DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z July 11, 2025
SMOKE: Alaska/Canada/North-Central United States/Atlantic Ocean... Wildfires continued to burn across Northwestern Alaska, Northwestern and Central Canada with widespread smoke covering Northern Alaska, large parts of Northwestern and Central Canada, the North-Central United States, and portions North Atlantic Ocean. Areas of higher smoke concentration are found moving northeastward along Central Saskatchewan and Manitoba, Western Ontario and over the Hudson Bay. California/Nevada/Utah/Arizona/Colorado... The large Mount Irish Fire in southern Nevada remained active this morning with smoke being dispersed towards the east into Utah. Several other large wildfires in southwestern Utah, north-central Arizona, and west-central Colorado were also observed producing locally moderate to heavy density smoke drafting northeast. Lighter density smoke was extending further and merging with smoke from the Canadian fires. Additional wildfires in Northern California were also seen producing moderate to heavy smoke near the sources with a lighter density plume extending south and east. Rodriguez 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
