DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z July 16, 2021
SMOKE: Canada/U.S./North Atlantic/Pacific off the coast of California/Baja... The extremely large area of varying density smoke attributed mainly to very significant wildfire activity occurring in portions of central and western Canada and the western U.S. was again visible this morning over a good portion of the U.S. with the exception of the far western portions of California, Oregon, and Washington. Other relatively smoke free areas in satellite imagery included a portion of the southwestern U.S. and parts of the south central and southeastern U.S. Smoke also was seen over southwestern, central, and eastern Canada though a portion of Quebec appeared to be relatively smoke free though cloud cover there may also have limited additional information on the smoke in satellite imagery. Within this huge mass of smoke were moderately dense to thick smoke which appeared over a broad region stretching from the interior portion of the northwestern U.S. and southwestern Canada eastward over the northern tier of the U.S. and over much of central Canada. A separate patch of moderately dense smoke extended from the Mid-Atlantic region over the Northeast and offshore over the nearby far western Atlantic. Farther to the east, a detached mass of moderate to thick density smoke was located over the Atlantic to the south and southeast of Greenland. Additionally, some of the thinner density smoke also was barely visible off the west coast of southern California and Baja. Alaska/Northwestern Canada… Wildfire activity mainly in central Alaska was responsible for an area of thin to moderate density smoke which covered much of central and southern Alaska. A separate stripe of thinner density smoke likely also from the Alaska fires and possibly from recent fires in the Yukon of northwestern Canada was seen across the central Yukon and over the central part of the Northwest Territories. DUST: Southern and Eastern Texas/Eastern Mexico/Northern Central America/Gulf of Mexico/Caribbean Region... Saharan dust was visible this morning over the western Gulf of Mexico, northern Central America, southeastern and eastern Mexico, and extending up into southern and southeastern Texas. A much larger and thicker area of Saharan dust could be seen east of Puerto Rico and extending all the way to western Africa. 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
