DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z August 31, 2016

SMOKE:
Far Western US/Southwestern Canada:
Moderately dense to locally thick smoke from a new fire well east of Los
Angeles spread to the west and over portions of the Los Angeles metro
area late in the day. Farther to the north, fires near the coast of
south central California were still producing moderate to dense smoke
which fanned out to the southwest and offshore and inland toward the
central Sierras. Over far northern California, a large wildfire was
emitting a large very dense smoke plume which moved mainly to the north
into southwestern Oregon. Thin to moderately dense smoke from this fire
also extended northward over portions of central and northern Oregon
and Washington and into southern and southeastern British Columbia
and Alberta in Canada. Also, a large mass of mainly thin density smoke
attributed mainly to the fires near the coast of south central California
stretched to the east and northeast over a good portion of central and
southern California, much of Nevada, and into Idaho.

Area from Idaho to the North Central US/South Central Canada:
Numerous wildfires over Idaho, western and southwestern Montana, and
northwestern Wyoming were responsible for a large area of moderately
dense to thick smoke which covered the region from central Montana to
the Dakotas. Locally dense smoke was also briefly visible in between
breaks in the clouds closer to the actual fires though cloudiness did
significantly interfere with smoke information in those locations. In
addition, a stripe of moderately dense smoke from these fires fanned
out to the south reaching into north central Colorado. Farther to the
north, thin to moderately dense smoke from the large fire in far northern
California rounded the top of an upper level ridge and began moving to
the southeast from Alberta across southern Saskatchewan and southern
Manitoba and over the US border into northern Minnesota.

Earlier This Morning...
DUST:
Alaska:
An aerosol seen in the Gulf of Alaska drifting westward towards Kodiak
Island may be airborne glacial flour which was visible yesterday evening
moving offshore from a source in the far northern panhandle region of
southeastern Alaska.

Caribbean/Tropical Atlantic:
African dust stretches from the Leeward Islands west across the Caribbean
Sea to Jamaica. Optically thick dust is also seen across the Atlantic
waters north of Puerto Rico and Hispanola.

UNKNOWN AEROSOL:
Mid-Atlantic Coast/Western Atlantic:
An area of aerosol can be seen this morning to the north of a stationary
boundary that is draped from the Virginia/North Carolina border eastward
across the western Atlantic. The aerosol extends as far north as southern
New Jersey and can be seen from the Chesapeake Bay Region east over the
open ocean. Aerosol models indicate quite a mixture in this area with
remnant smoke, light dust, and sulfates all present off the Mid-Atlantic
causing the hazy conditions seen in satellite imagery.

Southern and Central Plains to Midwest:
Unknown aerosol covers much of northern and eastern Texas this morning
as well as northwest Louisiana/western Arkansas stretching north across
Oklahoma, southeast Kansas, Missouri, Illinois, and northern Indiana
where it then becomes cloud covered. Some remnant smoke from agricultural
burning in the Central Plains yesterday may be present but the majority
of the aerosol is thought to be sulfates and haze.

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.
