DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z July 25, 2025
SMOKE: Central Canada... Wildfires continued to burn in the Northwest Territories, Alberta, Saskatchewan, and Manitoba, and generated a large area of light smoke which covered most of the northern continent from Alaska to the Atlantic. Large plumes and thicker density smoke concentrated in the southern Northwest Territories, Saskatchewan, Manitoba, and drifted east over Ontario, southern Quebec, and Newfoundland. Western United States... Fires in eastern Washington, northwestern Oregon, central Idaho and northern California produced moderate density plumes which drifted northeast. Larger fires in Utah and northern Arizona generated thick smoke which spread to the east into a large area of moderate smoke across Colorado and Wyoming, and merged with the smoke from Canada moving toward the Atlantic and Greenland. Mills 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
