DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1900Z September 18, 2022
SMOKE: Northwestern U.S./Western and Central Canada... A large area of remnant light smoke from California wildfires and other wildfires across the western U.S. and western Canada covered the majority of the northwestern U.S. and the western and central Canada reaching the Hudson Bay. Light smoke continued to cover the northernmost US states, the Great Lakes region, Mississippi Valley, Ohio Valley and all of the eastern US, then extended out into the western and central Atlantic. Heavy cloud cover obscured visibility of the true extent of the smoke over northern California, northern Nevada, the Pacific northwest and northern Canada. It is likely varying degrees of smoke exists in these areas. Eastern United States... Predominantly 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 Florida. Multiple agricultural fires contributed medium density smoke along the southern-Mississippi Valley, while a larger area of medium density remnant smoke covered the Appalachian mountains from the panhandle of Florida northeast to Cape Cod and off the mid-Atlantic coast. JL 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
