DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1900Z September 18, 2022
SMOKE: Northwestern U.S./Southwestern, Central and Northern Canada... A large area of remnant light smoke from California wildfires and other wildfires across the western U.S. and western Canada covered the northern most part of the northwestern U.S., the Dakotas, Minnesota and Iowa, and the southwestern and central Canada. Another area of light smoke could also be seen stretching across northern Canada from the eastern Northwestern Territories, to northern Hudson Bay and northern Quebec. Pockets of medium density smoke were present over northwestern Washington, the Dakotas, Minnesota, and western-southern Manitoba. Eastern United States... Light smoke was visible covering a large expanse including the Midwestern U.S., the Mississippi Valley and areas to the east with the exception of central-southern Florida. Multiple agricultural fires contributed medium density smoke along the mid-Mississippi Valley, while a larger area of medium density remnant smoke extended from the Florida Panhandle, to areas east of the Appalachian mountains all the way to Cape Code, and further to the east off the Mid-Atlantic coastline for approximately 500 miles. WS 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 map: https://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
