DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0115Z October 3, 2025

SMOKE:
Central Canada/Lower Mississippi Valley/Southeastern United States/Gulf
of America...
Despite heavy cloud cover obscuring northern Canada, a large area of
remnant, light-density smoke from the previous day’s activity was still
visible in southern Saskatchewan and southern Manitoba. The smoke moved
east toward northern Ontario and north toward Hudson Bay. Additional
smoke from these fires moved south into the United States, continued
further through the Midwest, merged with smoke plumes from agricultural
fires in the Lower Mississippi Valley and the Southeastern U.S., and
ultimately reached the northern Gulf of America.

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.
