DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0130Z JULY 19, 2008
SO2 and Volcanic Ash from Okmok Volcano crossing Northern US/Southern Canada: A narrow plume of SO2 was clearly seen in late day visible imagery stretching east northeastward from the Pacific, entering the US just north of the Washington/Oregon border and continuing across northern Idaho and central Montana into extreme southeastern Saskatchewan before turning east southeast across southern Manitoba, south central Ontario, southern Quebec, the mouth of the St. Lawrence into Newfoundland. The plume may contain volcanic ash west of 107W based on PIREPS. Mid and Southern California: The Basin Complex in Monterey county generated a plume of moderate to dense smoke that extended south over the ocean. Northern California: The fires in Northern CA continue to produce dense smoke near the sources with moderate smoke extending east-northeast across northern Nevada, southeast Oregon and southern Idaho. Additional light smoke extended much farther...over the central and northern Plains, the Upper Midwest and the Great Lakes. Northwest Territories/Manitoba: Large area of smoke of various thicknesses covered northern Manitoba and central Northwest Territories. The smoke was moving north and east before turning south over Hudson Bay. Virginia: A handful of fires in central and southern Virginia generated light smoke that moved towards the north and northwest.
