DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z April 23, 2015

SMOKE

Contiguous US/Central Canada:
Several agricultural and prescribed burns were observed in Saskatchewan
and Manitoba this evening.  Smoke plumes associated with the fires were
moving to the south.

Three large areas of elevated light to moderate density smoke were
observed throughout Central Canada and much of the Contiguous US in
GOES-13 visible imagery this afternoon/evening. Light density elevated
smoke was seen entering the Pacific Northwest as it moves ahead of a
frontal boundary extending from a low pressure system in the Gulf of
Alaska. A band of moderate density elevated smoke was seen moving through
Baja California, the Gulf of California, and into southwest Arizona.
A wide stream of light density elevated smoke with embedded bands of
moderate density smoke was seen moving along the polar jet axis and moving
around a large low pressure system in Quebec.  The stream of smoke moves
in from the north through the Yukon Territory, Northwest Territories,
northeast Alberta, Saskatchewan, Manitoba, eastern Montana, North Dakota,
Minnesota, South Dakota, Nebraska, Iowa, Kansas, Missouri then turns
eastward into Illinois, Indiana, Kentucky, Ohio, West Virginia, Virginia,
North Carolina and finally moves to the northeast as it exits the
east coast.  All areas of elevated smoke originated from fires in Siberia.

Central Plains:
Numerous agricultural and prescribed burns were observed in eastern
Nebraska, eastern Kansas, and northeastern Oklahoma.  Light density
smoke plumes associated with the fires were moving to the west.

Gulf of Mexico:
Light density remnant smoke and a small area of moderate density smoke
were observed in the southwestern Gulf of Mexico and were moving to
the northwest.  The remnant smoke originated from agricultural burns
in Central America and oil exploration in the Bay of Campeche.  A small
area of moderate density smoke from agricultural burns was seen moving
off the Yucatan Peninsula coastline this evening into the Bay of Campeche.

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.
