DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z September 21, 2022
SMOKE: Eastern, Central and Northwestern United States, Southern Canada…. Ongoing wildfire activity across the Pacific Northwest and southwestern British Columbia was observed producing moderate to thick density smoke. From the parent fires, the smoke is moving west across Idaho, Washington State, northern Oregon, southwestern British Columbia, and the Pacific Ocean. The most dense smoke was produced from 2 fires in central Victoria Island, northern Idaho, and the Cascades of Washington. Some of the smoke from these fires from the past few days has become incorporated into a low pressure system off the California coast, allowing the smoke to move over northern and central California as well. Some of this smoke may also have been drawn northward across northern Canada, but this could also be transport from across the Arctic or Pacific. A small portion of the Pacific Northwest smoke was also moving eastward. The smoke then makes its way into Ontario. From there, the smoke moves across the Mid Atlantic and out across the Atlantic Ocean. A small portion of that smoke also may be present across the southeastern CONUS. Mid-Mississippi Valley… From southern Illinois into the ArkLaMiss, widespread light to moderate smoke plumes of agricultural origin were observed. The movement of these smoke plumes was governed by a high pressure area at the surface centered over the middle of the Arkansas/Mississippi border. Remnant smoke from activity in this area could be responsible for a moderate area of smoke over the northwestern Gulf of Mexico. 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
