FUNNY RIVER FIRE DIMINISHING; HIGH LEVELS OF OZONE IN SOUTHERN CALIFORNIA

Just a quick update on the Funny River Fire: the giant plumes of thin to medium smoke hovering over most of Northern Canada last week have now diminished to a smaller plume of thin smoke near the Hudson Bay area, as seen in the HMS Fire and Smoke image below. Most of the actual Funny River Fire has been contained, but still burns with little to no smoke. As of yesterday, June 1, over 193,243 acres were burned and 58% of the fire was contained (courtesy of inciweb.nwcg.gov).

In other news, high concentrations of ozone were seen in Southern California this morning, reaching levels of Unhealthy for Sensitive Groups. Levels dropped to Moderate and began losing coverage in the area until early this afternoon, increasing around 2:00 PM, as seen in the EPA AQI loop below (top left). Presumably, the low pressure front moving in over the West Coast caused the mixing in the atmosphere, decreasing the concentration of ozone in the area (weather map courtesy of the Weather Channel, top right). A few fires were also observed in Southern California, as seen in the Google Earth image below (bottom left), possibly contributing to the increased ozone concentration as well as the surrounding areas of Moderate to Unhealthy for Sensitive Groups AQIs.
