Hot weather likely to choke off air quality

Star Tribune

Last update: July 22, 2007 - 11:20 PM

Hot weather and sunny skies predicted for much of this week have led state officials to issue a caution to Twin Cities residents about a potential dip in air quality. Ozone levels, which increase when pollutants combine with sunlight, are expected to spike because of the lack of cloud cover, state officials said.

Who's affected: Diminished air quality has the greatest effect on children, the elderly and those with respiratory or cardiovascular illnesses. It's recommended that people in these groups avoid exerting themselves outdoors for long periods.

FOR THE WEEK

Today: Moderate air quality readings, one step below good.

Tuesday: Moderate.

Wednesday: Air quality readings expected to be "unhealthy for sensitive groups."

Thursday: Unhealthy for sensitive groups.

Friday: Arriving cold front, cloudier skies expected to return level back to moderate.
