DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0100Z April 11, 2021
SMOKE: Central U.S… Numerous seasonal fires in the Central U.S. were responsible for many individual smoke plumes of thin to moderate density which moved generally to the east and southeast with a number of them merging to form larger patches of smoke especially over Nebraska, Kansas, and northeastern Oklahoma. South Central U.S./Mexico/Central America/Gulf of Mexico/Bay of Campeche/Pacific south of Mexico… The ongoing significant amount of seasonal fires occurring in Mexico and Central America were responsible for a huge area of thin to moderate density smoke covering portions of southern and eastern Mexico and Central America and extending to the north over the Bay of Campeche, the western Gulf of Mexico, and south of Mexico over the Pacific. A few embedded patches of thick density smoke were visible closer to some of the more intense fires in Mexico. Thinner density smoke appeared to extend at least as far to the north as southern Texas, southern Louisiana, southern Mississippi, and southern Alabama. It is possible that the smoke may extend even farther to the north over the South Central U.S. though it is not known if the very thin density aerosol seen there was smoke or from some other source. DUST: Western and Northwestern U.S… A fairly significant blowing dust event was underway with dust seen emanating from many sources across a broad region. Rather thick streaks of blowing dust were visible spreading quickly to the east and southeast from sources in the southern and southeastern part of Oregon, southwestern Idaho, and northwestern Utah. Slightly farther to the north, additional plumes of dust over east central Oregon and west central Idaho were seen moving due south. Farther to the east, thick swaths of blowing dust from sources in southeastern Idaho moved to the northeast into southwestern Montana and northwestern Wyoming. The result of all of this was dust of some density basically covered much of the southeastern quarter of Oregon, the southern half of Idaho, and northern Utah. Thinner density dust was just beginning to be seen moving to the east from sources in northeastern California and northwestern and west central Nevada which will likely become thicker as the stronger winds move into this region. 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
