The city's Regulatory Compliance Department issued an air quality advisory on Wednesday afternoon for possible elevated ozone levels.
This is the second advisory this month. The last came on May 6.
Channel 4 meteorologist John Gaughan said the levels become elevated because of car exhaust, hot temperatures and light winds.
“It's hazy outside. You can pretty much see it as you drive around town,” Gaughan said. “The important detail here is that if you are sensitive, or the elderly or very, very young can find it as an irritant (with) sore throat (or) scratchy throat.
“To avoid it, just stay indoors during these afternoon and evening hours until things begin to settle down, as they usually do. Early morning hours are better for most folks.”
The city also recommends avoiding strenuous outdoor activities.
