Alerts in force

An Air Quality Alert is issued by the National Weather Service on behalf of a state or local agency when pollution is expected to reach a level that harms health. An Air Stagnation Advisory means the air will not move enough to clear what is already in it.

None are in force near South Canal right now. All Ohio warnings.

The forecaster’s discussion

Written by Eastgate Regional Council of Governments for Youngstown and filed with AirNow.

Friday, September 25 through Sunday, September 27: With a surface ridge of high pressure to the north and a strengthening low-pressure system off the Mid-Atlantic coast, northerly to northeasterly winds will disperse pollutants and transport a clean air mass into northeastern Ohio. In addition, mild temperatures will limit ozone formation, leading to Good AQI levels on all three days. Monday, northerly winds and dispersion will gradually decrease as the surface ridge moves into Ohio. However, pollutant carryover will be low, while partly cloudy skies and mild temperatures keep ozone development in check. Therefore, AQI levels will remain Good. Tuesday and Wednesday, as the surface ridge moves east, winds will shift to southeasterly, gradually transporting regional pollutants into the Mahoning Valley. However, pollutant carryover will remain low, yielding high-Good AQI levels on both days.

Fine particles in micrograms per cubic meter, ozone in parts per billion as an 8-hour average. The index for each hour is EPA’s: the ozone figure is already the 8-hour average the ozone index is defined on, and the particle figure is run through EPA’s NowCast, which is how an hourly PM2.5 concentration becomes an index.

Smoke

NOAA’s Hazard Mapping System analysts drew light smoke over South Canal in satellite imagery today (Fri, 8:00 AM EDT to Fri, 11:00 AM EDT). That is smoke seen from above; it is not always smoke at ground level.

NOAA’s model forecasts no measurable smoke near the ground here over the next two days.

What this means

Moderate

Air quality is acceptable. There may be a risk for some people, particularly those who are unusually sensitive to air pollution.

Who is affected
People who are unusually sensitive to ozone or fine particles.
What to do
If you are unusually sensitive, consider making long or intense outdoor activity shorter or easier.
Index range
51 to 100

Category descriptions are the Environmental Protection Agency’s own.

What these numbers are. An index beside a monitor’s name is a measurement, published hourly by AirNow and preliminary until the operating agency certifies it. A category for today or tomorrow is a state or local agency forecaster’s own forecast for a reporting area. An hourly index is NOAA’s air quality model on a five-kilometer grid, not a reading from any instrument. Where a town has no monitor within reach, only the model figures appear, and the page says so.
