DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z July 1, 2021
SMOKE: Pacific Northwest… Wildfires in northern California and Oregon were helping to produce a light to moderate density layer of remnant smoke over northern California, Oregon, eastern Washington, northern Idaho, and far western Montana. Active moderate to, at times, thick emissions are still observed from northern California and are moving mainly north (Lava and Tennant Fires), with smoke from the Salt Fire moving west. Canada… A large area of moderate to dense smoke was observed stretching from southern British Columbia north into the Northwest Territory and then east across Nunavut and then becoming incorporated into an area of high pressure over northern Saskatchewan, northern Manitoba, and the eastern portions of Hudson Bay. Most of the smoke was being absorbed by the high, but some could be moving across Hudson Bay as well. The parent activity of this smoke is a combination of wildfire activity across British Columbia and the western CONUS, as well as possibly some minor contribution from wildfire activity in Alaska and the Yukon. Active smoke plumes were observed moving north-northwest across southern British Columbia. Northern Plains/Southern Prairie Provinces… A layer of varying density remnant smoke was seen extending from southeastern Manitoba into northern Iowa and eastern Nebraska. The parent activity for this smoke is wildfire activity across southeastern Manitoba. Although the remnant smoke is moving south-southeast, the active smoke plumes are extending mainly to the northwest. Alaska/Yukon… Persistent wildfire activity was observed emitting thick smoke. Smoke from the wildfire in central Alaska was moving west, while smoke from the wildfire in eastern Alaska was filling up a valley before moving off toward the east-northeast. DUST: Tropical Atlantic/Eastern Caribbean… A Saharan Air Layer was observed moving westward across the tropical Atlantic and across the northern Windward Islands and the Leeward Islands around the northern periphery of Tropical Storm Elsa. 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
