DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0310z September 30, 2020

SMOKE:
West Coast/Great Basin/Northwestern Mexico...
Major wildfires throughout central and northern California continue to
produce heavy smoke.  Moderate and heavy density smoke is observed over
central California and covers most of northern California extending west
offshore for over 400 miles into the Pacific Ocean.  An area of light
density smoke covers all of California, southwest Arizona, western and
northern Nevada, southern Idaho, most of Washington, western Oregon and
northwestern Mexico.  The light density smoke extends approximately 700
miles off the coast over the open waters of the Pacific.

Utah...
A wildfire complex in the northeast part of the state is spreading a
light to moderate density plume to the south.

Wyoming/Colorado..
A couple of wildfire clusters near the state border are spreading
a large light density plume that is moving to the east-southeast.
Moderate to heavy density plumes are found within this light density
plume also spreading to the east-southeast.

Atlantic...
A large area of light density smoke is visible off the East Coast
stretching about 1700 miles out from Newfoundland.  A large area of
moderate density smoke is observed starting about 480 miles off the
coast of Newfoundland extending 1200 miles east over the open
Atlantic.


DUST:
Atlantic...
A large thin plume of Saharan dust covers most of the central and
eastern subtropical and tropical Atlantic.  The plume is moving
westward.

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.
