DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z October 28, 2024
Corrected to add blowing dust along the Canada-US border... SMOKE: Southeastern U.S./Lower Mississippi Valley/Atlantic Ocean... A layer of light to moderate density remnant smoke attributed to seasonal agricultural burning throughout the Mississippi Valley, western Gulf Coast, and southeastern United States was observed over southeastern U.S, Great Plains, and the Gulf Coast before extending southward into the Bay of Campeche then westward across Mexico and into the Tropical Eastern Pacific. There was also extension of this layer eastward across the Carolinas and off the coast out into the Atlantic. The thickest smoke was seen over the Bay of Campeche; the Mexican states of Tlaxcala, State of Mexico, and Michoacan; and the Tropical Eastern Pacific. Some of the smoke may include aerosols industrial activity near Mexico City and emissions from gas flaring in the Bay of Campeche. Mississippi Valley… Widespread smoke production from agricultural burning was observe across much of the central and northern Mississippi Valley today. The smoke was observed moving west-northwestward across northern Arkansas and southern Missouri. Southern Prairie Provinces/Northern Great Plains… Although scattered to widespread agricultural burning was detected, no smoke was detected due to widespread cloud cover over the region. Given the cloud cover and density of fire detections, it is likely that at least some smoke was present this afternoon and evening across this region. AEROSOL: Pacific Ocean/Extreme southwestern California/West Coast of Baja California... A light density aerosol plume was observed over the Pacific Ocean off the California and Baja California Norte coasts. The aerosol was observed moving southward. The source and composition of this aerosol is unknown. BLOWING DUST: Great Basin/Columbia Plateau/Snake River Basin… Sporadic plumes of blowing dust were observed across northern Nevada into southern Idaho this afternoon and evening. The dust was moving northeastward from the point sources. Northern Montana/southeastern Alberta/Southwestern Saskatchewan… Blowing dust was also observed across the Canada-US border being kicked up over a fairly broad region and moving eastward. There is also a single source in Montana that was also producing a longer-lasting plume also moving eastward just behind the larger-scale feature. 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.
