THROUGH 0015Z September 24, 2023
SMOKE: Canada.. Extremely high wildfire activity was observed again this afternoon across northern British Columbia, Alberta, and Saskatchewan, resulting in a very large and thick smoke plume spreading from northeastern British Columbia, through south-central Northwest Territories, into northern Nunavut, and over a wide portion of the Hudson Bay. Moderate-density smoke could also be seen stretching across northern Saskatchewan and northern Manitoba, with lighter smoke extending further eastward and reaching Newfoundland and the northwestern Atlantic. Mississippi Valley... Widespread agricultural burning was observed along the Mississippi Valley leading to a pocket of moderate smoke along eastern Arkansas. Light-density smoke extended over southeastern Missouri and southern Arkansas. Remnant light smoke from previous day burning in this areas was also seen over southeastern Louisiana and over the central Gulf of Mexico. Northwestern California and southwestern Oregon… A few wildfires in northwestern California and southwestern Oregon were producing moderate- to heavy-density smoke plumes which were dispersing towards the northeast over central-northeastern Oregon and southeastern Washington. DUST: Oregon... Blowing dust was observed off the dry lakebed of Summer Lake in southern Oregon. The dust plume was dispersing towards the northeast for about 50 miles.
