Issued by NWS Greenville-Spartanburg SC
AIR QUALITY ALERT IN EFFECT UNTIL MIDNIGHT EDT TONIGHT
The South Carolina Department of Environmental Services (SCDES) has
issued a Code Orange Action Day for fine particulates and ozone for
the Upstate region region of South Carolina. The Air Quality Alert
for fine particulates is in effect until midnight EDT Thursday night,
while the alert for ozone is in effect from 10 AM until 8 PM Thursday.
Southerly winds on the west side of high pressure centered just off
the Southeast coast will continue to transport smoke from the southern
Georgia wildfires into South Carolina. Smoke from the wildfires is
expected to continue to affect the region today and may also
increase ozone concentrations.
An ozone action day means that atmospheric conditions will likely
produce unhealthy concentrations of ground level ozone air pollution.
South Carolina DES recommends that individuals with respiratory health
issues limit time spend outdoors and/or move all activities indoors to
avoid the smoke or fine particulates. Keep windows and doors closed.
Run an air conditioner if you have one but keep the fresh-air intake
closed and the filter clean to prevent outdoor smoke and fine
particulates from getting inside.

AIR QUALITY ALERT IN EFFECT UNTIL MIDNIGHT EDT TONIGHT
The South Carolina Department of Environmental Services (SCDES) has
issued an Air Quality Alert for fine particulates for the following
counties in northeastern South Carolina:
Georgetown and Williamsburg.
The Air Quality Alert is in effect through Thursday, April 23rd. An
Air Quality Alert means that the fine particulate concentrations
within the specified area may approach or exceed unhealthy standards
due to large wildfires burning over southern Georgia.
Southerly winds on the west side of high pressure centered just off
the Southeast coast will continue transport smoke from the southern
Georgia wildfires into South Carolina and the Central Savannah River
Area. As of the early afternoon hours Wednesday, air quality was
already deteriorating over the Central Savannah River Area region
and the Midlands. As stable conditions develop this evening and
overnight, smoke is expected to expand in coverage and become more
noticeable. Smoke from the wildfires is expected to continue to
affect the region on Thursday.
South Carolina Department of Environmental Services recommends that
individuals with respiratory health issues limit time spent outdoors
and/or move all activities indoors to avoid the smoke or fine
particulates. Keep windows and doors closed. Run an air conditioner
if you have one but keep the fresh-air intake closed and the filter
clean to prevent outdoor smoke and fine particulates from getting
inside. Please note that locations closest to the wildfire activity
are more likely to experience smoke at any given time.

Air Quality Alert in effect from 10 AM to 8 PM EDT Thursday
...Corrected to remove Lancaster County from the Alert...
The South Carolina Department of Environmental Services
in Columbia SC has issued a Code Orange Ozone Action Day for the
Central Savannah River region of South Carolina in effect from 10 AM
to 8 PM EDT Thursday.
Stagnant high pressure will bring another day of low humidity
and very warm temperatures to region on Thursday. As there is
already a considerable level of pollutants in the atmosphere,
another day of these conditions will result in significant ozone
production on Thursday. Wildfire smoke may also help to
increase ozone concentrations across parts of the region.
All the remaining South Carolina forecast zones are predicted
to have ground-level ozone peaks in the yellow category.
An ozone action day means that atmospheric conditions will
likely produce unhealthy concentrations of ground level ozone
air pollution. A Code Orange forecast indicates that ground
level ozone concentrations are expected to be unhealthy for
sensitive groups, which includes people with lung disease, older
adults, and children. Sensitive groups should reduce prolonged
or heavy outdoor exertion, take more breaks, and do less intense
activities, especially during afternoon and early evening
hours. You can help prevent ozone pollution by walking or riding
your bicycle, taking your lunch to work, reducing idling,
conserving energy, and keeping your vehicle properly tuned. For
