Air Quality Alert issued July 17 at 12:43AM EDT by NWS Wilmington OH
Jul 17, 12:43 AM Jul 18, 12:00 AM
The Miami Valley Regional Planning Commission and the Regional Air
Pollution Control Agency have issued an Air Quality Alert for Clark,
Darke, Greene, Miami, Montgomery, Preble, and Shelby counties in the
Miami Valley Region, until midnight tonight.

Fine particulate levels are expected to be in the 'Unhealthy for
Sensitive Groups' range. Active children and adults, and people with
respiratory disease, such as asthma should limit prolonged outdoor
exposure.

For additional actions and information, visit miamivalleyair.org or
call 937-223-6323

Additionally, the Ohio Environmental Protection Agency has issued a
statewide Air Quality Advisory for the entire state of Ohio as smoke
from Canadian wildfires continues to adversely impact air quality.

Pollutants across the state are expected to range from the
'Unhealthy For Sensitive Groups' category in the southwest part of
the state to the 'Unhealthy' category in the rest of the state.
Hourly concentrations at times may reach the 'Very Unhealthy' to
'Hazardous' categories.

It is recommended, when possible, to avoid strenuous outdoor
activities, especially those with heart disease and respiratory
conditions like asthma. Watch for symptoms including wheezing,
coughing, chest tightness, dizziness, or burning in the nose,
throat, and eyes.

Protection Agency's website at epa.ohio.gov.
