hispaniola, Cuba, Jamaica, the Bahamas, and
southeastern Florida. The layer extends eastward into Central America and
the Yucatan Peninsula as well, possibly into the eastern Bay of Campeche.

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.
