DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1600Z September 29, 2022
SMOKE: Central CONUS/south-central Canada… A sizable area of mainly light remnant smoke was seen blanketing an area from the southern Gulf of Mexico and the Great Plains northward into the Prairie Provinces. One source of the remnant smoke across the southern Gulf of Mexico and the southern Plains was the agricultural burning over prior days across the Mississippi Valley and southeastern CONUS. The smoke across the southern Gulf of Mexico was drawn south in the wake of a frontal passage, while smoke across Texas, Oklahoma, and Kansas was drawn westward by the high pressure that built in behind the frontal passage. Further north, remnant smoke, possibly still from agricultural burning across the Mississippi valley but more likely from wildfire activity across the Pacific Northwest over the past few days, was observed. The more lofted remnant smoke over the Prairie Provinces extending just into Ontario and Hudson Bay was moving west while smoke over the central and northern Plains was remaining fairly stagnant. Mississippi Valley… Seasonal agricultural burning had begun for the day from southwestern Missouri southward into central Louisiana. The smoke plumes were observed mainly moving west-southwest aside from the smoke across Louisiana, which was seen moving southward. Northwestern Canada… Wildfire activity was observed in the far southwestern portion of the Northwest Territory. Active moderate density emissions were seen around the parent fire activity drifting mainly toward the east and north, while mainly light remnant smoke was seen extending northward. A remnant plume of moderate density smoke was also seen moving north across central Northwest Territory. Elsewhere… Wildfire activity continues to be detected across the Pacific Northwest. However, due to extensive cloud cover across Washington State, northern Idaho, and western Montana, smoke could not be conclusively analyzed across this region. Even though smoke is not analyzed, it is likely that at least some light to moderate smoke is present given the detection of persistent wildfire activity today and the analysis of smoke from this fire activity yesterday. 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 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
