DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z May 13, 2016

SMOKE:
Earlier This Morning...
Patches of leftover thin density smoke from fires in northern California,
Oregon, and Washington were visible this morning drifting eastward over
eastern Washington and into northern Idaho and western Montana as well
as from southeastern Oregon into southern Idaho.

During the Day...
Pacific Northwest:
Fires were once again detected scattered across northern California,
Oregon, and Washington with a few smoke plumes seen though cloudiness
passing over the region interfered with additional information concerning
smoke extent and density.

Western and Southern Canada/North Central and Central US:
The ongoing fire near Ft. McMurray in eastern Alberta was producing thick
smoke which moved southward during the day over central and south central
Alberta. Satellite imagery also showed a large area of thin to moderately
dense smoke associated primarily with this fire extending to the south
and southeast over south central Canada and over the border into portions
of Montana, North Dakota, and Minnesota. The smoke stretched southeast
from there across the Central Plains reaching nearly to St. Louis,
Missouri just prior to sunset.

Southeastern Canada/Northeastern US:
Leftover thin to moderately dense smoke from some of the recent wildfire
activity in south central and western Canada was still visible during
the day stretching from Quebec Province across much of the Northeastern
US and offshore over the Atlantic.

Bay of Campeche/Western Gulf of Mexico/Southern Texas/Southwestern
Louisiana:
Thin to moderately dense smoke from the ongoing seasonal burning was
detected over the Bay of Campeche and the western Gulf of Mexico. Thinner
smoke also likely extended farther to the north into southern Texas and
southwestern Louisiana though there is some uncertainty as to how much
of the aerosol seen there is composed of smoke.

Western Alaska/Bering Sea:
Thin density smoke attributed to wildfire activity in Siberia has
become entrained in a weather system and transported over the Pacific
and northward over a portion of the Aleutian Islands and southwestern
Alaska. Cloudiness in this area interfered with additional information
on the smoke extent and density. Farther to the west, smoke from the
Siberian fires was also seen over a portion of the Bering Sea.

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.
