Air Quality Alert Days

Along with warmer temperatures, summer is the season for Air Quality Alert Days when high ground-level ozone (smog) is anticipated.

Elevated ozone levels cause health problems, especially for children, senior citizens and people with respiratory diseases. It's wise to cut back on driving and reschedule strenuous activities when Air Quality Alert Days are forecast.
