Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.

Forecast Discussion: Current conditions: At 2 p.m. EDT this Monday afternoon, low pressure located along the South Carolina coast was bringing an east to southeasterly flow to the region. Plenty of cloudiness will prevail with showers and some drizzle this afternoon. The onshore flow has acted to produce low levels of fine particulate across the area. This low will slowly move northward over the next 36 to 48 hours, weakening some as it does so. Periods of steadier rain will occur overnight tonight. *** Tuesday's forecast: Overcast and breezy Tuesday with periods of rain and drizzle continuing, and a gusty east wind will keep fine particulate low. Clouds Tuesday night with rain tapering to drizzle. *** Extended forecast: Clouds will linger into the afternoon hours on Wednesday, with some sunshine appearing late in the afternoon. Lighter winds will allow fine particulate matter to rise some, but this will remain in the upper good range. As a ridge of high pressure builds across the eastern U.S. later this week, it will turn much warmer, beginning on Thursday and continuing into the weekend. With the summer like temperatures, will come a rise in both fine particulate matter and ozone. Both of these pollutants have the potential to rise into the moderate range Thursday and Friday.---McAuliffe
