DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z August 22, 2020
SMOKE: Western and Central U.S./Southwestern and South Central Canada/Western Gulf of Mexico/Northern and Central Mexico/Pacific off the Coast of Southern California and Baja… The enormous mass of smoke attributed mainly to a number of large wildfires burning in northern and central California along with some contribution from other wildfires scattered across the Western U.S. continued to be visible covering virtually all of the Western and Central U.S. and nosing up across southwestern and south central Canada and eastward over the western Great Lakes region. The smoke also extended southward over northern and central Mexico along with the western Gulf of Mexico and the Bay of Campeche where it merged with smoke spreading west from the oil rigs in the Bay of Campeche. Smoke also extended very far to the west and southwest off the coast of southern California and Baja over the Pacific. Similar to yesterday, the only relatively smoke free areas of the west were far northwestern California, western Oregon, and western Washington where onshore flow again kept the smoke farther to the east. Also similar to yesterday, embedded within this large mass of smoke was an unusually large area of dense smoke which stretched from southeastern Washington, central and eastern Oregon, and much of California eastward over the Rockies to the Plains from the western Dakotas southward to western Oklahoma and northwestern Texas. While the most concentrated fire activity producing the thickest smoke was located in northern and central California, virtually every Western state had at least some wildfire activity producing individual dense smoke plumes. DUST: Caribbean Region/Subtropical Atlantic… Saharan dust was visible extending from the coast of Africa westward over the eastern and central subtropical Atlantic. From there, the dust curved in a more narrow band to the northwest and eventually to the southwest around the periphery of Tropical Storm Laura. The portion of the band to the west of Tropical Storm Laura appeared to be moving west of Puerto Rico and now passing over Hispaniola. JS 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: http://www.ospo.noaa.gov/data/land/fire/currenthms.jpg GIS: ftp://satpsanone.nesdis.noaa.gov/FIRE/HMS/GIS/ KML: http://www.ospo.noaa.gov/data/land/fire/fire.kml (fire) http://www.ospo.noaa.gov/data/land/fire/smoke.kml (smoke) ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO: SSDFireTeam@noaa.gov
