An Air Quality Alert is in effect in Maine Wednesday, July 31 from 11 a.m. to 11 p.m. It includes areas around the coast, from Kittery to Acadia National Park.
The Alert is scheduled because high levels of ozone are expected to create air quality issues throughout the day. Particle pollution will be at a moderate level, which is not enough to trigger an alert -- but it will add to the already-existing pollution.
Mainers will also be dealing with another hot and humid day Wednesday before scattered showers and thunderstorms in the afternoon and evening. Any rain will help with pollution levels.
When an Air Quality Alert is in effect, the Maine Department of Environmental Protection recommends limiting strenuous outdoor activity, especially for the very young, elderly, and anyone with respiratory problems.
