THRU 0300Z JULY 19, 2005

Alaska/Northwestern Canada:
Abundant cloudiness covers a good portion of Alaska today making fire and
smoke detection difficult. A widespread batch of intense fires burning
across northwestern Canada between Great Bear Lake and Great Slave
Lake is producing significant smoke which has been observed spreading
southward during the afternoon and evening.

Southeastern Canada:
Very large fires scattered across Quebec Province and Newfoundland
Province are responsible for an enormous swath of smoke covering
southeastern Canada and extending well off the coast of southeastern
Canada and over the Atlantic Ocean. The majority of the smoke plumes
were moving off to the northeast early this evening.

Southwestern US:
Large wildfires burning across several western states are producing
a significant area of smoke covering a good portion of the area from
southern Idaho to southeastern California and southern Arizona. Visible
imagery showed the fires over northern Nevada as well as ones over
northern and central Arizona were emitting very thick smoke plumes. Some
of these fires appeared to be quite convective in nature with enhanced
bursts of smoke emanating from them early this evening. In addition to
the smoke, visible imagery also indicated at least one area of possible
blowing dust across northern Utah moving eastward into southern Wyoming.


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.
