DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 9, 2025
SMOKE: Western Canada/Pacific Northwest... Wildfires persisted throughout western Canada and the northwestern United States. Localized heavy density smoke was seen in west-central Saskatchewan and southern British Columbia. Moderate smoke was observed this evening moving east from British Columbia and south from the Northwest Territories into Alberta, western Saskatchewan, and Northwestern United States. Lighter density smoke extends further out into southern Saskatchewan, southern Manitoba, Ontario, and the Midwestern United States, continuing eastward into the Northeastern United States, Quebec, and Newfoundland. Additional light smoke from previous day agricultural burning across the Mississippi Valley and Southeastern United States was seen merging with the light smoke from the Canadian wildfires. California… The Garnet fire in California remained active this evening. This fire produced a light-to-moderate density smoke plume which was seen dispersing north towards Nevada. The lighter density smoke continued to travel north until it merged with the smoke drifting east from the Canadian wildfires. DUST: Caribbean… Light dust from the Sahara Desert was observed moving west towards the Lesser Antilles. Libby 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:http://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
