DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0130Z October 20, 2017

SMOKE:
California...
Wildfires along the Sierra Nevada were seen producing thin to moderate
density smoke plumes. The most intense smoke plume was associated with
a fire in Yosemite National Park. Most of the smoke emitted from these
fires was being blown off to the northeast. In northern California,
smoke was likely being emitted from the persistent wildfires along the
coastal range of northern California. However, cloud cover associated
with a frontal system limited the analysis of smoke in this region. Even
with the cloud cover impinging on the region, precipitation had not
begun in the vicinity of the fires through the end of the analysis. Also
of note...in the southern San Joaquin Valley, a feature was seen that
could be remnant smoke trapped within the valley. This could also be
photochemical haze or even a little dust.

Texas Gulf Coast...
A wildfire in McFaddin National Wildlife Refuge continued to burn today,
although not as intense as yesterday. Thin density smoke was produced
and covered southeastern Texas. The exact extent of the smoke plume was
obscured by cloud cover.

Southeastern CONUS...
Agricultural burns throughout the southeastern US were observed producing
light to moderate density smoke plumes. The observed smoke plumes were
seen mainly in Alabama, Georgia, the Florida panhandle, and the northern
portions of the Lower Mississippi River Basin. There were likely smoke
emissions from fires throughout southeastern Arkansas and Louisiana,
but cirrus cloud cover was obfuscating any of those emissions.

South-central Canada/Northern Plains...
A dozen or so agricultural burns across the Northern Great Plains were
seen producing light to moderate density smoke. This smoke was seen being
blown off to the northeast. Again, cloud cover interfered with analysis
of smoke across south-central Saskatchewan to the southern shores of
Lake Winnipegosis.


DUST:
Tropical North Atlantic...
Saharan dust was seen across much of the North Atlantic extending from
Hispaniola and the southeastern Bahamas to southeast of Bermuda and
across the Lesser Antilles into the open tropical north Atlantic Ocean.

Central Nevada...
Blowing dust was observed emanating from a dry lake bed in Lander County
just west of Iron Mountain. This dust was seen moving to the northeast
as it dispersed.

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.
