Hanna about to reach South Carolina coast, moderate AQ in the East

The center of tropical storm Hanna is off the Georgia coast right now (right: NWS Hurricane Center track forecast; left: UW MODIS Today rgb from MODIS Aqua and EPA AIRNow PM2.5), see right image with forecasted track as of 5 PM EDT. As you can see (compare to Amy's post on Tuesday), the storm track has shifted east. Hanna will reach southern VA around 2 pm tomorrow and the D.C area later in the afternoon and it is expected that it will bring good air quality to the east. The storm has already brought good air quality to the southeast, but air quality is still primarily in the moderate range over the northeast (bottom: UW MODIS Today rgb from MODIS Terra and EPA AIRNow PM2.5). Ozone was the lead pollutant in some parts of New York, leading to code orange conditions in Albany.
