DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z July 27, 2025
SMOKE: Alaska/Canada/Northeast United States/Atlantic Ocean... A large area of light density smoke persisted over the northern continent from ongoing wildfires in northeastern Alaska, and northwestern and central Canada. Fires in Saskatchewan produced the largest plumes and thickest density smoke which spread east over Manitoba and Ontario. Moderate density smoke continued into the Atlantic with light smoke reaching Greenland and circulating north into the Arctic. Arizona/Utah/Wyoming... Fires continued to burn in Utah, northern Arizona, and Wyoming which produced a widespread area of moderate-to-light smoke that drifted northeast across the Dakotas and merged with the smoke from Canada. Lighter smoke spread mainly east with some drifting back south along the Atlantic coast. California… The Orleans Complex fire in northern California continued to produce moderate-to-light density smoke which spread to the northeast. 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
