DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0030Z July 5, 2021
SMOKE:
Canada/Alaska/eastern half of the CONUS/Atlantic Ocean...
Wildfire activity continues across central-eastern Alaska, southern
British Columbia, eastern Manitoba, and western Ontario, releasing
thick smoke plumes across the region and further impacting vast areas
downstream. As a result, most of Alaska and Canada (with the exception
of Nunavut), and the eastern half of the Contiguous United States
are under the influence of a very large smoke plume, which is seen
extending further to the east across the northwestern Atlantic. Pockets
of moderate-to-heavy density smoke are found over central-eastern Alaska
and central Yukon, southern British Columbia, southwestern Alberta,
and Ontario, in addition to the upper U.S. Midwest and areas just west
of the Appalachian mountains. The majority of the smoke is dispersing
eastward following the high-level atmospheric flow.
Northern California...
Wildfires in Shasta and Siskiyou counties are emitting heavy density
smoke, which is dispersing toward the northeast over south-southeastern
Oregon and into central Idaho.
Southern Gulf of Mexico...
A stagnant light density smoke plume is seen over the southern Gulf
of Mexico and the states of Veracruz and Tabasco. Smoke is also seen
originating from oil rigs in the Bay of Campeche, and dispersing towards
the north.

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
