Unhealthy for Sensitive Groups AQI in Pacific Northwest; Elevated AOD along portions of eastern seaboard

Scattered patches of Moderate (Code Yellow) indices were recorded across the Pacific Northwest today, with the worst conditions along northern California and Southern Oregon border (top left, courtesy AIRNow). Elsewhere in the United States, scattered Moderate conditions for PM2.5 were measured in the Rocky Mountain states and across eastern Indiana. The National Weather Service's Air Quality division forecasts elevated 1-hour vertical smoke across the eastern seaboard stretching from Florida thru the Virginia coastline and over the Atlantic (bottom,left). Today's MODIS pass from the Terra satellite suggests elevated AOD in the same region, collocated to a plethora of wildfires (according to the HMS analysis) (bottom right).
On the international front, more bad news for air quality in Beijing, as "hazardous" pollution levels are expected to continue effecting the region until a mid-week weather system ushers in a new airmass.
