Earlier on Tuesday the N.J. Department of Environmental Protection issued an Air Quality Alert for Bergen 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, would put older adults, children and those with heart and lung conditions at greater risk from exposure to ozone.

The DEP recommended limiting outdoor activity for those groups. The alert was said to be in effect until 10 p.m., according to the National Weather Service.
