The N.J. Department of Environmental Protection has issued an Air Quality Alert for Essex County Tuesday, warning residents the state's Air Quality Index is at the “unhealthy for sensitive groups” status.

Hot temperatures across the state, combined with sunny skies and southwest winds, the DEP says, will put older adults, children and those with heart and lung conditions at greater risk from exposure to ozone.

The DEP recommends limiting outdoor activity for those groups. The alert is in effect until 10 p.m., according to the National Weather Service.

Thunderstorms in the forecast for later in the day Tuesday are expected to alleviate the poor air quality conditions.

The National Weather Service says to expect scattered showers and thunderstorms in Essex County, mostly after 3 p.m., with a high near 90. Chance of precipitation is 30%.
