DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0315Z July 6, 2013

Alaska/Western Canada:
Cloudiness over Alaska and far western Canada interfered with smoke
detection so only a few patches of smoke were visible mainly over eastern
Alaska and the Yukon of western Canada.

Southwest US:
A large area of primarily light remnant smoke from the fires in the
Southwest over the past few days was visible circulating around an
area of upper level high pressure over the Southwestern US. The smoke
covered southern California, and a portion of Arizona, and extended to the
northeast as far as the central high plains around western Nebraska. The
smoke also stretched to the south over far western Mexico and over the
eastern Pacific off the Mexico and southern California coast. Smoke
coverage may also extend over a greater portion of the Southwest but
cloudiness prevented detection in these areas. Thicker smoke was seen
moving to the east and northeast from the Carpenter 1 fire in southern
Nevada west of Las Vegas. This moderately dense to very thick smoke
reached into southwestern Utah. Another plume of moderately dense to
very thick smoke spread to the northeast over northern Nevada from a
fire to the southeast of Lake Tahoe.

Central US:
An elongated area of very light, elevated remnant smoke mainly from the
fires in Canada was seen stretching from the just north of the Great
Lakes region into east Texas. Moderately dense smoke from the fires in
northern Manitoba and the fires in Quebec was again moving to the south
and had reached northern Minnesota just prior to sunset.

Canada:
Wildfires scattered from the southern part of the Northwest Territories
and northern Alberta to northern Manitoba were emitting various amounts of
smoke which moved in a southerly direction during the day. Over Quebec,
huge fires continued to burn with the majority of the very dense plumes
moving to the east. A very large west to east elongated mass of remnant
thin to moderately dense smoke from all of the Canadian fires stretched
from the southern part of the Northwest Territories and northern Alberta
to off the coast of southeastern Canada. Within this large area, the
thickest smoke was visible stretching from the fires in Quebec to off
the southeastern Canada coast.

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.
