DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0100Z July 30, 2019
SMOKE: Alaska/Canada/Eastern U.S/North Atlantic/Greenland... Remnant smoke associated with long-range transport from Russian wildfires could be seen stretching across the GOES-17 and GOES-16 fields of view north of 50N. Cloud cover across much of eastern Alaska, the Yukon, the Northwest Territory, and Ontario made smoke detection difficult in those areas. a few larger wildfires were observed emitting dense smoke across the northern portions of the Northwest Territories. Smoke of predominantly light-to-moderate density covers most of the Northwest Territories, eastern British Columbia, southern Alberta, Saskatchewan and Manitoba, extending eastward over Ontario and southern-southeast Quebec. The same plume is seen covering the eastern U.S. including New England, the Mid Atlantic, and the southeastern CONUS. Most of the smoke was moving off toward the east, with some undulations corresponding to troughs/low pressure systems and ridges/high pressure systems throughout the depth of the atmosphere, depending on whether the smoke has its origins in Russia, Alaska, or northern Canada. Oregon/Northern California/Idaho/Montana... The Milepost 97 fire in Oregon remained active emitting thick smoke over much of southern Oregon and far northern California with slow movement towards the south-southeast earlier today then towards the east-southeast in the afternoon. Remnant smoke from yesterday's Milepost 97 smoke plume has moved east-northeastward reaching central Idaho and western Montana. Four Corners... The Castle fire in northern Arizona has remained active throughout the afternoon, emitting thick smoke impacting areas north-northeast of the fire in southern Utah. The Poison Canyon and Peavine Canyon fires in southeastern Utah have also been producing thick smoke, which has been traveling towards the east-southeast into far southwestern Colorado. Remnant smoke from these fires has become incorporated into the monsoonal high entrenched across the Four Corners region, with the smoke covering northeastern Arizona and northwestern New Mexico. DUST... Texas/Western Gulf of Mexico/Bay of Campeche/Yucatan/Western Caribbean A fairly large of area of Saharan dust covers the majority of the western Caribbean, the Yucatan Peninsula, western Gulf of Mexico, and southeast Texas. This area of Saharan dust has been moving around an area of high pressure centered across the eastern Gulf of Mexico/southeastern CONUS. Tropical Atlantic to the Leeward Islands... A second, more expansive impulse of Saharan Dust was observed exiting the African coast and extending/moving westward across the tropical Atlantic today. This layer of dust was caught up in a tropical wave that is moving towards the Windward Island...but flow around the north side of this wave was extending the layer to the Leeward Island and areas north of the Caribbean. 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. 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
