DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z September 22, 2022
SMOKE: Northwestern United States, Pacific Ocean, and western Canada... Wildfire activity across southern BC into Washington State and Idaho was seen producing mainly light to moderate smoke with one or two in the Cascades producing thick smoke. Further smoke production was likely occurring across the area ate in the afternoon, but cloud cover began to obscure the region and hampered the ability to analyze smoke. From the parent activity, most of the smoke was moving west to northwest across northern Idaho, Washington State, and across the Pacific Ocean. Then a portion moved south just offshore of Oregon and California while a portion moved north into western Canada and perhaps eastern Alaska. Mississippi Valley/Southeast/Mid-Atlantic/Gulf of Mexico/Atlantic Ocean… A mix of active and remnant smoke from agricultural burning across mainly the Mississippi Valley was seen this afternoon and evening. An area of light to moderate density smoke from today’s fire activity was seen moving mainly eastward from the Mid-Mississippi Valley and southeast to south from the lower Mississippi Valley. Other very light smoke was seen moving clockwise around a high pressure area centered over southern Arkansas. Further north, some of the smoke from fires in the Missouri Bootheel wee seen moving rapidly eastward across the Ohio Valley. Further remnant smoke from previous days was seen across the southeastern CONUS and the Mid-Atlantic extending eastward across the Atlantic. Much of the smoke was moving eastward from the Mid-Atlantic and south to southwestward across the southeastern CONUS. Curiously, an area of slightly more dense remnant smoke was seen extending eastward from an area of low pressure south of Newfoundland to Tropical Storm Gaston. BLOWING DUST: Nevada… Strong winds out of the south-southwest were seen lofting and blowing dust north-northeastward across central and northeastern Nevada this afternoon. The blowing dust was fairly thin. 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
