DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2350Z July 3, 2025
SMOKE: Alaska/Yukon/Canada… Widespread wildfire activity continued across central Yukon, eastern British Columbia, southwestern Northwest Territories, Alberta, and Saskatchewan, producing a vast area of light to moderate smoke that stretched from northern and western Alaska eastward across central Canada and into western Quebec. The most concentrated smoke, approaching moderate to locally heavy densities, was centered over northern Alberta and northern Saskatchewan, linked directly to clusters of persistent large wildfires. The smoke generally moved east and southeast across the Canadian Prairies and into Ontario, while light smoke wrapped northwest across Yukon and back into portions of Alaska. Central and Eastern United States… Diffuse light smoke extended into the northern Plains and Midwest, with scattered patches reaching the Ohio Valley. This was primarily from long-range transport of Canadian smoke, combined with contributions from localized burning in parts of the central U.S. Pacific Northwest… Fires from northern California into Washington State were observed producing light to moderate smoke. Smoke was moving southwest from fires in northern California and east-southeast from fires in the Washington Cascades and north-northeast from a fire in eastern Washington. Southern California and the near-shore Pacific… The Madre fire along the southern rim of the Central Valley is producing thick smoke that is observed extending south and south-southeastward over the Channel Islands, perhaps with some light to moderate smoke encroaching on the Los Angeles to San Diego Metro area. Cardona 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
