THROUGH 1420Z July 19, 2025
SMOKE: Alaska/Canada/North-Central United States/Atlantic Ocean... Wildfires continued to burn in eastern Alaska/Yukon, and central Canada, with widespread smoke observed across Alaska, most of Canada and extending east towards the Atlantic, north into the Arctic, and south over the Great Plains and towards parts of western Texas and northern Mexico. Higher density smoke plumes are concentrated in much of central Canada, specifically located in northern Alberta, Saskatchewan, and extending as far east as eastern Ontario. Western U.S... Wildfires were observed across the western U.S. with denser plumes generating an area of thicker smoke over northern California, traveling northeastward across northern Nevada and southern Idaho as it merges with smoke from the Canadian fires, and continued toward the Atlantic. Libby 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
