DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1800Z July 7, 2020
SMOKE: Nevada… A wildfire in Nevada, possibly a re-invigoration of the Monarch Fire, was observed producing moderate to thick density smoke this morning. This smoke was infiltrating the valleys east and southeast of the fire. Smoke making it above the valleys was moving mainly east after having presumably moved northeast overnight given where the plume is. Of note here is the possible to likely presence of lofted or blowing dust that is also moving with the observed smoke. A significant amount of blowing dust was noted a little further west in the analysis last evening, and some enhancements in optical depth are noted downwind of a couple dry lake beds. There may also be some blowing dust mixing in with the smoke southeast of the parent fire. New Mexico… The Cub fire in southwestern New Mexico continues to produce smoke this morning and early afternoon. The moderate density smoke was somewhat stagnant early this morning, but began to move south by around 1400Z. Washington State… A fire in the Saddle Mountains of Washington state was continuing to produce light smoke this morning. The plume extended northeast to just across the Idaho state line and just into British Columbia. UNKNOWN AEROSOL: Central Plains/Midwest/Great Lakes/NE CONUS… A large area of aerosol of unknown origin and composition was observed NE/KS/OK eastward into PA and NY. A front and cyclone draped over the northern Great Lakes and Iowa, respectively, are shunting the northern portions of this area of aerosol towards the south and east. Another cyclone over the Appalachians is forcing this area of aerosol north out of VA and southern WV. There is some possibility that at least some of this aerosol may be composed of leftover smoke from the fires in the Southwestern U.S. and possibly Saharan dust though that cannot be confirmed from satellite imagery. BLOWING DUST: Northern Nevada/Southern Idaho/Northwestern Utah… As mentioned previously in the smoke section, what is likely a mixture of smoke from the fire south of Carson City, remnant blowing dust from yesterday afternoon, and active blowing dust from some of the dry lake beds and desert throughout Nevada was present blanketing much of Nevada, southern Idaho, and far northwestern Utah. Gulf of Mexico/Mexico/Central America/Caribbean Sea/Tropical and Eastern Atlantic… A thin layer of Saharan dust was observed extending from the western Caribbean across the Yucatan into the western Gulf of Mexico, far eastern Mexico, far southern Texas, and southern Louisiana. Another surge of more dense Saharan dust continues to emerge from North Africa extending westward across the Atlantic and over the Leeward Islands, Puerto Rico, and Hispaniola. This leading edge continues to move westward.

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
