DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0245Z August 4, 2015

SMOKE
West Coast/Pacific Northwest/Southwest Canada/Central US:
A very large mass of smoke of varying density was visible moving to
the north and northeast across northern California, much of Oregon and
Washington, northern Idaho, and into the southern portions of British
Columbia, Alberta, and Saskatchewan in southwestern Canada. From there,
the smoke spread to the southeast across Montana and over the Northern and
Central Plains to at least as far east as the Ohio Valley. The thickest
smoke was present closer to the largest and most active wildfires over
northern California, western Oregon, as well as western and northern
Washington, and far southwestern Canada. However, some of at least
moderate density was detected from southern Alberta and southern
Saskatchewan across Montana to the Central Plains.

Alaska:
Several fires over central Alaska were emitting primarily thin to
moderately dense smoke plumes which spread to the east during the
day. Dense smoke was confined to very near the actual fires.

Northwestern Canada:
Fires between Great Bear and Great Slave Lakes in northwestern Canada
were responsible for patches of moderately dense to thick smoke which
moved mainly to the west and north during the day.

Gulf of Mexico:
Smoke from platforms in the Bay of Campeche was detected moving to the
west and northwest during the late afternoon and evening.

DUST
Gulf of Mexico/South Texas:
Some patches of what is believed to be Saharan dust was visible prior to
sunset over portions of the Caribbean westward across the Gulf of Mexico
and into far southern Texas and northern Mexico. Some of the Saharan dust
seen earlier this morning was still visible off the Southeast and Middle
Atlantic U.S. coast, though it was being obscured by frontal cloudiness
in this region.

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:

ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO

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.
