DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0330Z August 21, 2017
SMOKE: Northern US and California... A large swath of remnant smoke, mainly from the long burning wildfires in Oregon, Washington, northern California, Idaho and Montana, was seen covering a large portion of the northern US and northern and central California. From California and southwest Oregon the smoke extended to the east across southern Idaho, northern Wyoming and eastern Montana into the northern Plains, upper Mississippi Valley and western Great Lakes. The smoke also covered much of New England and the northern mid Atlantic into the Gulf of Maine. The extent of the smoke was quite uncertain over western Montana and northern Idaho as cloud cover made detection of the smoke difficult. The thickest smoke was seen over northern California and southwest Oregon. This batch of smoke was moving to the south southwest and extending into the Pacific off of much of the California coast. A separate area of mostly light remnant smoke was seen over central and eastern Washington. Pacific Ocean/Hawaii... An area of light remnant smoke was seen over the Pacific extending from the western main Hawaiian Islands north northeast to near 50N138W and then curling back to the southeast. Eastern Canada... Remnant smoke was seen over most of eastern Canada covering much of eastern Ontario, western and central Quebec, all of Hudson Bay and nearly all of Nunavut. A large patch of moderately dense smoke covered the high Arctic and the eastern Canadian archipelago. Two stripes of light smoke were seen stretching from northwest to southeast. One extended from the southern Yukon/Northwest Territories border to west central Alberta and the other from northwest Northwest Territories to the northwest border of Alberta.

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/Products/land/hms.html GIS: http://www.firedetect.noaa.gov/viewer.htm KML: http://www.ssd.noaa.gov/PS/FIRE/kml.html ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO SSDFireTeam@noaa.gov
