DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z September 7, 2026
SMOKE: Canada… Despite significant cloud cover, wildfires in the southern Northwest Territories continued to burn this morning, which produced a localized area of medium-to-heavy density smoke that drifted south. A layer of remnant medium-to-heavy density smoke was observed extending eastward from Nunavut across the Hudson Bay and northern Quebec, eventually reaching the Davis Strait. A broader layer of light-density smoke was observed over much of northern Canada, extending southeastward from the Northwest Territories into northern British Columbia, Alberta, Saskatchewan, Manitoba, and Ontario before drifting eastward across Nunavut towards Greenland. CONUS… A layer of remnant light density smoke was observed drifting southward across the Central Plains before extending eastward into the Southeastern U.S. and southwestward into Mexico. California… The Plaskett Fire in Monterey County, California was observed producing light density smoke drifting southeastward along the coastline before moving west over the Pacific Ocean. Mexico… A small layer of light-density smoke from fires, industrial activity, and smoke from CONUS was observed over northeastern Mexico. A separate layer of light-density smoke was observed over the Isthmus of Tehuantepec, extending northwestward along the Mexican Pacific Coast and southeastward into Central America before dispersing southwestward into the Pacific Ocean. GL 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: JPEG map: https://www.ospo.noaa.gov/data/land/fire/currenthms.jpg Smoke data: https://satepsanone.nesdis.noaa.gov/pub/FIRE/web/HMS/Smoke_Polygons Fire data: https://satepsanone.nesdis.noaa.gov/pub/FIRE/web/HMS/Fire_Points ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO: SSDFireTeam@noaa.gov
