DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z Thursday, September 4, 2020
SMOKE:
Western U.S./Pacific...
Intense wildfire activity continues across California. The Red Salmon
Complex, North Complex, Slink, SQF Complex and August Complex fires
were all producing thick smoke contributing to a large area of attached
and remnant smoke. This layer of smoke blanketed the Central Valley,
northern California, southwestern Oregon, the Pacific Ocean offshore of
northern California, Oregon and Washington, and came back ashore across
Victoria Island, the Olympic Peninsula, southwestern British Columbia
and northwestern Washington State. The thickest smoke was being produced
by the SQF and August Fire Complexes, with thick smoke extending between
125 and 150 miles west-northwest from each fire.
Oregon/Washington...
Fires in Oregon (Beachie Creek and Lionshead) and Washington (Evans
Canyon) were observed emitting thick smoke this afternoon and evening. The
smoke from the Lionshead and Evans Canyon fires was moving off toward the
east-southeast, while the smoke from the Beachie Creek fire was moving
west-northwest then north-northwest later in the afternoon. Some remnant
smoke was moving off toward the west-southwest, also contributing to
the region described above.
Northern Rockies/Central Plains/Ohio Valley/southeastern Canada...
Wildfire activity across southeastern Montana, as well as the Cameron
Peak fire in north-central Colorado, is contributing to a large area of
smoke extending southeast across Wyoming, Nebraska, Kansas. The smoke then
moves eastward across Missouri, Illinois, and Indiana. After this, the
smoke moves east-northeast across southern Ontario and southern Quebec.
DUST:
Bermuda Triangle…
What is believed to be Saharan Dust has become entrained in a high
pressure center extending from off the Delmarva Coast south-southwestward
into the Bahamas. The dust over the Bahamas was moving west and the dust
off the Delmarva and Carolina Coasts was moving east-northeastward.

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
