DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0000Z June 5, 2026

SMOKE:
Central Canada/Northern Plains…
Wildfire activity from northern Alberta and southern Northwest Territory
to northern Manitoba was producing moderate to thick smoke. The smoke
from this activity was moving northeastward from the Manitoba fires,
northwest to northeast from northern Alberta and Saskatchewan, and
eastward to east-northeastward from southern Northwest Territory. In
addition to active smoke emissions, remnant smoke was forming a layer
of smoke across southern Northwest Territory extending eastward over
Nunavut. Another area of remnant smoke, likely also supplied by this
wildfire activity coupled with other fire activity across North Dakota,
Minnesota, and southern Manitoba, was also noted across much of Alberta,
Saskatchewan, Manitoba, the Dakotas, Minnesota and far northwestern
Ontario. A third area was also analyzed across Quebec and the Maritime
Provinces. It may very well be true that these three areas may comprise of
one sprawling area of smoke; however, cloud cover was making it difficult
to conclusively connect these areas of smoke.

Mid-Atlantic/Southeastern CONUS…
Scattered to widespread fire activity was analyzed from Virginia to
Mississippi, with much of the smoke production observed across the
Atlantic and Gulf Coastal Plains. Smoke was moving clockwise around a high
pressure area over the Appalachians, with the only exception in southern
North Carolina in the afternoon with a presumed sea breeze moving smoke
northwestward in the mid-to-late afternoon. Most smoke was relatively
light in nature with one or two producing notably more dense smoke.

Pacific Northwest…
A fire in Washington State’s Yakima Valley and another fire in Boise
National Forest were both producing light to moderate smoke today. The
smoke from these fires was moving eastward.


SMOKE/AEROSOL:
Mexico/Pacific Ocean/Gulf of America...
Fire activity, aerosol emissions from gas flaring and other industrial
activities, and remnant smoke from previous days contributed to a
widespread layer of light-density smoke and aerosols across south and
central Mexico. The smoke extended southwest into the Pacific Ocean, and
north across the western Gulf of America, ultimately reaching southern
Texas. A large area of moderate-density smoke was observed in the southern
Gulf of America drifting southward across Mexico and the Isthmus of
Tehuantepec into the Pacific Ocean. Additional area of moderate-density
smoke was observed on the Pacific coast of southern Mexico.

BLOWING DUST:
Tropical Atlantic/Caribbean/Yucatan/Bay of Campeche…
Saharan Dust was observed spanning the entire Atlantic as far west as
the Bay of Campeche, and from Central America northward to the southern
Gulf of America. It is possible that some Saharan Dust is also seen a
little farther north moving into southern Texas and possibly over Mexico.

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

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.
