Central Canada/North Central US:
Detatched smoke originating from the fires burning across Alaska was
visible this evening stretching southwestward from Hudson Bay across
Ontario and Manitoba Provinces to near the border of northwestern
Minnesota. The smoke has been entrained into the large cyclonic vortex
located just south of Hudson Bay.

Active fires were still burning over eastern Alaska with some smoke
visible mainly across Yukon-Koyukuk County. However, extensive cloudiness
is preventing the detection of additional areas of smoke which are likely
still present.

Western US:
A very large area of moderately dense smoke and blowing dust was seen
this evening stretching from west central Nevada northeastward to the
Canadian Provinces of Alberta and Saskachewan. Large fires producing
significant smoke plumes fanned by gusty southwesterly winds and low
dewpoints were observed especially across central and northern Nevada,
southern and central Idaho, and western Montana. Mixing with this area of
smoke were clouds of blowing dust originating from dry lake beds/open
vegetation free areas of west central and northwestern Nevada and
northeastern California. Especially prominent were dust clouds coming
from Churchill, Pershing, and Humboldt Counties of Nevada and Lassen
County of California. Other plumes of blowing dust could be seen moving
southeastward across south central and southwestern Idaho. Yet another
area of blowing dust originating from Laguna Salada in far northwestern
Baja was spreading northeastward all the way into south central Arizona,
just southwest of the Phoenix vicinity. Finally, a fire burning across
central San Bernardino county of southern California was producing a
smoke plume which has spread as far east as Las Vegas, NV.



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.
