DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z September 25, 2026
SMOKE: Canada… Despite significant cloud cover, a layer of remnant light-density smoke was observed extending eastward from the Northwest Territories into the Hudson Bay. Another layer of light-density smoke was observed over southeastern Alberta, extending northeastward across central and southern Saskatchewan into Manitoba. CONUS… Significant cloud cover was present over much of the Pacific Northwest and Midwest, as well as portions of the Atlantic coast. However, layers of remnant light-density smoke was observed across the Southeastern U.S., with some of the smoke moving northeastward through the Mid-Atlantic and then east toward the Atlantic Ocean. Mexico/Pacific Ocean/Gulf of America… Remnant layers of light-density smoke from agricultural burning and industrial activity was observed across northern Mexico along the Mexico-Texas border, with the smoke dispersing locally. Another layer of light-density smoke was observed along the southern coast of Mexico, extending westward offshore into the Pacific Ocean. Hernandez 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.
