DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0000Z June 20, 2025
SMOKE: Alaska/Canada/Northern US... Wildfire activity continues to be analyzed from northeastern British Columbia to western Ontario, with an increase in wildfire activity across Alaska and the Northwest Territory as well. Smoke from these two areas of wildfire activity extend from Alaska and, perhaps, eastern Siberia to parts of the northern Atlantic. Smoke is generally moving eastward from central Canada into northern Quebec, from where the smoke is then drawn northward over the Canadian Archipelago. Some smoke is also observed moving westward from north of Iceland to Greenland. Smoke from the activity across northeastern British Columbia is also seen moving westward toward Alaska and the Gulf of Alaska. Smoke across Alaska is slowly moving with a general general northward movement observed, especially for well-developed smoke plumes. Active smoke plumes across much of the Northwest Territory and northern Alberta and Saskatchewan were moving southeastward to east-southeastward, while the active smoke plumes across Manitoba and western Ontario was moving east-northeastward to northeastward. Northern Mexico/Rocky Mountain States... Multiple fires from northern Sonora to Wyoming were observed producing moderate to thick smoke this afternoon and evening. The moderate to thick smoke was moving west-northwest from a fire in northern Sonora, north from a fire in southwest New Mexico, and north-northwest to northwest from fires in northern Baja California, southern Utah, and western Wyoming. DUST: Mojave Desert… A couple sandy areas of the Mojave Desert in northwest Arizona, southwestern Nevada, and in Death Valley National Park had sand/dust kicked up this afternoon, with the sand/dust moving north-northeast from Arizona into southwestern Utah, north-northeast from southwestern Nevada, and northwest along the California/Nevada border from Death Valley National Park. Gulf of California… Some small plumes of lofted dust were observed moving eastward from sources along the eastern coast of the Gulf of California. Hosley 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
